Can you lose a war you don’t fight?
: The NY Times has rich and creamy understatement this morning about the defeated anti-war movement trying to figure out what to do next:

Leaders in the movement do not like to focus on the notion that they lost. Yes, they failed to stop the war. Yes, the public has overwhelmingly supported President Bush’s actions. With a swift United States victory over a brutal dictator and fewer casualties than most experts predicted, it is particularly hard for antiwar organizers to argue that their dire forecasts were right.
