In an increasingly interdependent world, states complement their national security policies increasingly through security cooperation. The course inquires into the concepts of cooperative security, such as alliances, collective security, arms control and confidence-building nonproliferation, as well as into the real-world institutions created for implementing concepts such as NATO, the United Nations, the International Atomic Energy Agency and the various instruments created to combat international terrorism. Finally, explores the way in which theories of international relations discuss security cooperation. The course alternates between lectures and students’ presentations. (T&H)
