Interesting read but I sense some deep hatred toward clausewitz. I wonder why.

Some points:
-He largely ignores Clausewitz's "war is continuation of policy with different means" dictum. Which can be translated into "if you don't have clearly defined long term political goals military actions don't matter". and I think this is main problem in Iraq as golas of "making Iraq democratic" and such are not defined what exactly that means and can mean anything or nothing.
-The article gives the impression that US military is like medrassah where only Clausewitz is taught. while I don't have any first hand experience with such institutions I seriusly doubt this is the case.
-author argues for abandoning Clausewitz. I disagree. He is still relevant though it's necessary to define works that are relevant as well. If you identify guerilla/insurgency/LIC as "next thing" then Mao, Che, Lawrence etc are relevant but Clausewitz should not be ignored. Specially military-policy relations which are extremly important in such conflicts
