Iran is not known to currently possess weapons of mass destruction (WMD) and has signed treaties repudiating the possession of WMD including the Biological Weapons Convention, Iran has first hand knowledge of WMD effects—over 100,000 Iranian troops and civilians were victims of chemical weapons during the 1980s Iran–Iraq War. In 2003 the Supreme Leader of Iran, Ayatollah Ali Khamenei, along with other clerics, issued a public and categorical religious decree (fatwa) against the development, production, stockpiling and use of nuclear weapons, though it is approved by some relatively minor clerics. Later versions of this fatwa forbid only the "use" of nuclear weapons, but said nothing about their production. Iran has stated its uranium enrichment program is exclusively for peaceful purposes. The IAEA has confirmed the non diversion of declared nuclear material in Iran but has also said it "needs to have confidence in the absence of possible military dimensions to Iran’s nuclear program." In December 2014, a Wisconsin Project on Nuclear Arms Control report by Lincy and Milhollin based on IAEA data concluded that Iran could produce enough weapons grade uranium for one nuclear warhead in 1.7 months. In 2012, sixteen U. S. intelligence agencies, including the CIA, reported that Iran was pursuing research that could enable it to produce nuclear weapons, but was not attempting to do so. In 2010 and 2011, the senior officers of all of the major American intelligence agencies stated that there was no conclusive evidence that Iran has made any attempt to produce nuclear weapons since 2003. In a 2007 National Intelligence Estimate, the United States Intelligence Community assessed that Iran had ended all "nuclear weapon design and weaponization work" in 2003. Then U. S. Defense Secretary Leon Panetta stated in January 2012 that Iran was pursuing a nuclear weapons capability, but was not attempting to produce nuclear weapons. In 2009, U. S. intelligence assessed that Iranian intentions were unknown. Some European intelligence believe Iran has resumed its alleged nuclear weapons design work. In 2011, then Russian President Dmitry Medvedev said Iran was close to having the capability to produce nuclear weapons. Iran has called for nuclear weapons states to disarm and for the Middle East to be a nuclear weapon free zone. Turkey, China, Syria, Afghanistan, the Gulf Cooperation Council, and the Arab League have expressed their support for Iran's right to develop peaceful nuclear energy. >

After the IAEA voted in a rare non consensus decision to find Iran in non compliance with its NPT Safeguards Agreement and to report that non compliance to the UN Security Council, the Council demanded that Iran suspend its nuclear enrichment activities and imposed sanctions against Iran when Iran refused to do so. Former Iranian President Mahmoud Ahmadinejad argued that the sanctions were illegal. The IAEA has been able to verify the non diversion of declared nuclear material in Iran, but not the absence of undeclared activities. The Non Aligned Movement has called on both sides to work through the IAEA for a solution. a resolution against Iran which urged Iran to apply the modified Code 3.1 to its Safeguard Agreement, urged Iran to implement and ratify the Additional Protocol, Iran said the "hasty and undue" resolution would "jeopardize the conducive environment vitally needed" for successful negotiations. recalled a previous Iranian "policy of concealment" regarding its enrichment program and found that Iran had violated its NPT Safeguards Agreement. Another IAEA report stated "there is no evidence that the previously undeclared nuclear material and activities were related to a nuclear weapons program." Gawdat Bahgat of the National Defense University speculates that Iran may have a lack of confidence in the international community which was reinforced when many nations, under pressure from the United States, rejected or withdrew from signed commercial deals with the Iranian nuclear authority. On 31 July 2006, the UN Security Council passed a resolution demanding Iran suspend its enrichment program. On 25 October 2007, the United States declared the Revolutionary Guards a "proliferator of weapons of mass destruction", and the Quds Force a "supporter of terrorism". Iran responded that "it is incongruent for a country [US] who itself is a producer of weapons of mass destruction to take such a decision." Speaking in Washington in November 2007, days before the IAEA was to publish its latest report, Israeli Deputy Prime Minister Shaul Mofaz called for ElBaradei to be sacked, saying: "The policies followed by ElBaradei endanger world peace. His irresponsible attitude of sticking his head in the sand over Iran's nuclear programme should lead to his impeachment." Israel and some western governments fear Iran is using its nuclear programme as a covert means to develop weapons, while Iran says it is aimed solely at producing electricity. For its part in the conflict ridden Middle East, Israel is a member of the IAEA, but it is not itself a signatory to the Nuclear Non Proliferation Treaty, and is widely believed to currently be the only nuclear armed state in the region.

