The Times of London is reporting that Gen. David Petraeus will leave his spot as the head of the U.S. Afghan Command at the end of the year, not that anyone blames him. Petraeus replaced Gen. Stanley McChrystal in the difficult, thankless job in July of 2010 after McChrystal was fired over a Rolling Stone article; a search is apparently already on for a replacement, who would theoretically be overseeing the withdrawal of American troops and thinking a lot about how great it will be when he can retire and maybe play a little golf.
