In regards to Iraq, he hit the nail on the head. It appears he's learned an important lesson:
Sometimes a President has to do the unpopular thing in order to do the right thing.
Any President who bases his decisions entirely on the opinion polls is basically an empty suit, following the whims of the American people, not leading them. Dubya has never struck me as an empty suit.
I also find it interesting that during tonight's ABC's World News, one commenter made the observation that if the Democratically controlled Congress pulls the rug out from underneath our troops serving in Iraq, they will be remembered for generations for their cowardly act. Somehow I doubt that's what they would want as their legacy.