Iran's nuclear program began as a result of the Cold War alliance between the United States and the Shah of Iran, Mohammad Reza Pahlavi, who emerged as an important US ally in the Persian Gulf. Under the Atoms for Peace program, Iran received basic nuclear research facilities from the United States. In return, Tehran signed the Treaty on the Non Proliferation of Nuclear Weapons (NPT) in 1968. Fueled by high oil prices in the 1970s, Iran sought to purchase large scale nuclear facilities from Western suppliers in order to develop nuclear power and fuel cycle facilities with both civilian and potential military applications. Sensing a heightened risk of nuclear proliferation, the United States convinced Western allies to limit the export of nuclear fuel cycle facilities to Iran. Supreme Leader Ayatollah Ruhollah Khomeini, whose revolution displaced the Shah's monarchy in 1979 and ruled the newly established Islamic Republic of Iran until his death in 1989, placed little emphasis on nuclear weapons development because it was viewed as a suspicious Western innovation. During that time, many of Iran's top scientists fled the country while the United States organized an international campaign to block any nuclear assistance to Iran. Following the death of Ayotollah Khomeini, the leadership of President Ali Akbar Hashemi Rafsanjani and Supreme Leader Ali Hosseini Khamenei sought to revive Iran's overt nuclear civilian program and expand undeclared nuclear activities during the 1990s. According to a strategic dossier from International Institute for Strategic Studies, Iran turned away from Western suppliers and obtained nuclear assistance from Russia and China in a number of key areas, including uranium mining, milling and conversion, as well as technology for heavy water research reactors. A 2005 US National Intelligence Estimate stated that Iran was ten years from making a nuclear weapon. In 2006 Ernst Uhrlau, the head of German intelligence service, said Tehran would not be able to produce enough material for a nuclear bomb before 2010 and would only be able to make it into a weapon by about 2015. A 2007 annual review the International Institute for Strategic Studies in London stated that "If and when Iran does have 3,000 centrifuges operating smoothly, the IISS estimates it would take an additional 9 11 months to produce 25 kg of highly enriched uranium, enough for one implosion type weapon. That day is still 2–3 years away at the earliest." The former head of the IAEA, Mohamed ElBaradei, said on 24 May 2007 that Iran could take between 3 and 8 years to make a bomb if it went down that route. In December 2007, the United States National Intelligence Estimate (representing the consensus view of all 16 American intelligence agencies) concluded with a "high level of confidence" that Iran had halted its nuclear weapons program in 2003 and "with moderate confidence" that the program remained frozen as of mid 2007. The new estimate says that the enrichment program could still provide Iran with enough raw material to produce a nuclear weapon sometime by the middle of next decade, but that intelligence agencies "do not know whether it currently intends to develop nuclear weapons" at some future date. Iranian Foreign Minister Manouchehr Mottaki said 70 percent of the U. S. report was "true and positive," but denied its allegations of Iran having had a nuclear weapons program before 2003. Russia has said there was no proof Iran has ever run a nuclear weapons program. The former head of the IAEA, Mohamed ElBaradei, stated that he had seen "maybe some studies about possible weaponization", but "no evidence" of "an active weaponization program" as of October 2007. A National Intelligence Estimate (NIE) is the most authoritative written judgment concerning a national security issue prepared by the Director of Central Intelligence. The U. S. Director of National Intelligence said in February 2009 that Iran would not realistically be able to a get a nuclear weapon until 2013, if it chose to develop one., Mossad Chief Meir Dagan was more cautious, saying recently that it would take the Iranians until 2014. German, French, and British intelligence said that under a worst case scenario it would take Iran a minimum of 18 months to develop a nuclear weapon if it chose to build one, and it would have to first purify its uranium and weaponize its uranium. An anonymous source in the German Foreign Intelligence Service (BND) whose rank was not provided has gone further and claimed Iran could produce a nuclear bomb and conduct an underground test in 6 months if it wanted to and further asserted that Iran had already mastered the full uranium enrichment cycle, and possessed enough centrifuges to produce weapons grade uranium. Physicists said that if Iran were to choose to develop a nuclear weapon, it would have to withdraw from the International Nuclear Non Proliferation Treaty and expel International Atomic Energy Agency inspectors from the country. George Friedman, head of the global intelligence company Stratfor, has said Iran is "decades away" from developing any credible nuclear arms capacity. On 12 February 2010 US think tank expert David Albright, the head of the Institute for Science and International Security, said in a report that Iran was seeking to "make sufficient weapons grade uranium". An IAEA report issued 8 November 2011 provided detailed information outlining the IAEA's concerns about the possible military dimensions of Iran's nuclear program, noting that Iran had pursued a structured program or activities relevant to the development of nuclear weapons. On 30 April 2018, Israeli Prime Minister Binyamin Netanyahu revealed thousands of files he said were copied from a "highly secret location" in Teheran which show an Iranian effort to develop nuclear weapons between 1999 and 2003. On 1 May 2018 the IAEA reiterated its 2015 report, saying it had found no credible evidence of nuclear weapons activity in Iran after 2009. In 2021, a group of former Republican officials including ex CIA director James Woolsey, wrote in the National Review that "Iran probably has already the atomic bomb," citing past detection failures by U. S. intelligence and the IAEA.

