Supporters of the war have engaged in a vigorous debate, in these pages and elsewhere, about how better to fight this war. It would be encouraging if more people at senior levels of the military seemed to be engaged in this kind of serious thinking and rethinking. It would be encouraging if more civilians high up in the Pentagon were engaged in such a debate. It would be encouraging if a single person in the White House seemed to be engaged in a real effort to learn from mistakes, so as to adjust our policy to make success more likely.
