There's too much political hay to be made undercutting the war, and the consequences be damned. If they want to defeat the war to defeat Bush, well, noted. If they truly believe that the United States is in the same group as the Nazis, the Soviets and Pol Pot, then they've shown they have no perspective, no judgment, no sense of nuance, shall we say. And the idea that such comparisons might be picked up in the Middle East and broadcast with glee is irrelevant; they're parochial to a fault, and care little for anything beyond their reputation and power in Washington.
