Surveys how American strategic theorists have understood the nature and character of war in the twentieth century.

Antulio J. Echevarria II reveals how successive generations of American strategic theorists have thought about war. Analyzing the work of Alfred Thayer Mahan, Billy Mitchell, Bernard Brodie, Robert Osgood, Thomas Schelling, Herman Kahn, Henry Eccles, Joseph Wiley, Harry Summers, John Boyd, William Lind, and John Warden, he uncovers the logic that underpinned each theorist's critical concepts, core principles, and basic assumptions about the nature and character of war. In so doing, he identifies four paradigms of war's nature - traditional, modern, political, and materialist - that have shaped American strategic thought. If war's logic is political, as Carl von Clausewitz said, then so too is thinking about war.
