Hew Strachan and Andreas Herberg-Rothe have produced an important - no, an essential - volume of articles that illuminate and explore the core ideas of Carl von Clausewitz. The results of an Oxford Conference on Clausewitz in 2006, the articles both engage current thinking on Clausewitzian theory and open up new areas of relevance of that theory and philosophy. This book is the single most important collection of essays on the subject since Michael Handel produced his volume of essays in 1986. The subject matter discussed ranges from the well-traveled (Clausewitzian ideas of war and politics) to the mostly ignored (the ideas of Defense, the long-overlooked Book VI of "On War.") The book is for serious students and researchers on war, not the bloggers and b.s. artists who cut and paste others' ideas and express them out of context.
