Why did George W. Bush invade Iraq? Clive Hamilton confirms one of my suspicions at Alternet:

In 2003 while lobbying leaders to put together the Coalition of the Willing, President Bush spoke to France's President Jacques Chirac. Bush wove a story about how the Biblical creatures Gog and Magog were at work in the Middle East and how they must be defeated. . . President Bush's reason for launching the war in Iraq was, for him, fundamentally religious. He was driven by his belief that the attack on Saddam's Iraq was the fulfilment of a Biblical prophesy in which he had been chosen to serve as the instrument of the Lord.
