"Part I of this book explores the vital relationship between strategy and politics--and the general failure to observe it-- in the last four wars the United States has fought, from World War I to Vietnam. Part II is devoted to a philosophic though always readable consideration of such subjects changing social attitudes towards war; the inadequacy of popular theories purporting to explain the causes of war; the ambiguity of the 'vital interest' for which nations are so ready to fight; the nature of the people who plan war and fight it, and much more."
