General Stanley McChrystal has to be canned or President Obama will look like an even bigger wuss. Those are terms — he must to do an Abraham Lincoln upon his own General George McClellan (who was disrespectful to his commander-in-chef). Because McChrystal “and his hard-bitten, smart-aleck aides nuked the president, vice president and other top advisers as wimps, losers and clowns in a Rolling Stone profile meant to polish the general’s image,” as Maureen Dowd puts it in her current column. No third chances, no slaps on the wrist…fire his ass.
