With nuclear proliferation essentially eliminating full-scale warfare, governments have increasingly turned to what Richard W. Cottam calls competitive interference. This type of policy invokes counter-insurgency, political, economic, and psychological manipulations, and often involves looking deeply into the internal affairs of a country, often secretly. Cottam describes and defines competitive interference, explores the United States' institutional adjustment to it, and provides a theoretical framework for projection and evaluation of foreign policy in this changing diplomatic arena. He uses case studies of international relationships involving the United States, India, China, Vietnam, Iran, and the former USSR and East Germany to evaluate his theoretical stance, and proposes long-term institutionalization of policy, rather than covert operations.
