The Senior Executives in National and International Security program at Harvard Kennedy School provides a two-week executive education program for senior national security leaders from the US and abroad. The program aims to deepen understanding of current security issues and allow participants to exercise decision-making skills through interaction with peers from military, government, and industry. Participants engage in formal classes, seminars, and discussions on topics like counterterrorism, security policy, and international relations. Past participants include leaders from the Joint Chiefs of Staff, State Department, and foreign militaries.
