You should hear the MSNBC commentators and Capitol Hill legislators falling all over themselves in lockstep praise of President Obama‘s whacking of Gen. Stanley McCrystal and tapping General David Petraeus to take his place. One guy actually said that Petraeus “can do the job” and “turn it around.” What? Afghanistan is a swamp, a quagmire, the wrong wicket. Eight years there and we haven’t a prayer of suppressing the Taliban or achieving anything else for that matter. All Petraeus can do is manage an exit — Napoleon retreating from Russia.
