Obama is stuck. If he sends 20,000 more troops, conservative will say: he did not send enough troops. If he did not send additional troops, his critics will say that he is abandoning the mission and reversing course when he argued throughout his campaign that the war in Afghanistan is a war of necessity. Obama will not win, and he will be exposed as the a replica of Bush in foreign policy. In fact, if you look at it: Obama deviated very little from the path of Bush-Cheney in defense and national security.
