Iran closes in on a nuclear weapon

Wednesday - 3/16/2011, 7:33pm EDT

The State Department's senior adviser for non-proliferation and arms control says Iran is approaching the capability to produce nuclear weapons. Robert Einhorn told the Arms Control Association yesterday in his own words, "We believe that at a minimum Iran is moving to the threshold of a nuclear weapons capability." But he clarified that he was referring to their intentions rather than their actual capabilities. Some have speculated Iran could reach the point where it could produce a nuke this year.
