Greenwald unpacks justifications for Obama's troop escalation:

 The most bizarre defense of Obama's escalation is also one of the most common:  since he promised during the campaign to escalate in Afghanistan, it's unfair to criticize him for it now -- as though policies which are advocated during a campaign are subsequently immunized from criticism.  For those invoking this defense:  in 2004, Bush ran for re-election by vowing to prosecute the war in Iraq, keep Guantanamo opened, and privatize Social Security.  When he won and then did those things (or tried to), did you refrain from criticizing those policies on the ground that he promised to do them during the campaign?  I highly doubt it.
