Center Experts Reflect on 75th Anniversary of Hiroshima Bombing

On August 6, 1945, the United States dropped an atomic bomb on Hiroshima, Japan, launching the nuclear age. On the 75th anniversary of that somber event, Belfer Center experts reflect on the event and its aftermath.

'What About China?' and the Threat to US–Russian Nuclear Arms Control

| 2020

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

Will New START nuclear treaty survive ‘hostile’ US-Russia relations?

| June 23, 2020

The United States and Russia have about 91% of the world's nuclear warheads. And the arms control pact — the New START Treaty — between the two nations expires next year. Matthew Bunn spoke with The World's Marco Werman about the implications of the treaty.

The Postponement of the NPT Review Conference. Antagonisms, Conflicts and Nuclear Risks after the Pandemic

The Bulletin of Atomic Scientists has published a document from the Pugwash Conference on Science and World Affairs concerning nuclear problems and tensions in the time of COVID-19. The document has been co-signed by a large number of Pugwash colleagues and personalities.

Combating Nuclear Smuggling? Exploring Drivers and Challenges to Detecting Nuclear and Radiological Materials at Maritime Facilities

| June 03, 2019

International concern over nuclear terrorism has grown during the past few decades. This has driven a broad spectrum of efforts to strengthen nuclear security globally, including the widespread adoption of radiation-detection technology for border monitoring. Detection systems are now deployed at strategic locations for the purported purpose of detecting and deterring the smuggling of nuclear and radioactive materials. However, despite considerable investment in this area, few studies have examined how these programs are implemented or the operational challenges they face on a day-to-day basis. This article seeks to address this with a focus on radiation-detection efforts at maritime facilities. Utilizing practitioner interviews and a survey, this article identifies the factors that influence the planning and use of these systems in this fast-moving environment. The results clearly demonstrate that the implementation of these systems varies significantly across different national and organizational contexts, resulting in a fragmented global nuclear-detection architecture, which arguably undermines efforts to detect trafficked nuclear-threat materials. Greater consideration should therefore be given to developing international standards and guidance, designing and adopting tools to support key parts of the alarm assessment process, and broader sharing of good practice.

Revitalizing Nuclear Security in an Era of Uncertainty

| January 2019

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

How the Next Nuclear Arms Race Will Be Different from the Last One

| 2019

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

Trump’s INF Announcement: Another Gift to Putin?

| Oct. 25, 2018

Pulling out of the INF Treaty would be a strategic blunder. It would free Russia to deploy currently prohibited missiles without constraint and further undermine U.S. credibility with our allies. The United States would shoulder the blame for the collapse of one of the two remaining U.S.-Russian agreements controlling nuclear weapons. U.S. withdrawal would remove valuable verification mechanisms and introduce additional U.S. and Russian uncertainty regarding the other’s nuclear forces and intentions.
