George W. Bush's war in Iraq may not be going as planned. But for those who've stopped believing the myth that prewar Iraq represented any sort of threat to the United States, there is plenty of circumstantial evidence mounting that the real reason for the American invasion of Iraq was the most obvious one: Oil. In this case, "oil" doesn't mean that we went to war for the commercial benefit of US oil companies-and in fact, as I reported in Mother Jones magazine in early 2003, before the war, most US oil firms and their executives were against the war.
