Divided into five sections, the introduction surveys American involvement in the First World War and provides a guide to the collection itself. The first section, “War Guilt, Disillusionment, and Beyond,” charts broadly the way the war was seen during wartime and in the postwar era up to the present. Section two, “Why the First World War Was Fought and the United States Joined,” examines briefly why the war occurred and why the United States, distant from the center of the conflict, became involved. One important aspect contributing to that involvement—the debate among American intellectuals that came largely to embrace the Allies--is the subject of section three, “The Great War and the Intellectuals.” Section four, “How the United States Built an Army, Won the War, and Lost the Peace,” considers how the US fought the war, its role in the outcome, and the ultimate defeat of Wilson’s vision of a US-led postwar world order. The final section, “How to Read This Book,” highlights its three overall aims: canvassing the diverse forms of war literature and culture; analyzing the many settings and perspectives that occasioned responses to the war, and describing the depth and durability of the war’s impact.
