Debate grows over response to Iran’s nuclear attempts

The U.S. and its allies are united in their public concerns about Iran’s secret nuclear ambitions. But The New York Times reports that U.S. and Israeli intelligence agencies disagree on one big point: how far Iran’s attempts to design or acquire a nuclear warhead have come. U.S. officials say that Iran halted work on weapons design in 2003, but Germany, France and Israel think differently. We get the story from New York Times defense correspondent Mark Mazzetti.
