The role of intelligence in U.S. government operations has changed dramatically and is now more critical than ever to domestic security and foreign policy. This authoritative and highly researched book provides a detailed overview of America's vast intelligence empire--its organizations, its operations (from spies on the ground to satellites thousands of miles in space), and its management structure. Relying on a multitude of sources, including hundreds of official documents, author Jeffrey T. Richelson provides an up-to-date picture of the U.S. intelligence community that will allow students to understand the full scope of organizations and activities and give valuable support to policymakers and military operations. Fully revised throughout, the sixth edition of this definitive book includes new material on intelligence organization, foreign and domestic intelligence collection and analysis, covert action, and cooperation with foreign intelligence services.
