Criticism Clausewitz and his proponents have been severely criticized by other military theorists, like Antoine-Henri Jomini in the 19th century, B. H. Liddell Hart in the mid-20th century, and Martin van Creveld and John Keegan more recently. On War is a work rooted solely in the world of the nation state, states historian Martin van Creveld, who alleges that Clausewitz takes the state "almost for granted", as he rarely looks at anything before the 1648 Peace of Westphalia, and mediaeval warfare is effectively ignored in Clausewitz's theory. He alleges that Clausewitz does not address any form of intra/supra-state conflict, such as rebellion and revolution, because he could not theoretically account for warfare before the existence of the state.
