Athene - re "Saddam was a horrible man".
Yes, he was. And there are quite a few other horrible men in the world, whose populations are being massacred today (rather than the Halabja etc of 1980s). What was so special about Iraq? Could it be that it is sitting on one of the largest oil reserves in the world?
You might have conveniently chosen to ignore this, but when US was about to invade Iraq, the reasoning was that Iraq was an "imminent threat", with huge arsenal of chemical weapons, looking to be a nuclear power. Nobody was saying "He is a horrible man" as justification for invasion.
In any case, "We think the leader is horrible" cannot justify invading a country and killing 90,000 of its civilians. There are international laws forbidding exactly this kind of flippant use of military force on other sovereign states.
And I still don't understand what the terrible alternative to invasion was. What do you think would happen if Saddam lived out the rest of his life isolated in his little corner of the Middle East? Killed a couple of hundred more dissenters. What else?
