As recently as mid-August, U.S. officials stood by their assessments that Iran had not resumed a full-scale nuclear weapons program. An Associated Press report today hints that new information says the opposite. Four diplomats to the U.N.'s nuclear watchdog told the AP that
the intelligence shows that Iran has advanced its work on calculating the destructive power of an atomic warhead through a series of computer models that it ran sometime within the past three years.
The U.N. group, the International Atomic Energy Agency, wrote in a report last November that "the modeling studies alleged to have been conducted in 2008 and 2009 by Iran ... (are) of particular concern." The new details seem to flesh out those allegations. The AP said the information came from the U.S., Israel and two other Western countries.