The International Atomic Energy Agency (IAEA) is an autonomous international organization that seeks to promote the peaceful use of nuclear energy and to inhibit its use for military purposes. On 6 March 2006, the IAEA Secretariat reported that "the Agency has not seen indications of diversion of nuclear material to nuclear weapons or other nuclear explosive devices however, after three years of intensive verification, there remain uncertainties with regard to both the scope and the nature of Iran's nuclear programme". However, the inspectors did find some sensitive documents, including instructions and diagrams on how to make uranium into a sphere, which is only necessary to make nuclear weapons. Iran furnished the IAEA with copies, claiming not to have used the information for weapons work, which it had obtained along with other technology and parts in 1987 and the mid 1990s. It is thought this material was sold to them by Abdul Qadeer Khan, though the documents did not have the necessary technical details to actually manufacture a bomb. On 18 December 2003, Iran voluntarily signed, but did not ratify or bring into force, an Additional Protocol that allows IAEA inspectors access to individuals, documentation relating to procurement, dual use equipment, certain military owned workshops, and research and development locations. Iran agreed voluntarily to implement the Additional Protocol provisionally, however when the IAEA reported Iran's non compliance to the United Nations Security Council on 4 February 2006 Iran withdrew from its voluntary adherence to the Additional Protocol. On 12 May 2006, claims that highly enriched uranium (well over the 3.5% enriched level) was reported to have been found "at a site where Iran has denied such sensitive atomic work", appeared. "They have found particles of highly enriched uranium [HEU], but it is not clear if this is contamination from centrifuges that had been previously found [from imported material] or something new," said one diplomat close to the UN International Atomic Energy Agency (IAEA). These reports have not yet been officially confirmed by the IAEA (as of 1 June 2006). On 31 July 2006, the United Nations Security Council passed a resolution demanding that Iran suspend its uranium enrichment activities. In 2007 these traces were determined to have come from leaking used highly enriched uranium fuel from the Tehran Research Reactor, which the U. S. supplied to Iran in 1967, and the matter was closed. In July 2007 the IAEA announced that Iran has agreed to allow inspectors to visit its Arak nuclear plant, and by August 2007 a plan for monitoring the Natanz uranium enrichment plant will have been finalised. In August 2007 the IAEA announced that Iran has agreed to a plan to resolve key questions regarding its past nuclear activities. The IAEA described this as a "significant step forward". In September 2007 the IAEA announced it has been able to verify that Iran's declared nuclear material has not been diverted from peaceful use. While the IAEA has been unable to verify some "important aspects" regarding the nature and scope of Iran's nuclear work, the agency and Iranian officials agreed on a plan to resolve all outstanding issues, Director General Mohamed ElBaradei said at the time. In an interview with Radio Audizioni Italiane the same month, ElBaradei remarked that "Iran does not constitute a certain and immediate threat for the international community". In October 2007, ElBaradei amplified these remarks, telling Le Monde that, even if Iran did intend to develop a nuclear bomb, they would need "between another three and eight years to succeed". He went on to note that "all the intelligence services" agree with this assessment and that he wanted to "get people away from the idea that Iran will be a threat from tomorrow, and that we are faced right now with the issue of whether Iran should be bombed or allowed to have the bomb". In November 2007 ElBaradei circulated a report to the upcoming meeting of the IAEA Board of Governors. Its findings conclude that Iran has made important strides towards clarifying its past activities, including provided access to documentation and officials involved in centrifuge design in the 1980s and 1990s. Answers provided by Iran regarding the past P 1 and P 2 centrifuge programs were found to be consistent with the IAEA's own findings. However, Iran has ignored the demands of the UN Security council, and has continued to enrich uranium in the past year. The IAEA is not able to conclusively confirm that Iran isn't currently enriching uranium for military purposes, as its inspections have been restricted to workshops previously declared as part of the civilian uranium enrichment program, and requests for access to certain military workshops have been denied; the report noted that "As a result, the agency's knowledge about Iran's current nuclear program is diminishing". The report also confirmed that Iran now possesses 3000 centrifuges, a 10 fold increase over the past year, though the feed rate is below the maximum for a facility of this design. Data regarding the P 2 centrifuge, which Ahmadinejad has claimed will quadruple production of enriched uranium, was provided only several days before the report was published; the IAEA plan to discuss this issue further in December. In response to the report the US has vowed to push for more sanctions, whilst Iran has called for an apology from the US. In his final November 2009 statement to the IAEA Board of Governors, Mohamed ElBaradei said the Agency continued to verify the non diversion of declared nuclear material in Iran, but that other issues of concern had reached a "dead end" unless Iran were to fully cooperate with the agency. ElBaradei stated it would be helpful if "we were able to share with Iran more of the material that is at the centre of these concerns", and also said it would be helpful if Iran fully implemented the Subsidiary Arrangements to its Safeguards Agreement and fully implemented the Additional Protocol. ElBaradei said Iran's failure to report the existence of a new fuel enrichment facility until September 2009 was inconsistent with its obligations under the Subsidiary Arrangements to its Safeguards Agreement. ElBaradei closed by saying international negotiations represented a "unique opportunity to address a humanitarian need and create space for negotiations". On 18 February 2010 the IAEA released a new report on Iran's nuclear program. Ivan Oelrich and Ivanka Barzashka, writing in the Bulletin of the Atomic Scientists, suggested "the media has seriously misrepresented the actual contents of the report" and that "in fact, no new information has been revealed." They wrote that there was "no independent assessment that Iran is engaged in weapons work" and that this was "hardly the first time that the agency has discussed potential evidence of Tehran's nuclear weapons research". Iran's envoy to the UN atomic watchdog criticized Western powers for interpreting the IAEA report in an "exaggerated, selective and inaccurate" manner. In an April 2010 interview with the BBC, former IAEA Director General ElBaradei said Western nations were seeking harsher sanctions "out of frustration". "I don't think Iran is developing, or we have new information that Iran is developing, a nuclear weapon today there is a concern about Iran's future intentions, but even if you talk to MI6 or the CIA, they will tell you they are still four or five years away from a weapon. So, we have time to engage," he said. ElBaradei further said the building of trust between the parties would "not happen until the two sides sit around the negotiating table and address their grievances. Sooner or later that will happen."

