I'm a big believer in remaining open to the possibility that one's basic assumptions are wrong, so I certainly never exclude the possibility that over time I'll change my approach to a particular issue. But if someone told me that between, say, Richard Perle and myself, one would go to his deathbed believing that his support for the Iraq War was right, whereas the other would eventually conclude that he had made a mistake, I'd actually put my money on Richard Perle being the latter. I mean that as no insult to Richard Perle or compliment to myself, or vice versa.
