Seminar XXI is an educational program for senior military officers, government and NGO officials, and executives in the national security policy community. The program’s objective is to provide future leaders of that community with enhanced analytic skills for understanding foreign countries and the relations among them.  Seminar XXI began in 1986 as an experimental program adapted from several graduate-level courses taught at MIT. Over the years it has provided an opportunity for frank and challenging exchanges of ideas between policymakers and university scholars, as well as among the Fellows, who themselves represent a wide range of institutions and organizations in the policy-making community. We are now in our twenty-fifth year and have more than 1,600 alumni/ae.
