Securing Nuclear Weapons and Materials Worldwide: Expanded Funding Needed for a More Ambitious Approach

| Apr. 19, 2019

The Trump administration budget request for programs to reduce the dangers of nuclear theft and terrorism is too small to implement the ambitious approach that is needed. Congress should increase funding in this critical area; direct the administration to develop and implement a comprehensive plan for improving security for nuclear weapons and materials worldwide; and exert expanded oversight of this effort. This brief highlights the importance of ongoing nuclear security work; describes the evolving budget picture; and outlines recommendations for congressional action.

Combating Complacency about Nuclear Terrorism

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.

A Vision for Nuclear Security

| January 2019

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.

The risks of nuclear escalation between the U.S. and China or Russia are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems. What can be done to reduce this risk?

Nuclear Battleground: Debating the US 2018 Nuclear Posture Review

| June 2018

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.

Evaluating the Nuclear Posture Review

In February, the Pentagon released a new Nuclear Posture Review (NPR), a comprehensive overview of the nation’s nuclear forces, their disposition, and plans for the future. Here, Belfer Center experts share their assessments of this NPR and the future of America’s nuclear capabilities.

Verifying the Elimination of Nuclear Weapons and Providing Assurance against Breakout

| February 2018

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.
