[71] Iran's offer to open its uranium enrichment program to foreign private and public participation mirrors suggestions of an IAEA expert committee which was formed to investigate the methods to reduce the risk that sensitive fuel cycle activities could contribute to national nuclear weapons capabilities.
[81][82] Though South Korea's case involved enriching uranium to levels near weapons grade,[83] the country itself voluntarily reported the isolated activity[84] and Goldschmidt has argued "political considerations also played a dominant role in the board's decision" to not make a formal finding of non-compliance.
[125] Majlis speaker Qolam Ali Hadad-adel said on 30 August 2006, that Iran had the right to "peaceful application of nuclear technology and all other officials agree with this decision," according to the semi-official Iranian Students News Agency.
The report stated that the IAEA had "been able to verify the non-diversion of the declared nuclear materials at the enrichment facilities in Iran," and that longstanding issues regarding plutonium experiments and HEU contamination on spent fuel containers were considered "resolved."
[150] A senior IAEA official denied the reports of internal disagreements and accused Western powers of using the same "hype" tactics employed against Iraq before the 2003 US-led invasion to justify imposing further sanctions on Iran over its nuclear program.
The IAEA report stated that Iran had also submitted replies to questions regarding "possible military dimensions" to its nuclear program, which include "alleged studies" on a so-called Green Salt Project, high-explosive testing and missile re-entry vehicles.
[180] In February 2010, the IAEA reported that Iran had failed to explain purchases of sensitive technology as well as secret tests of high-precision detonators and modified designs of missile cones to accommodate larger payloads, experiments closely associated with atomic warheads.
[185] In November 2011, the IAEA reported[186] that inspectors had found credible evidence that Iran had been conducting experiments aimed at designing a nuclear bomb until 2003, and that research may have continued on a smaller scale after that time.
[198] Though Iran was continuing to install thousands of additional centrifuges, these were based on an erratic and outdated design, both in its main enrichment plant at Natanz and in a smaller facility at Fordow buried deep underground.
[202] Peter Crail and Daryl G. Kimball of the Arms Control Association commented that the report "does not identify any breakthroughs" and "confirms initial impressions that Iran's announcements last week on a series of 'nuclear advances' were hyped.
For example, its efforts at mining and converting uranium were announced on national radio,[241][242] and Iran also says that in consultation with the Agency and member states throughout the 1990s it underlined its plans to acquire, for exclusively peaceful purposes, fuel enrichment technology.
[253] Iran also argues that the UN Security Council resolutions demanding a suspension of enrichment constitute a violation of Article IV of the Non-Proliferation Treaty which recognizes the inalienable right of signatory nations to nuclear technology "for peaceful purposes.
In December 2008, President-elect Barack Obama gave an interview on Sunday's "Meet the Press" with host Tom Brokaw during which he said the United States needs to "ratchet up tough but direct diplomacy with Iran".
"[306] A few days later Iranian supreme leader Ayatollah Ali Khamenei rejected the offer and added ambiguously: "The U.S. policies in the Middle East have failed and the Americans are in need of a winning hand.
"[307] On 4 February the Italian news-wire "Agenzia Nova", citing "sources in Teheran," reported that "from the beginning of the year Ali Larijani, Speaker of the (Iranian) Parliament, secretly traveled twice to the United States" to launch direct negotiations with the Obama Administration.
[322] In the lead up to the second round of negotiations in May, and in what may foreshadow a significant concession, an unnamed senior US official hinted the United States might accept Iran enriching uranium to five percent so long as the Iranians agreed to tough international oversight of the process.
[325] The EU's High Representative for Foreign Affairs Catherine Ashton felt compelled to make a special visit to Netanyahu, partly to keep him from again voicing his negativity and opposition to the negotiations.
[331] Iran's nuclear chief, Ali Akbar Salehi, said the site was built for maximum protection from aerial attack: carved into a mountain and near a military compound of the powerful Revolutionary Guard.
"[360] Early analysis from the BBC stated the swap deal could have been an "effort by President Mahmoud Ahmadinejad to deflect pressure for fresh sanctions" and that "Iran watchers are already criticising Washington for moving the goal posts".
[370] On 24 November, the foreign ministers of Iran and the P5+1 agreed to a six-month interim deal that involves the freezing of key parts of the Iranian nuclear program in exchange for a decrease in sanctions, to provide time to negotiate a permanent agreement.
According to reports, the agents came in a truck semitrailer at midnight, cut into dozens of safes with "high intensity torches", and carted out "50,000 pages and 163 compact discs of memos, videos and plans" before leaving in time to make their escape when the guards came for the morning shift at 7 am.
"[412] In March 2022, Iran defied Western powers by turning part of its enriched uranium to near-weapons-grade into a form that is more difficult to retrieve, dilute, and transport out of the country, according to a report released by the United Nations nuclear watchdog.
[418] During a video posted on social media in May 2022, Israeli Prime Minister Naftali Bennett showed a stack of compromising documents stolen by Iran from the IAEA and later obtained by the Mossad during a 2018 raid in a warehouse in Tehran.
The documents in Israel's possession includes what appears to be a request by the then Iranian defense minister to come up with a cover story to hide evidence from the UN's atomic agency in case of inspections.
[424] In September 2022, Germany, United Kingdom and France expressed doubts over Iran's sincerity in returning to the JCPOA after Tehran insisted that the IAEA close its probes into uranium traces at three undeclared Iranian sites.
"[426] United Nations Secretary-General António Guterres urged Iran to hold "serious dialogue" about nuclear inspections and said IAEA's independence is "essential" in response to Iranian demands to end probes.
[427] On 22 October 2022, the Iranian hacktivist group Black Reward leaked 50 gigabytes of internal emails, contracts, and construction plans related to Iran's Bushehr power plant.
Reportedly, Heinonen added that the IAEA had obtained corroborating information from the intelligence agencies of several countries, that pointed to sophisticated research into some key technologies needed to build and deliver a nuclear bomb.
[450] On 30 April 2018, Israeli Prime Minister Benjamin Netanyahu revealed thousands of files he said were copied from a "highly secret location" in Tehran which show an Iranian effort to develop nuclear weapons between 1999 and 2003.
According to US officials, such a crude weapon could be built within months but could not be miniaturized to fit on a ballistic missile and would be less reliable than the more sophisticated designs Iran had considered in the past, which might take a year or more to build.
