Nuclear Issues

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.

During the latter part of the Cold War, many strategists thought of nuclear deterrence and arms control as two of the most essential stabilizing elements of the same strategy in managing an adversarial relationship. The renewed crisis between the West (the United States and NATO member states) and Russia demonstrates how critical these elements are to the strategic nuclear relationship. As a result of recent setbacks between Washington and Moscow in the past few years, arms control has taken a back seat, and the risk of conflict due to miscalculation is the highest it has been since the 1980s.

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.

"Ukraine's denuclearization had been a controversial issue even as it was negotiated, leaving bitter traces in the country's political and public discourse. As a student of political science in Kyiv in the mid-1990s, I remember being outraged by the sense of injustice: how could the states that rely on their own nuclear deterrents demand the nuclear disarmament of others? More so that one of these states, Russia, has never fully come to terms with Ukraine's independence. Since then, I came to research a doctoral dissertation on the denuclearization of post-Soviet successor states and, in the process, learned a great deal about Ukraine's nuclear disarmament that dispelled many of my preconceptions."

This spring, the United States hosted the fourth and final Nuclear Security Summit in Washington, DC. Senior representatives of more than 50 nations convened to mark the end of an unprecedented international initiative over the last six years to strengthen security measures aimed at preventing nuclear terrorism. During that time, many states made significant progress, but more work is needed.

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.

"Although the cancellation of the planned deployment of the SM-3 IIB interceptors has removed the possibility that interceptors deployed under the phased adaptive approach would pose a threat to Russian missiles, it has not diminished the missile defense system's primary mission of intercepting an array of current and potential future Iranian missiles. The restructured missile defense system would still theoretically be able to handle these Iranian missile threats, even if one factors in a comfortable amount of time for detecting and tracking them."
