The probe has to be formally closed as part of a deal between Iran and six nations to crimp present Iranian nuclear programs that could be used to make such weapons, in exchange for the removal of economic sanctions.
Ahead of adoption of a resolution ending the investigation, Yukiya Amano of the UN's International Atomic Energy Agency told the agency's 35-nation board that his investigation could not "reconstruct all the details of activities conducted by Iran in the past."
Despite Iranian denials, the United States and its allies continue to believe that Tehran did such work. But their overriding interest is moving on to implementing the July 14 deal that focuses on limiting Iran's nuclear activities for more than a decade a plan that depends on shutting down the probe.
An EU statement obtained before delivery reflects the will to move on. Unlike previous statements, it avoids criticism of Iran over its alleged weapons research and development program, saying only "we note" the IAEA conclusion.
Once approved, it opens the way for implementation of that deal, formally expected next month. Once the IAEA confirms that Iran has modified or cut back on programs and activities that could be re-engineered to produce the fissile core of nuclear weapons, individual and international sanctions imposed on Iran over its nuclear program will be lifted.
