Nuclear Issues

Nickolas Roth reflects upon Doomed to Cooperate by Siegfried S. Hecker, which tells the story of how, after the Cold War ended, U.S. and Russian scientists worked together to strengthen Russian nuclear safety and security, reduce proliferation risks, and advance nuclear science. He identifies that the book provides important lessons for policymakers in each country who are, just as they were more than two decades ago, scrambling to cope with the rapidly changing relationship between the world’s two largest nuclear superpowers.

The collapse of the Soviet Union in 1991 created unprecedented dangers. The crumbling empire had thousands of nuclear weapons, enough material to make tens of thousands more, and tens of thousands of experts with sensitive nuclear expertise. To overstate only slightly, Doomed to Cooperate: How American and Russian Scientists Joined Forces to Avert Some of the Greatest Post–Cold War Nuclear Dangers is a true story of scientists and engineers successfully working together to save the world.

This week the National Nuclear Security Administration (NNSA) announced that 546 kilograms of plutonium and highly enriched uranium (HEU) shipped from Japan arrived in the United States.

The 2016 nuclear security summit was a pivotal moment for the decades-long effort to secure nuclear material around the globe. More than 50 national leaders gathered in Washington for the last of four biennial meetings that have led to significant progress in strengthening measures to reduce the risk of nuclear theft.

In this journal article for Survival, Aaron Arnold argues that the success of financial sanctions rests largely on the dominance of the US dollar and the correspondent banking system. Yet emerging trends could undermine Washington’s capacity to employ this tool.

Extended deterrence has been a main pillar of the security alliance between the United States and South Korea (Republic of Korea [ROK]) since the end of the Korean War. The changing dynamics of US extended deterrence in Korea, however, affected Seoul’s strategic choices within its bilateral alliance relationship with Washington. Examining the evolution of US extended deterrence in the Korean Peninsula until the Nixon administration, this article explains why South Korea began its nuclear weapons programme in a historical context of the US–ROK alliance relationship. This article argues that President Park Chung-hee’s increasing uncertainty about the US security commitment to South Korea in the 1960s led to his decision to develop nuclear weapons in the early 1970s despite the fact that US tactical nuclear weapons were still stationed in South Korea.

The just-concluded fourth and final nuclear security summit saw some serious progress, but also some missed opportunities.
