CIA Finds no Evidence of Secret Iranian nuclear-weapons program

The Administration’s planning for a military attack on Iran was made far more complicated earlier this fall by a highly classified draft assessment by the C.I.A. challenging the White House’s assumptions about how close Iran might be to building a nuclear bomb. The C.I.A. found no conclusive evidence, as yet, of a secret Iranian nuclear-weapons program running parallel to the civilian operations that Iran has declared to the International Atomic Energy Agency. (The C.I.A. declined to comment on this story.)

The C.I.A.’s analysis, which has been circulated to other agencies for comment, was based on technical intelligence collected by overhead satellites, and on other empirical evidence, such as measurements of the radioactivity of water samples and smoke plumes from factories and power plants. Additional data have been gathered, intelligence sources told me, by high-tech (and highly classified) radioactivity-detection devices that clandestine American and Israeli agents placed near suspected nuclear-weapons facilities inside Iran in the past year or so. No significant amounts of radioactivity were found.
