I never find the time to read like Atrios does, but this seems quite concise and accurate.

The thing is, you repugs knew Chimpy was a creepy idiot, and you rationalized and voted for him anyway. The biggest rationalization, that I remember, was "he'll surround himself with knowledgeable people." Now you see what you've done? The incompetent creep now thinks he's up to the task of "Decidering" on his own. And this is what you get: Shit. Death. Incompetence. Corruption. The loss of several nations. Constitutional crisis. Trillions wasted. Unable to admit a mistake and amend for your ugly behavior, you repug bastards are still cheerleading for the worst (strategic mistake) president in the history of the nation! Your arrogance, hate and cowardice is destoying the US from within.

It's not that the president has some policy initiative in mind whose operational requirements dictate a surge in force levels. Rather, locked in the prison of his own denial he came to the conclusion that he should back an escalation, prompting the current search for a mission.
