That's why I insist that a popular native resistence movement is a necessary precondition for useful regime change. There was no such popular movement in Iraq and so I don't believe that even the Powell Doctrine would have resulted in the kind of government Bush keeps flogging. In fact, I don't believe it would have resulted in a stable government at all.
I never said the result would be this wonderful Democracy, just that one can "keep the peace" under those circumstances.