Former IAEA Director General ElBaradei said in 2009 that the agency had been provided with "no credible evidence" that Iran is developing nuclear weapons, but the New York Times reported in January 2009 that the IAEA is investigating U. S. allegations Project 110 and Project 111 could be names for Iranian efforts for designing a nuclear warhead and making it work with an Iranian missile. "We are looking to those suppliers of information to help us on the question of authenticity, because that is really a major issue. It is not an issue that involves nuclear material; it's a question of allegations," ElBaradei further said. when a November 2009 article in The Guardian said the allegations included Iran's weapon design activities using two point implosion designs. The New York Times article cited classified US intelligence reports asserting that Professor Mohsen Fakhrizadeh is in charge of the projects, while Iranian officials assert these projects are a fiction made up by the United States. Outside experts note that the parts of the report made public lack many dates associated with Iran's alleged activities meaning it is possible Iran had a Project 110 at one time, but scrapped it as US intelligence insists. The Washington Post reported that "nowhere are there construction orders, payment invoices, or more than a handful of names and locations possibly connected to the projects." Former IAEA Director ElBaradei said the Agency didn't have any information that nuclear material has been used and didn't have any information that any components of nuclear weapons had been manufactured. Iran has asserted that the documents are a fabrication, while the IAEA has urged Iran to be more cooperative and Member States to provide more information about the allegations to be shared with Iran. In August 2009 an article in the Israeli newspaper Haaretz alleged that ElBaradei had "censored" evidence obtained by IAEA inspectors over the preceding few months. ElBaradei has angrily rejected claims from Israel, France and the US that he had suppressed the internal IAEA report, saying all relevant and confirmed information had been presented to member states. Russia has denied allegations of "continued Russian assistance to Iran's nuclear weapons program" as "totally groundless" and said the November 2009 IAEA report reaffirmed the absence of a military component in Iran's efforts in the nuclear field. In December 2009, The Times claimed that a document from an unnamed Asian intelligence agency described the use of a neutron source which has no use other than in a nuclear weapon, and claimed the document appeared to be from an office in Iran's Defense Ministry and may have been from around 2007. Norman Dombey, professor emeritus of theoretical physics at Sussex University, wrote in that "nothing in the published 'intelligence documents' shows Iran is close to having nuclear weapons" and argued that it is "unlikely that nuclear weapon projects would be distributed among several universities, or weapon parts marketed to research centres." A senior U. N. official who saw the document said it may or may not be authentic, that it was unclear when the document was written, and that it was unclear whether any experiments had ever actually been performed. The C. I. A. did not declare whether it believes the document was real, and European spy agencies also did not give any authentication to the document. Anton Khlopkov, the founding director of the Center for Energy and Security Studies, said the media leak may be being used "as a pretext for inciting the campaign against Iran." Former Russian Prime Minister Yevgeny Primakov has also said after the public publications of the documents "Russia has no concrete information that Iran is planning to construct a weapon". Russia's representative to the IAEA, Alexander Zmeyevskiy, has noted that though the IAEA is in possession of these documents, the IAEA's findings "do not contain any conclusions about the presence of undeclared nuclear activities in Iran." Iran pointed out the claims had not been verified by the International Atomic Energy Agency and argued that "some countries are angry that our people defend their nuclear rights." "I think that some of the claims about our nuclear issue have turned into a repetitive and tasteless joke," Iranian President Mahmoud Ahmadinejad said in response to the documents.

