Nuclear Issues

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. 

Rebecca Davis Gibbons and Stephen Herzog provide an update on current efforts to eliminate nuclear weapons. 

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.

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 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.

Over the last two decades, there has been a dramatic increase in the popularity of financial sanctions as an instrument of US foreign policy to address security threats ranging from weapons of mass destruction (WMD) proliferation and terrorism to human rights violations and transnational crime. Washington’s policymakers have prized these tools for their ability to rapidly apply pressure against foreign targets with few perceived repercussions against American business interests. The problem, however, is that Washington is ignoring a growing tension between financial sanctions designed to support economic statecraft (with non-financial goals) and those designed to protect the international financial system. Confusing the two sends mixed signals to adversaries as well as allies and undermines US credibility and commitment to upholding international banking rules and norms. If Washington cannot reconcile these competing processes, it is unlikely that future administrations will enjoy the same foreign policy levers, leaving the United States at a significant disadvantage.
