Bush only did the wrong thing in your opinion. he actually did the right thing in many peoples opinion including mine. Harper went and apologized for the Canadians that were appaulled by the fact that we did nothing to support out allies in Iraq and fight in a war to bring down a horrible monster.
He went in and took away power from a mass murder who had no concern for human life other then his own.
You really think that given the opportunity Saddam wouldn't attack the US in some manner, whether it be a direct attack, a terrorist attack or any other manner?