Iran states that the purpose of its nuclear program is the generation of power and that any other use would be a violation of the Nuclear Non Proliferation Treaty, of which it is a signatory, as well as being against Islamic religious principles. Iran claims that nuclear power is necessary for a booming population and rapidly industrialising nation. It points to the fact that Iran's population has more than doubled in 20 years, the country regularly imports gasoline and electricity, and that burning fossil fuel in large amounts harms Iran's environment drastically. Additionally, Iran questions why it shouldn't be allowed to diversify its sources of energy, especially when there are fears of its oil fields eventually being depleted. It continues to argue that its valuable oil should be used for high value products and export, not simple electricity generation. Furthermore, Iran argues that nuclear power makes fairly good economic sense. Building reactors is expensive, but subsequent operating costs are low and stable, and increasingly competitive as fossil fuel prices rise. Iran also raises funding questions, claiming that developing the excess capacity in its oil industry would cost it $40 billion, not to speak of paying for the power plants. Harnessing nuclear power costs a fraction of this, considering Iran has abundant supplies of accessible uranium ore. These claims have been echoed by Scott Ritter, the former UN weapons inspector in Iraq. Roger Stern, of Johns Hopkins Department of Geography and Environmental Engineering, agrees "Iran's claims to need nuclear power could be genuine". Iran states it has a legal right to enrich uranium for peaceful purposes under the NPT, and further says that it "has constantly complied with its obligations under the NPT and the Statute of the International Atomic Energy Agency". Twelve other countries are known to operate uranium enrichment facilities. Iran states that "the failure of certain Nuclear Weapon States to fulfill their international obligations continue to be a source of threat for the international community". Iran has called for the development of a follow up committee to ensure compliance with global nuclear disarmanent. Iran and many other nations without nuclear weapons have said that the present situation whereby Nuclear Weapon States monopolise the right to possess nuclear weapons is "highly discriminatory", and they have pushed for steps to accelerate the process of nuclear disarmament. Iran has criticized the European Union because it believes it has taken no steps to reduce the danger of nuclear weapons in the Middle East.</blockquote>

On 14 November 2004, Iran's chief nuclear negotiator said that his country agreed to voluntarily and temporarily suspend the uranium enrichment program after pressure from the European Union on behalf of the United Kingdom, France and Germany, as a confidence building measure for a reasonable period of time, with six months mentioned as a reference. Iranian president Mahmoud Ahmadinejad has publicly stated Iran is not developing nuclear weapons. On 9 August 2005 Iran's Supreme Leader, Ayatollah Ali Khamenei, issued a fatwa that the production, stockpiling and use of nuclear weapons are forbidden under Islam and that Iran shall never acquire these weapons. The text of the fatwa has not been released although it was referenced in an official statement at a meeting of the International Atomic Energy Agency (IAEA) in Vienna. Iranian President Mahmoud Ahmadinejad in a 2005 speech to the U. N. General Assembly said "We are concerned that once certain powerful states completely control nuclear energy resources and technology, they will deny access to other states and thus deepen the divide between powerful countries and the rest of the international community peaceful use of nuclear energy without possession of a nuclear fuel cycle is an empty proposition". On 6 August 2005, Iran rejected a 34 page European Union proposal intended to help Iran build "a safe, economically viable and proliferation proof civil nuclear power generation and research program." The Europeans, with US agreement, intended to entice Iran into a binding commitment not to develop uranium enrichment capability by offering to provide fuel and other long term support that would facilitate electricity generation with nuclear energy. Iranian Foreign Ministry spokesman Hamid Reza Asefi rejected the proposal saying, "We had already announced that any plan has to recognize Iran's right to enrich uranium". After the Iranian Revolution, Germany halted construction of the Bushehr reactor, the United States cut off supply of highly enriched uranium (HEU) fuel for the Tehran Research Reactor, and Iran never received uranium from France which it asserted it was entitled to. Russia agreed not to provide an enrichment plant and terminated cooperation on several other nuclear related technologies, including laser isotope separation; China terminated several nuclear projects (in return, in part for entry into force of a U. S. China civil nuclear cooperation agreement); and Ukraine agreed not to provide the turbine for Bushehr. Iran argues that these experiences contribute to a perception that foreign nuclear supplies are potentially subject to being interrupted. Iran resumed its uranium enrichment program in January 2006, prompting the IAEA to refer the issue to the UN Security Council. On 21 February 2006, Rooz, a news website run by Iranian exiles (the Fedayeen Khalq [People's Commandos] leftist terrorist group), reported that Hojatoleslam Mohsen Gharavian, a student of Qom's fundamentalist cleric Mesbah Yazdi, spoke about the necessity of using nuclear weapons as a means to retaliate and announced that "based on religious law, everything depends on our purpose". In an interview with the Islamic Republic News Agency the same day, Gharavian rejected these reports, saying "We do not seek nuclear weapons and the Islamic religion encourages coexistence along with peace and friendship these websites have tried to misquote me." On 11 April 2006, Iranian President Mahmoud Ahmadinejad announced Iranian scientists working at the pilot facility at Natanz had successfully enriched uranium to the 3.5 percent level, using a small cascade of 164 gas centrifuges. In the televised address from the city of Mashhad he said, "I am officially announcing that Iran has joined the group of those countries which have nuclear technology". In May 2006 some members of the Iranian legislature ("Majlis" or Parliament) sent a letter to UN Secretary General Kofi Annan threatening to withdraw from the NPT if Iran's right to peaceful use of nuclear technology under the treaty was not protected. On 21 February 2007, the same day the UN deadline to suspend nuclear activities expired, Mahmoud Ahmadinejad made the following statement: "If they say that we should close down our fuel production facilities to resume talks, we say fine, but those who enter talks with us should also close down their nuclear fuel production activities". The White House's spokesperson Tony Snow rejected the offer and called it a "false offer". Iran has said that U. N. Security Council sanctions aimed at curtailing its uranium enrichment activities unfairly target its medical sector. "We have thousands of patients a month at our hospital alone If we can't help them, some will die. It's as simple as that," said an Iranian nuclear medicine specialist. An Iranian Jew from California claimed "I don't believe in these sanctions They hurt normal people, not leaders. What is the use of that?" Vice President of the Atomic Energy Organization of Iran Ghannadi framed the debate as a humanitarian issue, "This is about human beings. . When someone is sick, we should give medicine." Iran informed the International Atomic Energy Agency (IAEA) that fuel obtained from Argentina in 1993 would run out by the end of 2010, and that it could produce the uranium itself or buy the uranium from abroad. In February 2010, to refuel the Tehran Research Reactor which produces medical isotopes, Iran began using a single cascade to enrich uranium "up to 19.8%", to match the previously foreign supplied fuel. 20% is the upper threshold for low enriched uranium (LEU). Though HEU enriched to levels exceeding 20% is considered technically usable in a nuclear explosive device, this route is much less desirable because far more material is required to achieve a sustained nuclear chain reaction. HEU enriched to 90% and above is most typically used in a weapons development program. In an interview in October 2011, President Ahmadinejad of Iran said: "We have already expressed our views about nuclear bombs. We said those who are seeking to build nuclear bombs or those who stockpile, they are politically and mentally retarded. We think they are stupid because the era of nuclear bombs is over. [Why] for example, should Iran continue its efforts and tolerate all international treasures only to build a nuclear bomb, or a few nuclear bombs that are useless? They can never be used!" On 22 February 2012, in a meeting in Tehran with the director and officials of the Atomic Energy Organization of Iran (AEOI) and nuclear scientists, Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei said: "The Iranian nation has never pursued and will never pursue nuclear weapons. There is no doubt that the decision makers in the countries opposing us know well that Iran is not after nuclear weapons because the Islamic Republic, logically, religiously and theoretically, considers the possession of nuclear weapons a grave sin and believes the proliferation of such weapons is senseless, destructive and dangerous."

