Carl von Clausewitz

"Name the political object. Then spend the force it needs."

Carl von Clausewitz (1780–1831) was a Prussian general and the author of On War. A staff officer of the Napoleonic wars and later director of the War Academy, he argued that war is a continuation of policy by other means. Marie von Brühl published the unfinished manuscript in 1832.
