Yes, my position on fighting in Iraq has turned 180 degrees from four years ago. I thought then that fighting in Iraq was the best way to defeat Islamist terrorism. After four years of observing it, and its actual empowerment of Islamist terrorism, I've changed my mind. I have openly acknowledged my change many times, have expressed shame and sorrow at my early misjudgment, wrote a book trying to figure out how I could have strayed so far from small-c conservatism in the traumatized wake of 9/11, and am doing my best to figure out the best way forward. If you think I have no credibility now, having been so wrong then, all I can say is: there are plenty of other blogs to read. But as Keynes said, "When the facts change, I change my mind - what do you do, sir?"
