Regardless of what you think of Kanan Makiya or his history as an apologist for American foreign policy, In this article in The Observer he says now that the administration plan for a US military government in Iraq is a betrayal.
"Every word that I have committed to paper in the last quarter of a century is, in one way or another, an application of the universal values that I have absorbed from many years of living and working in the West to the very particular conditions of Iraq.The government of the United States is about to betray, as it has done so many times in the past, those core human values of self-determination and individual liberty."
How he could imagine they would have any other plan, or that any other plan even would be feasible following an invasion, I don't know.
