Afghanistan's Minister of Defense Abdul Rahim Wardak (R) greets United States Secretary of Defense Leon Panetta in Kabul March 15, 2012. Panetta arrived for his unannounced visit three days after a U.S. soldier was accused of shooting dead 16 Afghan civilians, as Washington attempted to calm seething anger over a massacre that raised serious questions about the West's war strategy. Although Panetta's trip was planned before the shooting, it comes as Afghan civilians and lawmakers alike demand answers. REUTERS/Scott Olson/Pool (AFGHANISTAN - Tags: POLITICS MILITARY)
