One of the clearest differences in the presidential debate Monday night came when each candidate was asked to identify the greatest foreign threat facing the United States.
President Obama said it was terrorism.
Governor Romney said it was a nuclear Iran.
So, who’s right? Or does it really matter, since presumably Romney thinks terrorism is a threat as well (just not as high) and Obama has already said he would take military action, if necessary, to prevent Iran from acquiring nuclear weapons (though Romney has said Obama has been too slow to deal with the threat.)