[[File:Secretary Blinken Meets with Israeli Alternate Prime Minister and Defense Minister Gantz (51222835918). jpg|thumb|260px|Joe Biden's Secretary of State Antony Blinken did not rule out a military intervention to stop Iran from obtaining nuclear weapons. The IAEA Board of Governors, in a rare divided vote, found Iran in noncompliance with its NPT safeguards agreement for a 1985–2003 "policy of concealment" the IAEA and others consider these technologies to be of particular concern because they can be used to produce fissile material for use in nuclear weapons. The United States has argued that Iran's concealment of efforts to develop sensitive nuclear technology is prima facie evidence of Iran's intention to develop nuclear weapons, or at a minimum to develop a latent nuclear weapons capability. Others have noted that while possession of the technology "contributes to the latency of non nuclear weapon states in their potential to acquire nuclear weapons" but that such latency is not necessarily evidence of intent to proceed toward the acquisition of nuclear weapons, since "intent is in the eye of the beholder". The United States has also provided information to the IAEA on Iranian studies related to weapons design, activities, including the intention of diverting a civilian nuclear energy program to the manufacture of weapons, based on a laptop computer reportedly linked to Iranian weapons programs. The United States has pointed to other information reported by the IAEA, including the Green Salt Project, the possession of a document on manufacturing uranium metal hemispheres, and other links between Iran's military and its nuclear program, as further indications of a military intent to Iran's nuclear program. The IAEA has said U. S. intelligence provided to it through 2007 has proven inaccurate or not led to significant discoveries inside Iran; however, the US, and others have recently provided more intelligence to the agency. In May 2003, The Swiss ambassador to Iran sent the State Department a two page document, reportedly approved by Ayatollah Khamanei, outlining a road map towards normalization of relations between the two states. The Iranians offered full transparency of its nuclear programme and withdrawal of support from Hamas and Hezbollah in exchange for security assurances and normalization of diplomatic relations. The Bush Administration did not respond to the proposal, as senior U. S. officials doubted its authenticity. The United States acknowledges Iran's right to nuclear power, and has joined with the EU 3, Russia and China in offering nuclear and other economic and technological cooperation with Iran if it suspends uranium enrichment. This cooperation would include an assured supply of fuel for Iran's nuclear reactors. A potential reason behind U. S. resistance to an Iranian nuclear program lies in Middle Eastern geopolitics. In essence, the US feels that it must guard against even the possibility of Iran obtaining a nuclear weapons capability. Some nuclear technology is dual use; i. e. it can be used for peaceful energy generation, and to develop nuclear weapons, a situation that resulted in India's nuclear weapons program in the 1960s. A nuclear armed Iran would dramatically change the balance of power in the Middle East, weakening US influence. It could also encourage other Middle Eastern nations to develop nuclear weapons of their own further reducing US influence in a critical region. In 2003, the United States insisted that Tehran be "held accountable" for seeking to build nuclear arms in violation of its agreements. In June 2005, the US secretary of state Condoleezza Rice required former IAEA head Mohamed ElBaradei to either "toughen his stance on Iran" or fail to be chosen for a third term as IAEA head. The IAEA has on some occasions criticised the stance of the U. S. on Iran's program. The United States denounced Iran's successful enrichment of uranium to fuel grade in April 2006, with spokesman Scott McClellan saying, they "continue to show that Iran is moving in the wrong direction". In November 2006, Seymour Hersh described a classified draft assessment by the Central Intelligence Agency "challenging the White House's assumptions about how close Iran might be to building a nuclear bomb." He continued, "The CIA found no conclusive evidence, as yet, of a secret Iranian nuclear weapons program running parallel to the civilian operations that Iran has declared to the International Atomic Energy Agency," adding that a current senior intelligence official confirmed the assessment. On 25 February 2007, The Daily Telegraph reported that the United States Fifth Fleet, including the Nimitz class supercarriers Eisenhower, Nimitz and Stennis "prepares to take on Iran". In March 2006, it was reported that the US State Department had opened an Office of Iranian Affairs (OIA) – overseen by Elizabeth Cheney, the daughter of Vice President Dick Cheney. The office's mission was reportedly to promote a democratic transition in Iran. and to help "defeat" the Iranian regime. Iran argued the office was tasked with drawing up plans to overthrow its government. One Iranian reformer said after the office opened that many "partners are simply too afraid to work with us anymore", and that the office had "a chilling effect". The US Congress has reportedly appropriated more than $120 million to fund the project. The Bush Administration repeatedly refused to rule out use of nuclear weapons against Iran. The U. S. Nuclear Posture Review made public in 2002 specifically envisioned the use of nuclear weapons on a first strike basis, even against non nuclear armed states. Investigative reporter Seymour Hersh reported in 2006 that the Bush administration had been planning the use of nuclear weapons against Iran. When specifically questioned about the potential use of nuclear weapons against Iran, President Bush claimed that "All options were on the table." According to the Bulletin of the Atomic Scientists, "the president of the United States directly threatened Iran with a preemptive nuclear strike. It is hard to read his reply in any other way." In September 2007, Condoleezza Rice, U. S. Secretary of State, cautioned the IAEA not to interfere with international diplomacy over Iran's alleged weapons program. She said the IAEA's role should be limited to carrying out inspections and offering a "clear declaration and clear reporting on what the Iranians are doing; whether and when and if they are living up to the agreements they have signed." Former IAEA Director General ElBaradei called for less emphasis on additional UN sanctions and more emphasis on enhanced cooperation between the IAEA and Tehran. Iran has agreed with IAEA requests to answer unresolved questions about its nuclear program. ElBaradei often criticized what he called "war mongering," only to be told by Rice to mind his business. In December 2007, the United States National Intelligence Estimate (which represents the consensus view of all 16 American spy agencies) concluded, with a "high level of confidence", that Iran had halted all of its nuclear weapons program in 2003 and that the program remains frozen. The new estimate says that the enrichment program could still provide Iran with enough raw material to produce a nuclear weapon sometime by the middle of next decade but that intelligence agencies "do not know whether it currently intends to develop nuclear weapons" at some future date. Senator Harry Reid, the majority leader, said he hoped the administration would "appropriately adjust its rhetoric and policy". Iran's President Mahmoud Ahmadinejad described the successful launching of the Omid data processing satellite as a very big source of pride for Iran and said the project improved Iran's status in the world. The United States claimed Iran's activities could be linked to the development of a military nuclear capability and that the activities were of "great concern". The U. S. specifically said it would continue "to address the threats posed by Iran, including those related to its missile and nuclear programs." Despite the U. S. saying it would use all elements of its national power to deal with Tehran's actions, Iran said the launch was a step to remove the scientific monopoly certain world countries are trying to impose on the world. Iraqi National Security Advisor Muwafaq al Rubaie said Iraq was very pleased with the launch of Iran's peaceful data processing national satellite. In March 2009, Richard N. Haass, President of the Council on Foreign Relations, wrote that U. S. policy must be thoroughly multilateral and suggested recognizing Iranian enrichment while getting Iran to agree to limits on its enrichment. "In return, some of the current sanctions in place would be suspended. In addition, Iran should be offered assured access to adequate supplies of nuclear fuel for the purpose of producing electricity. Normalization of political ties could be part of the equation," Haass said. In October 2009, Ploughshares Fund President Joseph Cirincione outlined "five persistent myths about Iran's nuclear program": that Iran is on the verge of developing a nuclear weapon, that a military strike would knock out Iran's program, that "we can cripple Iran with sanctions", that a new government in Iran would abandon the nuclear program, and that Iran is the main nuclear threat in the Middle East. In 2009, Independent U. S. Security Consultant Linton F. Brooks wrote that in an ideal future "Iran has abandoned its plans for nuclear weapons due to consistent international pressure under joint U. S.–Russian leadership. Iran has implemented the Additional Protocol and developed commercial nuclear power under strict International Atomic Energy Agency (IAEA) safeguards using a fuel leasing approach with fuel supplied by Russia and spent fuel returned to Russia." A 2009 U. S. congressional research paper says U. S. intelligence believes Iran ended "nuclear weapon design and weaponization work" in 2003. while other "top advisers" in the Obama administration "say they no longer believe the key finding of the 2007 National Intelligence Estimate". Thomas Fingar, former Chairman of the National Intelligence Council until December 2008, said that the original 2007 National Intelligence Estimate on Iran "became contentious, in part, because the White House instructed the Intelligence Community to release an unclassified version of the report's key judgments but declined to take responsibility for ordering its release." Lieutenant General Ronald Burgess, the chief of the Defense Intelligence Agency, said in January 2010 that there is no evidence that Iran has made a decision to build a nuclear weapon and that the key findings of a 2007 National Intelligence Estimate are all still correct. On 20 July 2011, Frederick Fleitz, a former CIA analyst and House Intelligence Committee staff member, took issue with a February 2011 revision of the 2007 National Intelligence Estimate on Iran's nuclear weapons program in a Wall Street Journal op ed titled "America's Intelligence Denial on Iran." In the op ed, Fleitz claimed the new estimate had serious problems and underplayed the threat from Iran's pursuit of nuclear weapons program much as the 2007 version did. However, Fleitz stated that he was not permitted by CIA censors to discuss his specific concerns about the estimate. Fleitz also claimed the estimate had a four member outside review board that he viewed as biased since three of the reviewers held the same ideological and political views and two of them were from the same Washington DC think tank. He noted that the CIA prevented him from releasing the names of the outside reviewers of the 2011 Iran estimate. Several high U. S. military and intelligence officials have stated that the effects of an Israeli attack on Iran's nuclear facilities would not be preventive. Defense Secretary Leon E. Panetta said in December 2011, and Lt. Gen. James R. Clapper, director of National Intelligence, said in February 2012 that an Israeli attack would only delay Iran's program by one or two years. General Michael V. Hayden, former CIA Director, said in January 2012 that Israel was not able to inflict significant damage on Iran's nuclear sites. He said, "They only have the ability to make this worse." In February 2012, Admiral William J. Fallon, who retired in 2008 as head of U. S. Central Command, said, "No one that I'm aware of thinks that there's any real positive outcome of a military strike or some kind of conflict." He advocated negotiating with Iran and deterring Iran from aggressive actions and said, "Let's not precipitate something." General Martin Dempsey, Chairman of the Joint Chiefs of Staff, said in August 2012 that a unilateral Israeli attack on Iran would delay but not destroy Iran's nuclear program and that he did not wish to be "complicit" in such an attack. He also stated that sanctions were having an effect and should be given time to work, and that a premature attack might damage the 'international coalition' against Iran. Former Defense Secretary and former CIA Director Robert Gates stated in October 2012 that sanctions were beginning to have an effect and that "the results of an American or Israeli military strike on Iran could, in my view, prove catastrophic, haunting us for generations in that part of the world." In 2011, the senior officers of all of the major American intelligence agencies stated that there was no conclusive evidence that Iran has made any attempt to produce nuclear weapons since 2003. In June 2023, an assessment by the U. S. Director of National Intelligence concluded that Iran was not developing nuclear weapons, though it was improving its nuclear capabilities, reporting that "Iran is not currently undertaking the key nuclear weapons development activities that would be necessary to produce a testable nuclear device".

