Lt. Gen John Allen will succeed Gen Petraeus in leading the war effort in Afghanistan. Allen was the deputy commander in Anbar province, Iraq, from 2006-2008. He backed Colonel Sean MacFarland's efforts to get Sunni tribal leaders to join the U.S. against Al Quaeda militants- which came to be called the Sunni Awakening. Allen is close to Gen. Petraeus and has the skills and diplomacy that Petraeus is known for. He is described as someone who understands that the war in Afghanistan involves policy, politics, perceptions and diplomacy.
