Greg Djerejian at Belgravia Dispatch, an extraordinarily well-informed and smart dude, links to an article in which Peter Bergen, apparently pretty smart and informed in his own right, has done a masterful job of obliterating the myth that we've abandoned ship in Afghanistan. Read it and love it, and them, and me for showing it/them to you.
As far as I can tell, we've never stopped running ops in Afghanistan, and I'll believe Osama Bin Laden's still alive when anyone can produce better evidence than a years-old bad audiotape. Frankly I could fake better evidence than has been found of his existence. Even if he were still alive, "we let the real bad guy get away" is Michael Moore nonsense. Read all of it, especially Greg's analysis.
