The classic book that established the principles and methods of modern intelligence analysisWith the outbreak of the Second World War, historian Sherman Kent left his classroom at Yale to join the Office of Strategic Services—the forerunner of the Central Intelligence Agency—where he adapted scholarly methods to the rigors and unique challenges of producing actionable intelligence in support of the war effort. In this remarkable book, Kent draws on the lessons he learned in wartime to lay the foundations for postwar security. He presents the doctrine and practices of intelligence analysis and explains why they are vital to national survival. Strategic Intelligence for American World Policy shows how intelligence activities and their consequences extend far beyond military considerations and are as essential to keeping the peace as they are to winning the war.
