Netanyahu: Iran Just Six Months from an A-Bomb

That rattling sound you hear? Those are sabers.

Israeli Prime Minister Benjamin Netanyahu warned on Sunday that Iran was just six to seven months away from being able to build a nuclear bomb, adding urgency to his demand that President Barack Obama set a clear "red line" for Tehran in what could deepen the worst U.S.-Israeli rift in decades.

Taking to the television airwaves to make his case directly to the American public, Netanyahu said that by mid-2013 Iran would be 90 percent of the way toward enough enriched uranium for a weapon. He again urged the United States to spell out limits that Tehran must not cross if it is to avoid military action - something Obama has refused to do.
