Tensions continue to rise between Israel and Iran as Iran works to build a nuclear program. Recent sanctions by the United States have not deterred the country, and it's nearly inevitable at this point that Iran will soon have a nuke, says Emory University nuclear proliferation expert Kyle Beardsley. But, he says, don't expect Iran to use it.

"I think that fear of the rather catastrophic scenarios is misplaced," Beardsley explains. "There is very little chance that Iran would ever use [its] nuclear weapons directly against Israel or against targets of the U.S. simply because Iran would suffer greatly from such a behavior and benefit very little."
