Nuclear Issues

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

In this Q&A, Joseph S. Nye talks about his advice for the interim and future president of Harvard in the wake of Claudine Gay's resignation, which countries should be highest on our radar to prevent the threat of nuclear war, what role the U.S. should play in the Russia-Ukraine war, the significance of U.S. alliances in the Middle East, and more.

At a moment when arms control is deeply troubled and may be dying, two eminent scholars, Marc Trachtenberg and the late Robert Jervis, have taken a fresh look at the beginnings of strategic arms control fifty years after the signing in Moscow of the SALT I agreements in May of 1972. They do so from different vantage points, writes Steven E. Miller.

As diplomats, activists, and researchers converged on Vienna in June for the first meeting of states-parties to the Treaty on the Prohibition of Nuclear Weapons (TPNW), recent tragic world events highlighted how critical it was to convene this multilateral forum on nuclear disarmament.

Since February, Russia’s war against Ukraine has epitomized the grave dangers of a world where nine states possess approximately 12,700 nuclear weapons.¹ That Russia could invade a sovereign state and indiscriminately target its civilian population, while using nuclear threats to deter NATO from intervening, has stunned the world. It offers a stark reminder that possessing nuclear arms can enable abhorrent violations of international law

Joseph Nye writes that even at this early stage, there are at least eight lessons— some old, some new— that the world is learning (or relearning) from the war in Ukraine.

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.

Mariana Budjeryn, research associate at Managing the Atom, speaks about the legacy of the 1994 Budapest Memorandum and the remnants of Soviet nuclear weapons in Ukraine.

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?
