When Henry Kissinger says, "I don't believe [military victory in Iraq] is possible," when Tony Blair agrees with an interviewer that the intervention has been a "disaster" and when the hawkish New Republic tells its readers that it goes without saying that they regret supporting the war, then it starts to become clear that the war is unwinnable.
So what should be done? The worst part about this is that no one knows, and there is no right answer. Every road seems to lead to US embarassment, more Iraqi and coalition deaths, and chaos in the region. I like Joe Biden's idea, but it's not really being taken very seriously. I guess we'll just have to wait to see what the Baker Commission says.
