Think tank: path to Iran nuke warhead 2-4 months
None
A think tank that often briefs Congress and other branches of the US government on Iran's nuclear program says Tehran could produce enough weapons-grade uranium to arm a nuclear warhead within two to four months.
But the Institute for Science and International Security says it would need "many additional months" to make a prototype bomb for underground testing and even longer to make a missile warhead. (AP)
