I am sad. Robert Wright may have finally persuaded me that missile defense is unnecessary. September eleventh was a graphic illustration of his contention that missiles from hostile states are not the greatest threat. Attacks from hostile individuals are. I still contend that just because nation-states are not the only threat doesn't mean they can be ignored. Large armies provide no real defense against scattered terrorists and we should probably not build larger armies to fight them, but missile defense could be part of a strategy to prevent other nations from taking advantage of our smaller military. More missiles and fewer men? Mind you this defense is only because I like missile defense. I just hate being wrong and conceding defeat to a liberal like Robert Wright!
