The way Saddam ruled was the only way Iraq could be ruled as it currently is. His only mode of authority could be only oppression, because of the inherent problems in dealing with people of different religious convictions in that kind of numbers, and the insurgents and such. Right now, Iraq has just been turned into a big training ground against the US for insurgents, who are mostly not native Iraqis. So, therefore, Iraq itself must be changed. I don't know how, I don't think that right now anybody knows how, and people SHOULD HAVE KNOWN BEFORE THEY INVADED.
