In March 2003, the Institute of War and Peace Studies (IWPS) was renamed the Arnold A. Saltzman Institute of War and Peace Studies (SIWPS) in honor of Ambassador Arnold A. Saltzman. Today, the Institute is directed by Richard K. Betts. Says Betts, "War and peace are two sides of a coin; neither is fully understandable apart from its alternative. The Saltzman Institute is committed to building and integrating the stock of knowledge on both sides of the coin."
From the beginning, the Institute has interpreted its role broadly. Over the years, researchers have probed the political, military, historical, legal, economic, moral, psychological, and philosophical dimensions of international relations. Although the Institute does not take an official position on any public policy issues, its members contribute to this discourse by authoring books and articles, discussing current issues with officials and journalists, serving as consultants to government departments and agencies, and testifying before Congressional committees.
The Institute itself has no formal teaching program; rather, its members conduct a wide variety of instructional activities through the Department of Political Science and the School of International and Public Affairs (SIPA) at Columbia University. Members of the Institute offer courses on American foreign policy, national security, international politics, political economy, environmental policy, and international organizations.
