Iraq had ZERO to do with 9/11. Iraq did NOT have any weapons of mass destruction. I am all for taking it to the enemy, but the war in Iraq did not do that. I prefer wars of choice over letting another pearl harbor or 9/11 happen as well as you do...taht doesn't mean that I would, therefore, blythely endorse a war of choice against Sri Lanka, for example, just for the hell of it....
Saddam was an asshole, no doubt...but he did three things better than we did:
1. kept islamic extremists out of his country
2. kept sunnis and shiites from killing one another
3. kept Iran's regional hegemony in check
Our war on terror would be much better served if we had SOMEONE doing those three things better than we have been doing those three things.
