In September 1999, St. Antony's College, Oxford, hosted a conference on how the intelligence services of the world should respond to the changes in world politics that have flowed from the collapse of the Soviet Union. No less important was their discussion of how the revolution in information technology is challenging the time-honored methods used by the intelligence community. This book reproduces the papers delivered and offers an edited account of the discussion. The conference involved senior intelligence officers from six different countries, among them a former Director of the CIA, the Deputy Chief of the British SIS, the head of the KGB's Illegals Directorate and their counterparts from Italy, Sweden, and France.
