Global security examines organized political violence in the global system. It encompasses traditional concerns about interstate and intrastate war, coercive diplomacy, collective security alliances, and weapons of mass destruction, as well as a host of nontraditional problems in cybersecurity, biosecurity, climate security, human security, and terrorism. A diverse set of course offerings explores topics such as the geopolitics of cyberspace, grand strategy, intelligence, and covert action, terrorism research, police violence, far-right populism, and Canadian defense policy. In order to devise humane and effective policies to mitigate conflict in the global system, it is imperative to understand its root causes. The program thus encourages students to understand the causes, conduct, and consequences of transnational violent conflict, whether merely threatened or realized, occurring between or within states, involving military or nonmilitary organizations, and transpiring throughout the gray zone between peace and war.
