How the Iraq situation looks to a poker player

To me it looks like the American's are sitting in a Texas Hold'em game. All the cards have come out, they have called and the other players have raised. The US can either drop (leave Iraq) and let the rest of the players fight it out. They could call (stay on course with the troops they have) or they could raise (increase troop levels) and try and push some players out. They have a lot of their wealth invested in the pot and its their turn.
