US sees Iran's leaders split on nukes

WASHINGTON — US intelligence agencies believe Iran's  leaders are divided over the question of whether to use its nuclear program to develop atomic weapons and is immersed in a serious internal debate about how to proceed in the face of international sanctions, American officials said Wednesday.
"We continue to assess Iran is keeping the option open to develop nuclear weapons in part by developing various nuclear capabilities that better position it to produce such weapons should it choose to do so," National Intelligence Director James Clapper told Congress. "We do not know, however, if Iran will eventually decide to build nuclear weapons."
