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.

Belfer Center experts on the U.S.-China relationship and Middle East issues shared thoughts on the significance of the unexpected Iran-Saudi Arabia agreement brokered by China. 

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.

In this episode of "Intelligence Matters," host Michael Morell speaks with former senior CIA operations officer and Moscow station chief Rolf Mowatt-Larssen about the likely trajectory of the war in Ukraine, including the possibility of a negotiated peace — or dangerous escalation. Mowatt-Larssen offers insights on Putin's options, potential rifts among his intelligence agencies, and persistent rumors about the Russian leader's health. Morell and Mowatt-Larssen also discuss Western involvement in the conflict and the lingering potential for the Kremlin to use weapons of mass destruction. 

By many measures, Russia’s state-controlled nuclear energy company, Rosatom, has primacy in the global nuclear energy market. At any given moment, the firm provides technical expertise, enriched fuel, and equipment to nuclear reactors around the world. The Russian invasion of Ukraine and, more acutely, the Russian military’s dangerous actions at the Zaporizhzhia nuclear power plant and in the Chernobyl exclusion zone have many countries rethinking their dependence on Russian nuclear products and searching for alternatives. Additionally, the ensuing global effort to cripple Russian access to international markets calls into question the viability of current contracts, government licensing, and financial instruments involved in Russia’s nuclear exports.

Hamidreza Azizi and Nicole Grajewski analyze Russian Foreign Minister Sergei Lavrov's recent demands  for written guarantees that Western sanctions over Ukraine "will by no means affect our right to free and full-fledged trading, economic, investment, military and technical cooperation with Iran."

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

What sounded so simple during last year’s presidential campaign has turned out, like everything related to Iran, to be quite complicated.

A comparative analysis of the United States’ and the Soviet Union’s previously underexplored radiological weapons programs identifies the drivers behind their rise and demise. The findings of this analysis illuminate the factors likely to affect the pursuit of radiological weapons by other states in the future.

Despite the continuing debate in Tehran, the principle of “no negotiation under pressure” with the United States remains a consensual principle among all members of the current regime. The Supreme Leader has expressed this position by stating that the negotiations with the Trump administration are “double poison”. While Iran’s regional enemies are pushing for confrontation, the international community remains supportive of Tehran’s political position, as long as it stays committed to the nuclear deal. Existing indicators do not point at any willingness for confrontation from either side – at least at the moment. And although some regional actors have attempted to pacify the tension, the prospects for a truce remain unlikely within the current context.
