No. But that's not the point.
One doesn't predicate the success of a program on its most optimistic possible outcome, but on its most pessimistic.
What do you think will happen if Iraq's future (still unformed) government fragments on ethnic and/or religious lines? Remember Lebanon?
Iraqis haven't had democratic self-rule in a generation. Corruption? You bet. The question is not "will there be any?", but "how well will the government be prepared to counteract it?"
I don't think the new government of Iraq could be less responsible that Saddam's regime, but not to consider the possibility that it could be as responsible, in its own unique way, is irresponsible on our part. So we plan for the worst and hope those plans stay in the drawer.
