The Programme for Strategic and International Security Studies is an integral part of the Graduate Institute of International Studies. its task is to promote more and better understanding of the main trends, issues and possible solutions to problems in this world of uncertainty - to identify issues of particular concern to Europe and to Switzerland - and to maintain a dialogue with all the institutions and leaders, private and public, who share the concern for a more orderly, predictable and, hence, more peaceful world. PSIS organises a series of seminars and has an extensive documentation service relating to questions of international security and disarmament and their economic impact.
