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.

The risks of nuclear escalation are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems. 

"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.

In the United States and Europe, many believe that the best way to prevent Russia’s resumption of its historic imperial mission is to assure the independence of Ukraine. They insist that the West must do whatever is required to stop the Kremlin from establishing direct or indirect control over that country. Otherwise, they foresee Russia reassembling the former Soviet empire and threatening all of Europe. Conversely, in Russia, many claim that while Russia is willing to recognize Ukraine’s sovereignty and territorial integrity (with the exception of Crimea), Moscow will demand no less than any other great power would on its border. Security on its western frontier requires a special relationship with Ukraine and a degree of deference expected in major powers’ spheres of influence. More specifically, Russia’s establishment sentiment holds that the country can never be secure if Ukraine joins NATO or becomes a part of a hostile Euro-Atlantic community. From their perspective, this makes Ukraine’s nonadversarial status a nonnegotiable demand for any Russia powerful enough to defend its national-security interests.

When do states acquire nuclear weapons? History shows that only two types of states decide that the bomb is essential to their security: 1) very powerful states; and 2) weak states that lack ironclad security guarantees.

Policymakers have long focused on preventing nuclear weapons proliferation by controlling technology. Even developing countries, however, may now possess the technical ability to create nuclear weapons. The history of gas centrifuge development in twenty countries supports this perspective. To reduce the demand for nuclear weapons, policymakers will have look toward the cultural, normative, and political organization of the world.

"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."
