Petraeus: Greatest threat to U.S. comes from South Asia.

REED: In fact, Admiral Mullen has stated, “If we’re going to pick the next attack on the United States, it would come out the FATA.” Do you agree with those intelligence assessments?

PETRAEUS: I do, Senator. Clearly, al Qaeda’s senior leadership has been strengthened in the FATA, even though their main efforts still is assessed to be in Iraq by them, as well as by us. But the organization of an attack, if you will, would likely come from the FATA.
