The Art of War even though written in China more than 2,000 years ago is still a valuable resource for military education. Sunzi is an honorific title bestowed on Sun Tzu. Besides writing The Art of War Sunzi is also the first realist in international relations theory. The Art of War is the first known attempt to formulate a rational basis for the planning and conduct of military operations. Master Sun's two-thousand-year-old advice on war strategy appears twice: first by itself and then interspersed with commentary, mostly by Chinese scholars, attesting to the text's philosophical relevance to modern culture. The principles of war outlined in this volume are still used by Chinese generals. The Art of War is one of the most influential books in China and has been studied by military personal all over the world.
