The role of intelligence in US 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 US intelligence community that will allow students to understand the full scope of organizations and activities and will give valuable support to policymakers and military operations. Hailed by the Washington Post Book World as "the authoritative survey of the American cloak-and-dagger establishment," this important text is now fully revised and updated. The fifth edition includes new material on homeland security intelligence, POW and detainee interrogation, and national intelligence organizations.
