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." 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.
