"Since 2003, International Atomic Energy Agency (IAEA) inspections of Iran's nuclear program have revealed significant undeclared activities with potential application for nuclear weapons, including uranium enrichment facilities and plutonium separation efforts. Also since 2003, Iran has been negotiating with Germany, France, and the UK (EU-3) for a wide range of assistance in exchange for a halt to such activities. Yet, most evidence indicates that Iran has never completely suspended its enrichment activities, raising the question of whether Iran is buying time to build nuclear weapons. Although the EU-3 are seeking a permanent suspension, Iran insists its suspension is temporary. Ever on the brink of being declared in violation of the Nonproliferation Treaty (NPT), Iran has allowed IAEA inspectors access only when pressed. This report, which is updated as needed, analyzes the significance of the IAEA's findings for a possible Iranian nuclear weapons program."
