At an Iraq summit at Camp David on June 12, 2006, senior vice president at the Center for Strategic and Budgetary Assessments Michael Vickers “distributed a four-page paper maintaining that ‘it is highly unlikely that American forces, even with growing Iraqi security force assistance, will be able to defeat the insurgency within the next 2-3 years.’ Therefore, the United States should shift to ‘an indirect approach,’ withdrawing all but forty thousand troops that would serve as a quick-reaction force supporting Iraqis who would take the lead ‘no later than summer 2008.’ [Secretary of Defense Donald] Rumsfeld, for one, found Vickers’ case ‘to be persuasive.’ ”
