In short, Obama bet the farm on his prediction that General Petraeus and the American military would fail. He was as spectacularly wrong as John McCain was spectacularly right. But his op-ed somehow twists this history into vindication on the theory that Afghanistan has deteriorated, the Iraq war has been expensive, and Iraq's political leaders "have not reached the political accommodation that was the stated purpose of the surge."
Let's start with the last point. Obama completely fails to acknowledge the remarkable political progress that has resulted from the surge, as manifested by the fact that the country's largest Sunni bloc has rejoined the government, and the U.S. Embassy reports that 15 of the 18 benchmarks of political progress that were set by Congress are now being met. Those benchmarks were set precisely for the purpose of measuring the "political accommodation that was the stated purpose of the surge," yet Obama fails even to mention them.
Still more dishonest is Obama's failure to acknowledge what would have happened if his policy prescription, precipitate withdrawal regardless of military conditions, had been followed: chaos, sectarian violence, possibly genocide, a resurgent al Qaeda in control of part of Iraq, with Iran possibly in control of other areas of the country. This would have been a foreign policy disaster, yet Obama, with vague references to cost and Afghanistan, claims vindication!
By the way, Paul Hodes also said that the Surge was "too little, too late" and doomed to fail. He was wrong.
