1. Iraq (Saddam and post-Saddam) is not a signatory to the International Criminal Court Treaty;
2. Neither is the U.S., giving the new Iraqi government as Saddam's successor and the U.S. as the occupying power the right to determine how and whether to try officials of the old regime. The post-WWII trials were NOT under the auspices of the UN; they were under the auspices of the U.S., Britain, France and the Soviet Union;
3. It is the Iraqis who, while not the only ones to suffer as a result of Saddam, were certainly the primary victims. Therefore, it only stands to reason that a post-Saddam government should try Saddam for the slaughter of his own countrymen, anong other things;
4. Have you followed the Milosevich prosecution? that farce is so tied up in knots that it's very possible that old Slobo will skate away a free man - and what a tragic injustice that would be.
5. Any prosecution by an entity perceived in the Islamic world as "Western" - and the ICC is certainly so viewed - would result in a fresh wave of terror, this time directed at Europe and the UN as well as the U.S. We already have the deadenders attacking UN facilities in Baghdad, after all. Best that the practicioners of Islam try a fellow Muslim - however apostate to his faith he may be.
No, Charlie, best to leave the prosecution of Saddam to Iraqis with the American role strictly limited to gathering evidence and providing security.
