Petraeus Faces Confirmation as Top Military Commander in Afghanistan Washington, D.C. 29 June 2010 President Barack Obama announces Gen. David Petraeus (r) will replace Gen. Stanley McChrystal as U.S. Commander in Afghanistan, at the White House, 23 June 2010 Photo: AP President Barack Obama, accompanied by Gen. David Petraeus, announces in the Rose Garden of the White House in Washington, 23 June 23 2010, that Petraeus would replace Gen. Stanley McChrystal U.S. General David Petraeus is facing a confirmation hearing in which lawmakers are expected to back him as head of the Afghan war effort. The hearing comes amid growing doubts about the U.S. strategy to beat back an increasingly bloody Taliban insurgency. The Senate Armed Services Committee Tuesday is questioning Petraeus, who is not expected to face much opposition to his nomination as the new commander of U.S. and NATO forces in Afghanistan. Petraeus is set to replace General Stanley McChrystal, who resigned last week after disparaging remarks he and his aides made about Obama administration officials were published in a magazine article. McChrystal has told the U.S. army that he plans to retire. Petraeus, who has been head of U.S. Central Command, is widely credited for helping turn the war in Iraq around by implementing a counter-insurgency strategy that helped lay the framework for the current effort in Afghanistan. If confirmed, he faces a number of challenges in Afghanistan. Violence there is at an all-time high and the weak Afghan government is plagued by corruption. A U.S. government audit released Monday said a 5-year-old system that evaluates the effectiveness of Afghan security forces is flawed, leading to inaccurate and often inflated estimates on their ability to operate independently. The probe also said establishing independent Afghan security forces has been hampered by corruption and drug abuse among the forces, as well as a lack of qualified international trainers.  In a written response, U.S. Lieutenant General William Caldwell, who is charge of training Afghan security forces, said the inspector general's report is out of date and not accurate. The United States has spent $27 billion training and equipping Afghan security forces. Some information for this report was provided by AP, AFP and Reuters. .
