Karl von Clausewitz wrote in his classic book, "On War", that "war is a mere continuation of policy with other means.” Clausewitz viewed war as a political instrument. His book about military philosophy remains the most influential work on the history and strategy of war. An earlier authority on war was Sun Tzu. In his book "The Art of War", Sun Tzu saw war as a necessary evil. It was something people do.
