At a news conference at the White House on Tuesday, President Obama lashed out at Mitt Romney and the other GOP presidential candidates for "the casualness with which some of these folks talk about war," saying their rhetoric on Iran reflects the fact that they "don't have a lot of responsibilities."

 

The president was asked about Romney's claim that "If Barack Obama gets re-elected, Iran will have a nuclear weapon." He responded first by pointing to his record, saying his administration has imposed "crippling sanctions" against Iran that have isolated the nation in an "unprecedented" way and significantly damaged its government economically.

He went on to say that while "we will not countenance Iran getting a nuclear weapon," he believes that "we have a window of opportunity where this can still be resolved diplomatically."
