I write this with sadness because I greatly admire John McCain, a man of intelligence, honor and enormous personal and political courage. I also agree with much of what else he said in that speech in Los Angeles. But in recent years, McCain has turned into a foreign-policy schizophrenic, alternating between neoconservative posturing and realist common sense. His speech reads like it was written by two very different people, each one given an allotment of a few paragraphs on every topic.
