It is quite true that a significant part of the intel used to go to war was false testimony from someone we torture. And the violation you mention was with the UN, and not the US. So, you can't use it as justification. The point is, we took that false testimony and made a show of it as rationale to go to war.That's not true at all, we didn't go to war because of some possibly wrong info. There were many reasons to go into Iraq. Violation of the cease fire, for one. Iraq fired on our planes enforcing the no fly zone. You can stop right there.
