International Security

Complacency about the threat of nuclear terrorism—the belief that nuclear and radiological terrorism threats are minimal and existing security measures are sufficient to address them—is the fundamental barrier to strengthening nuclear security. Many factors can lead to complacency, but the most significant contributors are lack of knowledge about: events related to nuclear terrorism; weaknesses of nuclear security systems; and the capabilities demonstrated by thieves around the world. People will be more likely to take action to strengthen nuclear security if they believe that nuclear terrorism poses a real threat to their own country’s interests and their actions can significantly reduce the threat. There have been many incidents in recent years that demonstrate the need for strong and sustainable security at both military and civilian nuclear facilities.

The author analyzes the policy implications of the U.S. January 2019 Missile Defense Review.

The goal of global nuclear security efforts should be a world in which all countries with nuclear weapons, highly enriched uranium (HEU), separated plutonium, and nuclear facilities whose sabotage could cause a major radiation release have reduced the risk of nuclear theft and sabotage to the lowest possible level. This will require policymakers, regulators, and operators to commit to a continuous process of striving for excellence in nuclear security performance.

This Policy Brief compares and contrasts the Trump administration’s 2018 Nuclear Posture Review with past reviews and its Obama predecessor. It concludes that this review offers a much harsher assessment of the security environment; it posits a more expansive role for nuclear weapons; and proposes a substantial de-emphasis on arms control.

Effective verification will be absolutely essential to achieving nuclear disarmament. Developing effective verification may seem an impossible challenge, but there is substantial experience to build on, including IAEA safeguards and bilateral arms control processes. Examining the specific steps required to progress disarmament, we are not starting with a blank sheet, many verification missions are similar to those existing or under development today. International collaboration in developing new verification applications will contribute to the confidence and trust required to achieve the elimination of nuclear weapons.

Chairman Rogers, Chairman Poe, Ranking Member Cooper, Ranking Member Keating, distinguished members, I appreciate and am honored by the opportunity to testify before your joint subcommittees on such an important topic. As a former official of the Obama Administration, I wanted to note for the record that I am testifying today in my personal capacity, and not speaking for any organization or governmental agency or institution.
