Islam is not a religion of peace, and it is clear that Saddam must go simply because we cannot allow every nickel and dime dictator to have the means to destroy American cities.
Nonetheless, the United States has been an inconsistent force for peace and democracy in the Middle East. We should have pushed the Saudi regime toward democracy a long time ago. We should have gone into Baghdad in '91, rather than listen to the United Numbskulls and imposed blockades and sanctions which have only ended up harming Iraqi children. And we should have pressed the Israelis into forming a Palestinian State (though with safeguards to assure that Yassir Arafat is not in charge of it, and that it does not become a launching pad for terror attacks against Israel).
In short, we should either have stayed out the region entirely, or we should have done some good. This business of half measures has failed us. Today we are rectifying the problem.
