How a good vs. evil mentality destroyed the Bush presidency

An excerpt from Glenn Greenwald's book:

In sum, the great and tragic irony of the Bush presidency is that its morally convicted foundations have yielded some of the most morally grotesque acts and radical departures from American values in our country's history. The president who insists that he is driven by a clear and compelling moral framework, in which the forces of Good and Evil battle toward a decisive resolution, has done more than almost any American in history to make the world question on which side of that battle this country is fighting. The more convinced President Bush and his followers become of the unchallengeable righteousness of their cause, the fewer limits they recognize. And America's moral standing in the world, and our national character, continue to erode to previously unthinkable depths.
