How do you sleep?

I find it interesting that the Bush administration has been so critical of the Newsweek article that stated that American interrogators at Guantánamo Bay had flushed a Koran down a toilet. The administration stated:

"...the Newsweek article had damaged the image of the United States abroad. It reflected the severity of consequences that even one sentence in a brief news article can have at a time of intense anti-American sentiment overseas and political polarization, as well as extreme distrust of the mainstream media at home."

In light of this statement, I find it particularly puzzling that the administration hasn't retracted its statements on Weapons of Mass Destruction or backed out of this war. At least Newsweek retracted their account when their source retracted their original statement. Why hasn't Bush done the same? His sources were in error, and I believe it is safe to say that the actions taken by Bush have "damaged the image of the United States abroad" and caused "intense anti-American sentiment overseas", not to mention the loss of hundreds of thousands of innocent lives.

How does George Bush sleep at night?
