Institute for Science and International Security

The Institute for Science and International Security is a small Washington, D.C. nonprofit led by founder David Albright, a former IAEA nuclear inspector. Its work centers on technical assessments of nuclear weapons programs, particularly Iran and North Korea, and it is widely cited by policymakers and journalists. Its analyses tend to emphasize threat timelines and weapons-development risks, which has historically aligned with hawkish policy positions on Iran even as the Institute declines a partisan label.
