Keegan was also criticised by peers, including Sir Michael Howard and Christopher Bassford for his critical position on Carl von Clausewitz, a Prussian officer and author of "Vom Kriege" ("On War"), one of the basic texts on warfare and military strategy. Keegan was described as "profoundly mistaken". Bassford stated, "Nothing anywhere in Keegan's work – despite his many diatribes about Clausewitz and 'the Clausewitzians' – reflects any reading whatsoever of Clausewitz's own writings." The political scientist Richard Betts criticised Keegan's understanding of the political dimensions of war, calling Keegan "a naïf about politics."
