The United States intelligence establishment is a colossus. With stations in 170 countries, armed with cutting-edge surveillance gear, high-tech weapons, and fleets of armed and unarmed drone aircraft, it commands the most extensive and advanced intel force in history. But America's spy establishment still struggles to keep pace with a host of determined enemies around the world.

In Intel Wars, leading espionage historian Matthew M. Aid delivers the inside stories of our decade-long struggle against terrorism - its hard-won successes and bedeviling failures.

Based on extensive, on-the-ground interviews on the front lines and in D.C., as well as revelations from Wikileaks cables and other newly declassified documents, Intel Wars is the most authoritative account yet written of the secret war that America is still fighting.
