Warnings in the Weapons Annex to the IAEA Report of November 8, 2011 Iran’s potential acquisition of nuclear weapons and the ability to arm its missiles and aircraft with such weapons represents the most serious risk that shapes US, Arab, Israeli and other international perceptions. It is an area in which the exact details of threat perceptions are particularly critical, although many key aspects of Israeli, US, and Gulf perceptions – as well as the perceptions of the decision makers in other states – are again impossible to determine at an unclassified level. The new IAEA report issued on November 8, 2011 highlights both the evident and the uncertainties involved. Reports by groups like ISIS describe what the new IAEA report says about Iran’s near term capability to manufacture nuclear weapons in detail. Some of the key point in the new IAEA report do, however, provide a broad warning about Iran’s actions and intentions: Non-Compliance on Enrichment and Research Activity Once again, Iran is failing to comply with its obligations under the Nuclear Non-proliferation Treaty (NPT). The IAEA report states that: The Agency is still awaiting a substantive response from Iran to Agency requests for further information in relation to announcements made by Iran concerning the construction of ten new uranium enrichment facilities, the sites for five of which, according to Iran, have been decided, and the construction of one of which was to have begun by the end of the last Iranian year (20 March 2011) or the start of this Iranian year. In August 2011, Dr. Abbasi was reported as having said that Iran did not need to build new enrichment facilities during the next two years. Iran has not provided information, as requested by the Agency in its letter of 18 August 2010, in connection with its announcement on 7 February 2010 that it possessed laser enrichment technology.
