A government such as Mr Bush's would have been voted out in Canada sometime well prior to 2004, probably prior to 2003. The Iraq War would never have been allowed to happen at all, because there was no legal or rational basis for waging it.

Well, our system here is not that different from yours in some of those ways, Little Hawk, and it didn't work out that way. No legal or rational for the war didn't stop our MPs believing what they were told (or making out that they believed it), and lining up to vote for the war.
