Maybe because everyone followed. Liberal, conservative, Canadian, American. Didn't matter to us then. We all knew it was going to lead to war, and when we were all pointed to Iraq and Afghanistan, we just accepted it and went for it. I still think it needed to be done, just not then and there. But to say the Taliban and Saddam didn't deserve to go down is also wrong.
Not true by a long shot. In 2003, a majority of Americans wanted the US to stay out of Iraq if the UN security council did not approve the invasion. A majority of Democrats in congress voted against the authorization of use of force. (and many who voted for it said they were against the invasion).
