Institute for Science and International Security

The Institute for Science and International Security is a non-profit, non-partisan institution dedicated to informing the public about science and policy issues affecting international security. Its primary focus is on stopping the spread of nuclear weapons and related technology to additional nations and to terrorists, bringing about greater transparency of nuclear activities worldwide, strengthening the international non-proliferation regime, and achieving deep cuts in nuclear arsenals. The Institute is widely recognized both as a source of authoritative information on nuclear programs in states that seek or possess nuclear weapons and an important contributor to efforts to stop the spread of nuclear weapons. The Institute’s projects integrate technical, scientific, and policy research in order to build a sound foundation for a wide variety of efforts to reduce the threat posed by nuclear weapons to U.S. and international security.
