Yeah, I still wonder...here is an interesting theory:
But the real motivation for the war in Iraq, . . . was the consolidation of Republican power here at home. Iraq was to be George W. Bush's great victory, and Karl Rove's hammer. The victory of the Republican right was to be complete and permanent. Bush and his crew knew the WMD excuse was fraudulent. As Zinni said, he knew, and they had the same information he had. But they did believe the old stockpiles, or some portion of them, were still there, moldering in Saddam's secret bunkers, and would provide all the evidence needed to justify their war, cover their lies, and secure their political triumph. The shame of the election of 2000 would be history, Bush would become the image of the man he always wished to be, and Rove would secure the Republican realignment.

We are betrayed, not by our faults, but by our strengths. Because that's where we're truly blind. Thus you. And me. And Bush. The difference is of degree, not kind. But that difference of degree is crucial. Bush doubts nothing. He is trapped in a rigid arrogance, a self-righteousness based ultimately on low self-esteem and fear of failure. Fear is his basic spiritual signature.

But there is one great dividing line here, between you and me on one side, and Bush and his cohort (and the Christianists and the Islamists and the scientific reductionists, and all the other -ists) on the other: the humility of a faith based on love, with its attendant qualities of acceptance, inclusion and non-violence, and the arrogance of a faith based on fear, with its attendant qualities of judgment, exclusion and, inevitably, violence. . . . I truly believe this division marks the great spiritual, social and political challenge before us in the 21st century: the shift from a faith - and a world - based on the fear of God to one based on the love of God. That is an evolutionary challenge. And a global challenge. And I think that some day it will be recognized as the great theme being played out at the center of the Bush Presidency, and the American tragedy in Iraq. Fear and lies, or love and truth. It's just that simple.
