CAMBRIDGE, MA — The world has entered a new nuclear era. No longer dominated by only two nuclear superpowers, the evolving multipolar nuclear order presents fundamental challenges to the conceptual and practical means of avoiding nuclear war. Moreover, the new era has slowly dismantled the bilateral arms control framework, with no clear prospect that it will be revived and extended. The possibility that a framework or frameworks encompassing other, let alone all, nuclear powers can be achieved seems even more remote. In addition, advances in weapons technology and the opening of new frontiers, such as cyber capabilities and artificial intelligence, make a shifting environment still more complex. The pathways to inadvertent nuclear war have multiplied across more regions and relationships.
The Spring 2020 issue of æ岹ܲ, “Meeting the Challenges of a New Nuclear Age,” guest edited by Robert Legvold (Ƶ Member; Columbia University) and Christopher F. Chyba (Princeton University), is one of several research publications to come out of the Ƶ’s project on “Meeting the Challenges of the New Nuclear Age.” The project as well as the issue examine some of the possible escalation pathways that could lead to the use of nuclear weapons.
A collection of fourteen essays authored by a diverse group of security scholars, physicists, statesmen, and political scientists, this issue of æ岹ܲ offers analyses that are sensitive to the challenges posed by a world with nine nuclear players, with a primary emphasis on the United States, Russia, and China. The focus is on salient aspects of the changes underway among the major nuclear powers. The intent is to capture the essential features of the nuclear world we have entered, to stimulate among policy-makers and the engaged public a recognition of the challenges that it poses, and to identify mitigating steps to reduce nuclear dangers.
