FILE - In this image made from video taken on May 24, 2008, Pakistan's top Taliban leader Baitullah Mehsud, right, talks to the media in Kotkai, a village in the Pakistani tribal area along the Afghan border. Mehsud was killed in a U.S. missile strike on Wednesday Aug. 5, 2009. Recent deaths of militants in Somalia, Indonesia and Pakistan have chipped away at al-Qaida's power base, sapping the terror network of experienced operatives it had been using to train new recruits and wage attacks.
