As Barack Obama goes through one of his most difficult periods as president, you might wonder what it would have been like if the other guy had won. We will never know, of course, but in one area, John McCain provides us with some clues. He would have tried to overthrow the government of Iran. In a speech on June 10, later published as a cover essay in The New Republic, McCain urged that we "unleash America's full moral power" to topple the Tehran regime. The speech highlights one of the crucial failings of McCain's world view, one in which rhetoric replaces analysis, and fantasy substitutes for foreign policy.