In 2009, the United Nations built a seismic monitoring station in Turkmenistan near its border with Iran, to detect tremors from nuclear explosions. The UN Security Council has demanded Iran freeze all forms of uranium enrichment. An intelligence report from an unknown country alleged that rogue employees of Kazakhstan were prepared to sell Iran 1,350 tons of purified uranium ore in violation of UN Security Council sanctions. Russia said it had no knowledge of an alleged Iranian plan to import purified uranium ore from Kazakhstan. Kazakhstan denied the reports. "Such fabrications of news are part of the psychological warfare (against Iran) to serve the political interests of the hegemonic powers," Iran said. Askar Abdrahmanov, the official representative of the Ministry for Foreign Affairs of Kazakhstan, said "the references to the anonymous sources and unknown documents show groundlessness of these insinuations."

The Chinese Foreign Ministry supports the peaceful resolution of the Iran nuclear issue through diplomacy and negotiations. In May 2006 Chinese Foreign Ministry spokesperson Liu Jianchao stated "As a signatory to the Non Proliferation Treaty, Iran enjoys the right to peaceful use of nuclear power, but it should also fulfil its corresponding responsibility and commitment". He added "It is urgently needed that Iran should fully cooperate with the IAEA and regain the confidence of the international community in its nuclear program". In April 2008, several news agencies reported that China had supplied the IAEA with intelligence on Iran's nuclear program following a report by Associated Press reporter George Jahn based on anonymous diplomatic sources. In January 2010, China reiterated its calls for diplomatic efforts on the Iran nuclear issue over sanctions. "Dialogue and negotiations are the right ways of properly solving the Iran nuclear issue, and there is still room for diplomatic efforts," said Chinese spokesperson Jiang Yu. "We hope the relevant parties take more flexible and pragmatic measures and step up diplomatic efforts in a bid to resume talks as soon as possible," said Jiang. In September 2011 Israeli newspaper Haaretz reported several statements about Iran's nuclear program and China's foreign policy in the Middle East, made by independent Chinese expert on the Middle East who recently visited Israel at the invitation of "Signal", an organization that furthers academic ties between Israel and China. Yin Gang of the Chinese Academy of Social Sciences has expressed his opinion on China policies toward region, and according to Haaretz he made surprising statement: "China is opposed to any military action against Iran that would damage regional stability and interfere with the flow of oil. But China will not stop Israel if it decides to attack Iran. For all these reasons, Israel and the Middle East need a country like China. Israel needs China's power." In March 2012, Chinese Foreign Minister Yang Jiechi said that "China is opposed to any country in the Middle East, including Iran, developing and possessing nuclear weapons. ", adding that Iran nonetheless has the right to pursue nuclear activities for peaceful purposes.

On 16 February 2006 French Foreign Minister Philippe Douste Blazy said "No civilian nuclear programme can explain the Iranian nuclear programme. It is a clandestine military nuclear programme." In January 2007, former French President Jacques Chirac, speaking "off the record" to reporters from The New York Times, indicated that if Iran possessed a nuclear weapon, the weapon could not be used. Chirac alluded to mutually assured destruction when he stated:
"Where will it drop it, this bomb? On Israel? It would not have gone 200 meters into the atmosphere before Tehran would be razed."

In 2005, Russian Advisor to Minister of Atomic Energy Lev Ryabev asserted that "neither the signing by Iran of the NPT, the adoption of the Additional Protocol (which provides for the right of inspection of any facility at any time with no prior notice), placement of nuclear facilities under IAEA safeguards, nor Russia's and Iran's commitments to repatriate spent nuclear fuel to Russia is seen as a good enough argument by the United States." Ryabev argued that "at the same time, such requirements are not imposed on, for example, Brazil, which has been developing its nuclear power industry and nuclear fuel cycle, including uranium enrichment." On 5 December 2007 Russian Foreign Minister Sergey Lavrov said he had seen no evidence of any nuclear weapons program in Iran, no matter how old. On 16 October 2007 Vladimir Putin visited Tehran, Iran to participate in the Second Caspian Summit, where he met with Iranian leader Mahmoud Ahmadinejad. At a press conference after the summit Putin said that "Iran has the right to develop their peaceful nuclear programs without any restrictions". In 2009, Russian Major General Pavel S. Zolotarev argued Iran's security could be partially be assured by supplying Iran with modern missile and air defense systems and offering for Iran to take part in the work of one of the data exchange centers in exchange for "concrete non proliferation obligations". In May 2009, the EastWest Institute released a joint U. S. Russian Threat Assessment on Iran's Nuclear and Missile Potential. The report concluded that there was "no IRBM/ICBM threat from Iran and that such a threat, even if it were to emerge, is not imminent." The report said there was no specific evidence that Iran was seeking the ability to attack Europe and that "it is indeed difficult to imagine the circumstances in which Iran would do so." The report said if Iran did pursue this capability, it would need six to eight years to develop a missile capable of carrying a 1,000 kilogram warhead 2,000 kilometers. The report said Iran ending "IAEA containment and surveillance of the nuclear material and all installed cascades at the Fuel Enrichment Plan" might serve as an early warning of Iranian intentions. Yevgeny Primakov, a former Russian prime minister considered the doyen of Moscow's Middle East experts, said he did "not believe that Iran had made a decision to acquire nuclear weapons. Russia has no concrete information that Iran is planning to construct a weapon. It may be more like Japan, which has nuclear readiness but does not have a bomb," Primakov said.

Israel, which is not a party to the Nuclear Non Proliferation Treaty and which is widely believed to possess nuclear weapons, has frequently claimed that Iran is actively pursuing a nuclear weapons program. Arguing an "existential threat from Iran", Israel has issued several veiled and explicit threats to attack Iran. Mike Mullen, former chairman of the U. S. Joint Chiefs of Staff, has cautioned that an Israeli air attack on Iran would be high risk and warned against Israel striking Iran. George Friedman, head of the global intelligence company Stratfor, has said Iran is "decades away" from developing any credible nuclear arms capacity and that an attack on Iran would have grave repercussions for the global economy. Walter Pincus of the Washington Post has written that Israel's stance on nuclear arms complicates efforts against Iran. Gawdat Bahgat of the National Defense University believes Iran's nuclear program is partially formed on the potential threat of a nuclear Israel. The UN Security Council has also pushed for a nuclear weapon free zone in the Middle East, and has urged all countries to sign and adhere the 1970 Nuclear Nonproliferation Treaty. In May 2010, Israel reportedly deployed Dolphin class submarines with nuclear missiles capable of reaching any target in Iran in the Persian Gulf. Their reported missions were to deter Iran, gather intelligence, and to potentially land Mossad agents on the Iranian coast. In 2018, the Israeli Prime Minister said that the Mossad seized about one hundred thousand documents of Iran's nuclear program.

