I think the reason the United States is having such trouble with its strategy in the Middle East is that Iran is playing chess, and the US is playing checkers (poorly, at that).
Once Bush figures this out (if he ever does), he'll find he's in a position where he's going to lose his queen and a bunch of other pieces as well. And though he might inflict some pain on his opponent, he's still going to come out on the sorry end of the volley.
The only way Bush can win at this point is to pick up the game board and toss it across the room (i.e. use nukes). Of course, that will show extremely poor sportsmanship, and no one will want to play with him anymore.
