This course examines in-depth the Soviet seventy-year intelligence and counterintelligence operation on the West with emphasis on the Cold War. As many contemporary intelligence and counterintelligence services have been heavily influenced by the KGB and its successor organizations, knowledge of the KGB's past and its operational philosophy lay the groundwork for the study and evaluation of the operations of numerous secret services, as well as enable the student to gain a strong appreciation for the role of an intelligence service in a "counterintelligence state." This is a critical ingredient for understanding the Cold War and its legacy.
