Another blow to the 2007 NIE here:
Two years ago, American intelligence agencies published a detailed report concluding that Tehran halted its efforts to design a nuclear weapon in 2003. But in recent months, Britain has joined France, Germany and Israel in disputing that conclusion, saying the work has been resumed.
A senior American official said last week that the United States was now re-evaluating its 2007 conclusions.
The atomic agency’s report also presents evidence that beyond improving upon bomb-making information gathered from rogue nuclear experts around the world, Iran has done extensive research and testing on how to fashion the components of a weapon. It does not say how far that work has progressed.
The report, titled “Possible Military Dimensions of Iran’s Nuclear Program,” was produced in consultation with a range of nuclear weapons experts inside and outside the agency. It draws a picture of a complex program, run by Iran’s Ministry of Defense, “aimed at the development of a nuclear payload to be delivered using the Shahab 3 missile system,” Iran’s medium-range missile, which can strike the Middle East and parts of Europe. The program, according to the report, apparently began in early 2002.
