I wrote that Saddam was the US's ally, I wrote that there wasn't a hue and cry for humanitarian intervention back then. By the way, you need to check out what Saddam was up to after the Gulf War. He kept on killing. It wasn't limited to the Iran/Iraq War. His numbers dwarfed Milosevic's after the war.
The point I was making is this: you had a genocidal lunatic in Iraq who was still killing (dissidents and Kurds, mainly). If retribution for past crimes applies to policy against the Serbs then how do you explain the attitude toward Hussein?
1,500 were killed over two years prior in battling between a terrorist group, the KLA, and Serbian police in the province. We are talking about a low-level counter-insurgency. This pales in comparison to what Saddam was doing well past the Iraq-Iran War. 30,000 are estimated to have been executed as political prisoners alone in the years leading up to the recent invasion/war.
