International Institute for Strategic Studies

IISS (United Kingdom)

The International Institute for Strategic Studies (IISS), founded in 1958, is an independent centre for research, information and debate on the problems of conflict, however caused, that have, or potentially have, an important military content. It aims to provide, through publications and discussion forums, the best possible analysis on strategic trends, and to facilitate contacts that would lead to the development of better public policy in the fields of international relations and international security. Based in London, the IISS has offices in the US, Germany, Singapore and Bahrain. The IISS Non-Proliferation and Nuclear Policy Program seeks to provide objective assessments of proliferation threats, to support international efforts to strengthen nuclear security and the non-proliferation regime and to encourage a stronger congruence of non-proliferation and arms control policies.
