So what? Generals ALWAYS want more troops and presidents often turn them down. Bush turned down his generals early in his administration who wanted more troops in Iraq so did LBJ did when Westmoreland wanted 200,000 more (on top of 500K!) in 1968.
Besides, who elected McChystal as God? He wasn't so God-like when he clumsily covered up the truth about Pat Tillman's death.
Yes, and then Bush listened to General Petraeus and he got his troops and it turned the tides. Bringing up LBJ as justification for Obama not sending more troops. That makes it ok?
IMHO, we have seen the Taliban move in because they know we have a weak President.
