Iran heats up foreign policy talk on campaign trail

WASHINGTON - Foreign policy, mostly an afterthought in the presidential contest so far, is emerging as a focal point between President Obama and his Republican challengers - and no issue has more potential to be a game-changer than Iran’s development of a nuclear program, according to several specialists.

Tensions over Iran’s alleged efforts to develop a nuclear bomb are escalating, with the United States and Europe tightening sanctions on Iran’s oil exports and financial institutions and Iran, in turn, threatening to shut down the strategically vital Strait of Hormuz. Intensifying fears are reports that Israel is considering launching a preemptive strike against Iran.
