They include officials and scientists from a wide range of agencies and institutions. Among them are officials or former officials from Israel, Egypt, Pakistan, Canada, Korea, and Japan, from the U.S. departments of state, energy, and defense, the U.S. Senate, the National Security Council, the U.S. Arms Control and Disarmament Agency, the International Atomic Energy Agency, the United Nations, the Nuclear Threat Initiative, MIT, Los Alamos National Laboratory, the College of William and Mary, and the University of California.
