U.S. Defense Secretary Leon Panetta said on Sunday that Iran is only one year away from producing a nuclear weapon. In an interview on the CBS show "60 Minutes," Panetta said that “the consensus is that, if they decided to do it, it would probably take them about a year to be able to produce a bomb and then possibly another one to two years in order to put it on a deliverable vehicle of some sort in order to deliver that weapon.”
