COUNTERINTELLIGENCE
COUNTERINTELLIGENCE
The publication of Christopher Andrew's Defence of the Realm, the authorized history of Britain's Security Service (or MI-5 as it continues to be known familiarly) is an extraordinary event, not least because it points to the differences between how the United States and Britain address counterintelligence and domestic security. Within the US/UK "special relationship," intelligence and security have been for nearly 75 years the most intimate part of an extraordinary partnership. Yet Professor Andrew's massive work (nearly 900 pages of text with another 150 pages of notes) highlights in a dramatic way that in Britain counterintelligence and domestic intelligence are core responsibilities, with the Security Service and its missions afforded parity with what the U.S. called, until 9/11, "foreign intelligence." It has been decades since American counterintelligence enjoyed similar prominence.
