It's no accident that politicians like Hillary Clinton are seeking to internationalize the upcoming trial of Saddam. A brief look at their worldview helps to understand why this is so important to them.
Those who take a traditional worldview view the concepts of Right and Wrong as objective concepts that transcend human existence. Generally, Right and Wrong are based on the 10 Commandments and "The Golden Rule". But for liberals and "progressives" it's a different story.
For them, Right and Wrong are based more on majority opinion rather than on absolute concepts. Right and wrong are malleable and can be molded depending on the situation. On further clarification, when I say "majority" opinion" I'm not referring to a simple majority of all people but to a majority of the elites. For progressives, someone is elite if they attended the proper ivy league school, if they are from the East Coast, and more importantly, if they are willing to ascribe to the set of values that the other elites espouse.
The "international community" to the liberals, represents the opinion of the majority of elitists around the world and therefore, must be right. Concepts like national sovreignty are anathema to them. That is why liberal media outlets like the Washington Post, insist on internationalizing Saddam's trial.
Yet it is a sense of national pride (and sovreignty) that is so needed by Iraqi's at this point. Just as liberals don't seem to understand that diversity means having a sense of pride in your own heritage (whatever that may be) and instead seek to reduce everyone's heritage to a rough equivalency, so they are seeking to do the same with nationalism.
The Iraqi people were the ones who suffered the greatest under Saddam and they should be the ones to try and, hopefully, execute him. It is necessary for all of Iraq to acknowledge the injustice that was done in order for the country to move beyond this painful event. It is also necessary for the Iraqi people to realize that the future (just as Saddam's future) is in their hands.
George Will has an excellent commentary on why the trial of Saddam should be in Iraq.
