Bill O'Reilly earned himself a new nickname with his latest appearance on 'Late Show' (Weeknights, 11:35PM ET on CBS). David Letterman proposed the notion that America turned Iraq into a hotbed of terrorism that it wasn't before our invasion.
Then, in a move that clearly surprised him, O'Reilly essentially agreed with him that our going in was a mistake. He supported it initially based on claims there were weapons of mass destruction there, which turned out to be false.
Letterman then decided to seal their moment of agreement with a high five, which O'Reilly was not inclined to do. At one point, he even chastised Letterman. "We're having a good conversation. Sit down," he ordered.
