Iraq, Afghanistan the the Presidential Candidates

With a new poll showing Americans split down the middle on what to do in Iraq, John McCain and Barack Obama went point-counterpoint today on Iraq, Afghanistan and America's role in the world. Obama defended his timetable for troop withdrawal, listing the strain on the military, the worsening situation in Afghanistan and the failure of Iraqi politicians to resolve their differences as proof that the surge did not accomplish what it was supposed to. McCain had a scornful rejoinder, accusing Obama of losing one war while trying to win another. Has Obama adjusted his policies because the surge has reduced violence? Is McCain pursuing "victory" in an unwinnable war? We ask those questions and get some perspective from an Iraqi point of view.