According to a Dutch newspaper, the Netherlands had launched an operation to infiltrate and sabotage the Iranian weapons industry, but ended the operation due to increasing fears of an American or Israeli attack on Iran's nuclear facilities.

A declaration signed on 20 June 2006 by the foreign ministers of 56 nations of the 57 member Organisation of the Islamic Conference stated that "the only way to resolve Iran's nuclear issue is to resume negotiations without any preconditions and to enhance co operation with the involvement of all relevant parties".

31 July 2006: The UN Security Council gives until 31 August 2006 for Iran to suspend all uranium enrichment and related activities or face the prospect of sanctions. The draft passed by a vote of 14–1 (Qatar, which represents Arab states on the council, opposing). The same day, Iran's U. N. Ambassador Javad Zarif qualified the resolution as "arbitrary" and illegal because the NTP protocol explicitly guarantees under international law Iran's right to pursue nuclear activities for peaceful purposes. In response to today's vote at the UN, Iranian President Mahmoud Ahmadinejad said that his country will revise his position vis à vis the economic/incentive package offered previously by the G 6 (5 permanent Security council members plus Germany.) In December 2006, the Gulf Cooperation Council called for a nuclear weapons free Middle East and recognition of the right of a country to expertise in the field of nuclear energy for peaceful purposes.

The Non Aligned Movement has said that the present situation whereby Nuclear Weapon States monopolise the right to possess nuclear weapons is "highly discriminatory", and they have pushed for steps to accelerate the process of nuclear disarmament. That is a clear majority of the 192 countries comprising the entire United Nations, which comprise 55% of the world population. On 11 September 2007 the Non Aligned Movement rejected any "interference" in Iran's nuclear transparency deal with U. N. inspectors by Western countries through the UN Security Council. On 30 July 2008 the Non Aligned Movement welcomed the continuing cooperation of Iran with the IAEA and reaffirmed Iran's right to the peaceful uses of nuclear technology. The movement further called for the establishment of a nuclear weapons free zone in the Middle East and called for a comprehensive multilaterally negotiated instrument which prohibits threats of attacks on nuclear facilities devoted to peaceful uses of nuclear energy.

Iran ratified the Biological Weapons Convention on 22 August 1973. Iran has advanced biology and genetic engineering research programs supporting an industry that produces world class vaccines for both domestic use and export. The dual use nature of these facilities means that Iran, like any country with advanced biological research programs, could easily produce biological warfare agents. A 2005 report from the United States Department of State claimed that Iran began work on offensive biological weapons during the Iran–Iraq War, and that their large legitimate bio technological and bio medical industry "could easily hide pilot to industrial scale production capabilities for a potential BW program, and could mask procurement of BW related process equipment". The report further said that "available information about Iranian activities indicates a maturing offensive program with a rapidly evolving capability that may soon include the ability to deliver these weapons by a variety of means". According to the Nuclear Threat Initiative, Iran is known to possess cultures of the many biological agents for legitimate scientific purposes which have been weaponised by other nations in the past, or could theoretically be weaponised. Although they do not allege that Iran has attempted to weaponise them, Iran possesses sufficient biological facilities to potentially do so.

thumb|300px|Iranian soldier with gas mask under chemical bombardment by Iraqi forces in the battlefield during the Iran–Iraq War. Iran has experienced attack by chemical warfare (CW) on the battlefield and suffered hundreds of thousands of casualties, both civilian and military, in such attacks during the 1980–88 Iran–Iraq War. Iran was completely unprepared for chemical warfare and did not even have sufficient gas masks for its troops. Due to sanctions, Iran had to purchase gas masks from North Korea or commercial painting respirator masks bought from the West. Iran is not known to have resorted to using chemical weapons in retaliation for Iraqi chemical weapons attacks during the Iran–Iraq War despite the fact it would have been legally entitled to do so under the then existing international treaties on the use of chemical weapons which only prohibited the first use of such weapons. Still Iran did develop a chemical weapons program during the latter part of that war, and in 1989, The New York Times reported that Iran started a major campaign to produce and stockpile chemical weapons after a truce was agreed with Iraq. On 13 January 1993 Iran signed the Chemical Weapons Convention and ratified it on 3 November 1997. In the official declaration submitted to OPCW Iranian government acknowledged that it had developed a chemical weapons program in the 1980s but asserted that it had since ceased the program and destroyed the stockpiles of operational weapons. In an interview with Gareth Porter, Mohsen Rafighdoost, the Minister of the Islamic Revolutionary Guard Corps throughout the eight year Iran Iraq war, described how supreme leader Ayatollah Khomeini had twice blocked his proposal to begin working on both nuclear and chemical weapons to counter Iraqi chemical attacks, which Rafighdoost interpreted as a fatwa against their use and production, because it was issued by the "guardian jurist". A U. S. Central Intelligence Agency report dated January 2001 speculated that Iran had manufactured and stockpiled chemical weapons – including blister, blood, choking, and probably nerve agents, and the bombs and artillery shells to deliver them. It further claimed that during the first half of 2001, Iran continued to seek production technology, training, expertise, equipment, and chemicals from entities in Russia and China that could be used to help Iran reach its goal of having indigenous nerve agent production capability. However the certainty of this assessment declined and in 2007 the U. S. Defense Intelligence Agency limited its public assessment to just noting that "Iran has a large and growing commercial chemical industry that could be used to support a chemical agent mobilization capability." Iran is a signatory of the Chemical Weapons Convention, which bans chemical weapons, delivery systems, and production facilities. Iran has reiterated its commitment to the CWC and its full support for the work of the OPCW, in particular in view of the considerable suffering these weapons have caused to the Iranian people. Iran has not made any declaration of a weapons stockpile under the treaty. In 2013 Ahmet Uzumcu, the Director General of the OPCW, hailed Iran as an effective and active member state of the OPCW. In 2016 Iranian chemists synthesised five Novichok nerve agents, originally developed in the Soviet Union, for analysis and produced detailed mass spectral data which was added to the OPCW Central Analytical Database. Previously there had been no detailed descriptions of their spectral properties in open scientific literature.

Any aircraft could potentially be used to host some form of WMD distribution system. Iran has a varied air force with aircraft purchased from many countries, including the United States. Due to sanctions, the Iranian government has encouraged the domestic production of aircraft and, since 2002, has built its own transport aircraft, fighters, and gunship helicopters.
