Since the attempted underwear bombing of 2009, al Qaeda in the Arabian Peninsula has not been accused of trying to attack the United States.

He admits his strategy is "not neat and not simple," but he calls it "the best option we have." After last week's collapse of a sympathetic Yemini government, is that still true?
