Many have charged that President Obama's decision to begin withdrawing from Afghanistan 10 months from now is hampering our war effort. But now it's official. In a stunning statement last week, Marine Corps Commandant James Conway admitted that the July 2011 date is "probably giving our enemy sustenance."

A remarkably bold charge for an active military officer. It stops just short of suggesting aiding and abetting the enemy. Yet the observation is obvious: It is surely harder to prevail in a war that hinges on the allegiance of the locals when they hear the U.S. president talk of beginning a withdrawal that will ultimately leave them to the mercies of the Taliban.
