The Oxford Handbook of War is the definitive analysis of war in the twenty-first century. With over forty senior authors from academia, government and the armed forces world-wide the Handbook explores the history, theory, ethics and practice of war. The Handbook first considers thefundamental causes of war, before reflecting on the moral and legal aspects of war. Theories on the practice of war lead into an analysis of the strategic conduct of war and non Western ways of war. The heart of the Handbook is a compelling analysis of the military conduct of war which is juxtaposed with consideration of technology, economy, industry, and war. In conclusion the volume looks to the future of this apparently perennial feature of human interaction.
