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.

David W. Kearn argues that deployment of nuclear weapons cannot rectify a perceived imbalance in conventional forces in the western Pacific.

For months, evidence has accumulated that North Korea may be preparing its seventh nuclear explosive test. Continuous warnings by analysts and the media about this possibility are a sobering reminder that Pyongyang's continued pursuit of a larger nuclear arsenal remains a challenge for the Non-Proliferation Treaty and the nonproliferation regime. This continues to be the case even as the public and leaders around the world have largely shifted their attention to the nuclear dimensions of the war in Ukraine.

The world has grown more dangerous but also less open to arms control measures that could limit some of the dangers. What can be done? Steven E. Miller offers a tour de force overview of both dismal and hopeful trends within arms control over the past decades, in this first paper of a new HCSS series on Arms Control.

In the authors' view, neither formal NATO membership nor nuclear weapons are fitting security options for Ukraine in the face of Russian aggression. To secure its borders and achieve sustainable peace and stability in Europe, Ukraine should forge a treaty-based strategic alliance directly with the United States.

William d'Ambruoso explains why high-level engagement, built on a baseline of deterrence, lessens the chances of war and opens the way for future cooperation in North Korean–U.S. relations.

Rebecca Davis Gibbons and Stephen Herzog provide an update on current efforts to eliminate nuclear weapons. 

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 authors conducted a study which highlights how the U.S. public as a whole and various demographic groups view President Donald Trump's positions on nuclear weapons.

Civil society has played a very important role in nuclear security over the years, and its role could be strengthened in the future. Some nuclear organizations react against the very idea of civil society involvement, thinking of only one societal role—protesting. In fact, however, civil society has played quite a number of critical roles in nuclear security over the years, including highlighting the dangers of nuclear terrorism; providing research and ideas; nudging governments to act; tracking progress and holding governments and operators accountable; educating the public and other stakeholders; promoting dialogue and partnerships; helping with nuclear security implementation; funding initial steps; and more. Funding organizations (both government and non-government) should consider ways to support civil society work and expertise focused on nuclear security in additional countries. Rather than simply protesting and opposing, civil society organizations can help build more effective nuclear security practices around the world.
