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. In November 2009, the IAEA Board of Governors adopted 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, and expressed "serious concern" that Iran had not cooperated on issues that needed "to be clarified to exclude the possibility of military dimensions to Iran's nuclear program." Iran said the "hasty and undue" resolution would "jeopardize the conducive environment vitally needed" for successful negotiations. Nuclear weapons Overview In September 2005, the IAEA Board of Governors, in a rare non-consensus decision with 12 abstentions, 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." Iran has claimed that the military threat posed by Israel and the United States is forcing it to restrict the release of information on its nuclear 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 23 December 2006, the Security Council imposed sanctions against Iran, which were tightened on 24 March 2007, because Iran refused to suspend enrichment. Iran's representative to the UN argued that the sanctions compelled Iran to abandon its rights under the NPT to peaceful nuclear technology. The Non-Aligned Movement called on both sides to work through the IAEA for a solution. US intelligence predicted in August 2005 that Iran could have the key ingredients for a nuclear weapon by 2015. On 25 October 2007, the United States declared the Revolutionary Guards a "proliferator of weapons of mass destruction", and the Quds Force
