Russia and the Global Nuclear Order

| March 2024

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.

The Global Order After COVID-19

| 2020

Despite the far-reaching effects of the current pandemic,  the essential nature of world politics will not be transformed. The territorial state will remain the basic building-block of international affairs, nationalism will remain a powerful political force, and the major powers will continue to compete for influence in myriad ways. Global institutions, transnational networks, and assorted non-state actors will still play important roles, of course, but the present crisis will not produce a dramatic and enduring increase in global governance or significantly higher levels of international cooperation. In short, the post-COVID-19 world will be less open, less free, less prosperous, and more competitive than the world many people expected to emerge only a few years ago.

The Strategic Postures of China and India: A Visual Guide

| March 2020

Fueled by aggressive rhetoric from both capitals, Indian and Chinese ground forces engaged in a standoff between June and August 2017. The Doklam crisis, as it became known, stimulated introspection among officials and experts in both states about the future of their relationship. Politically, both strategic communities largely concluded that the peaceful resolution of border disputes is now less likely, forecasting more rivalry than cooperation. Militarily, Indian discussions on the strength of its military position against China in their disputed ground frontier areas have converged on the view that China holds the conventional and nuclear edge over India in this domain.

Based on our analysis of data on the location and capabilities of Indian and Chinese strategic forces and related military units, we conclude that this assessment of the balance of forces may be mistaken and a poor guide for Indian security and procurement policies. We recommend that instead of investing in new nuclear weapons platforms that our analysis suggests are not likely to be required to deter China, New Delhi should improve the survivability of its existing forces and fill the gap in global arms control leadership with an initiative on restraint and transparency.

A Theory of Engagement With North Korea

| May 2019

At the Hanoi Summit in February 2019, the United States and North Korea reached a familiar impasse—diplomacy broke down over the appropriate order of near-term steps, and the world was left wondering whether any package of rewards would be enough to incentivize denuclearization.

In a new Managing the Atom Discussion Paper, Christopher Lawrence outlines an alternative conceptual framework for engaging North Korea. Rather than offering rewards for nuclear rollback, the approach focuses on building credibility around the notion of a shared political future. Lawrence suggests that physical actions—such as shared investments in integrated rail, electricity, or mining infrastructure—speak more credibly about the political future for all the parties involved than do written commitments or more transient “carrots” and “sticks.” The international relationships created by infrastructure projects may alter North Korea's security calculus over time, and incrementally reduce its dependence on nuclear weapons. Drawing lessons from the 1994 Agreed Framework, Lawrence reinterprets the history of nonproliferation engagement with North Korea, and illuminates possible opportunities to break the diplomatic impasse after the Hanoi summit.

The Iran Nuclear Archive: Impressions and Implications

In mid-January, a team of scholars from the Belfer Center’s Intelligence and Managing the Atom Projects traveled to Tel Aviv, Israel to examine samples of, and receive briefings on, an archive of documents related to Iran’s nuclear weapons program. The large cache includes some 55,000 pages of documents and a further 55,000 files on CDs that included photos and videos. A clandestine Israeli intelligence operation spirited the materials out of Iran in early 2018.

The documents that the Belfer group were shown confirm that senior Iranian officials had decided in the late 1990s to actually manufacture nuclear weapons and carry out an underground nuclear test; that Iran’s program to do so made more technical progress than had previously been understood; and that Iran had help from quite a number of foreign scientists, and access to several foreign nuclear weapon designs. The archive also leaves open a wide range of questions, including what plan, if any, Iran has had with respect to nuclear weapons in the nearly 16 years since Iran’s government ordered a halt to most of the program in late 2003. 

This brief report summarizes the group’s conclusions about what the archive reveals about Iran’s program and questions that remain open.

Revitalizing Nuclear Security in an Era of Uncertainty

| January 2019

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

On China's Closed Fuel Cycle Strategies

| July 2018

As it expands its fleet of nuclear power plants, China faces an important decision: whether to make large capital investments in facilities to reprocess spent nuclear fuel and recycle the resulting plutonium in fast neutron reactors, or continue to store nuclear fuel, leaving for the future decisions on whether to reprocess the fuel or dispose of it as waste. In reaching a decision, policymakers should consider financial costs, the available fuel supply, nuclear security and proliferation risks, health and environmental dangers, and spent fuel management issues. This paper will first discuss the status of China’s breeder reactors and civilian reprocessing programs. It will then examine the costs and fuel supply issues associated with reprocessing.

China’s Fissile Material Production and Stockpile

| January 2018

China began producing highly enriched uranium (HEU) and plutonium for nuclear weapons in the 1960s and is believed to have halted production the 1980s. Despite the passage of thirty years there has been no official policy declaration in this regard. This report uses newly available public information from Chinese sources to provide an improved reconstruction of the history of China’s production of HEU and plutonium for nuclear weapons. This allows improved estimates of the amount of HEU and plutonium China has produced and of its current stockpiles.

Steps for Rebuilding U.S.-Russian Nuclear Security Cooperation

| July 2017

Cooperation between U.S. and Russian nuclear scientists and engineers represents an important opportunity for rebuilding U.S.-Russian relations. The United States and Russia possess more than 90 percent of the world’s nuclear weapons, the world’s largest stocks of weapons-usable nuclear material, and the world’s largest nuclear complexes, giving them a special responsibility for nuclear security and preventing nuclear terrorism.
