Nuclear Issues

As the best documented major crisis in history, in substantial part because Kennedy secretly taped the deliberations in which he and his closest advisers were weighing choices they knew could lead to a catastrophic war, the Cuban missile crisis has become the canonical case study in nuclear statecraft. Over the decades since, key lessons from the crisis have been adapted and applied by the successors of Kennedy and Khrushchev to inform fateful choices.

On March 31,  the Project on Europe and the Transatlantic Relationship and the Minda de Gunzburg Center for European Studies hosted a discussion with Wolfgang Ischinger, former Chairman of the Munich Security Conference, Joseph S. Nye Jr., Harvard University Distinguished Service Professor, and Daniela Schwarzer, Executive Director for Europe and Eurasia at the Open Society Foundations, on how Russia’s invasion of Ukraine as well as the brutality of its action has caused an unexpected reversal of Germany’s long time security policy and led to strong reactions in the rest of Europe, NATO, and the posture of the Biden administration. The seminar examined the dimensions and consequences of these developments for the future of the EU and the West. Karl Kaiser, Senior Fellow at the Project on Europe, moderated.

In light of Russia’s annexation of Crimea and its current threat to Ukrainian sovereignty, it’s fair to ask: What is the significance now of the Budapest Memorandum?

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

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.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

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.

Julius Weitzdörfer’s earliest childhood memories are the major global events of 1986—the Space Shuttle Challenger explosion and the Chernobyl disaster. Looking back, he realizes that these events must have contributed to shaping his later research interests in managing technological risks.
