The Nuclear Balance Is What States Make of It

Recent quantitative scholarship uses warhead counts to examine whether nuclear superiority offers political or military benefits beyond having a secure second-strike capability. These analyses overlook other elements of a state’s nuclear capability such as state perceptions and beliefs.

South Korea's conventional counterforce and countervalue strategy is meant to hold North Korea’s nuclear weapons infrastructure, as well as its leadership, at risk independently from the United States. This strategy is often overlooked by policymakers and analysts, who are more focused on discussing Kim Jong Un’s pledges to develop new missile and nuclear capabilities and how the new administration of President Joe Biden should approach the nuclear issue. However, as we highlight in a new article in International Security, South Korea’s strategy increasingly has a determining impact on strategic stability on the Korean Peninsula and on prospects for denuclearization.

| Winter 2020/21

South Korea’s conventional counterforce and countervalue strategy is a manifestation of its uncertainties over the reliability of the U.S. alliance. This strategy has significant implications for strategic stability and the potential for denuclearization on the Korean Peninsula.

The TPNW, Equity, and Transforming the Nuclear Community: An Interview with Nuclear Scholar Dr. Aditi Verma

    Author:
  • Laura Grego
| Jan. 21, 2021

In anticipation of the entry into force of the landmark Treaty on the Prohibition of Nuclear Weapons (TPNW) on Friday, Laura Grego corresponded with Dr. Aditi Verma, a Stanton Nuclear Security Postdoctoral Fellow at the Harvard University Belfer Center’s Project on Managing the Atom and the International Security Program.  Dr. Verma, who holds undergraduate and doctoral degrees in Nuclear Science and Engineering from MIT, is broadly interested in how nuclear technologies can be designed in collaboration with publics such that traditionally excluded perspectives can be brought into these design processes. She’s one of the five authors of the essay, “A call for antiracist action and accountability in the US nuclear community.”

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.

China’s Nuclear Security: Progress, Challenges, and Next Steps

| March 28, 2016

In a new report from the Project on Managing the Atom, Senior Research Associate Hui Zhang finds that China has made important nuclear security improvements in areas ranging from its legal framework, to its approaches to physical protection and material accounting, to bolstering nuclear security culture. But China also faces ongoing threats. The possibility of insider theft of nuclear materials in China cannot be ruled out, espe­cially as China increasingly grows into a market-oriented society contending with corruption. Zhang also notes that Beijing faces a growing terrorism threat from separatists in China’s autonomous Xinjiang region.

The Cost of Reprocessing in China

| January 2016

Faced with the twin pressures of a still-quickly growing economy and unprecedented smog from coal-fired plants, China is racing to expand its fleet of nuclear power plants. As it does so, Beijing is considering making large capital investments in facilities to reprocess spent nuclear fuel and recycle the resulting plutonium in fast neutron reactors that breed more plutonium. This report outlines the enormous costs China would likely face if it decides to build large-scale plants for reprocessing plutonium from spent nuclear fuel and recycling the plutonium in fast neutron reactors.

The Middle East After the Iran Nuclear Deal: Chuck Freilich

| September 7, 2015

"A takeover of Syria by the self-proclaimed Islamic State or Syrian rebel groups would also prove dangerous. Heinous as it is, Bashar al-Assad's regime still has many assets to lose in a confrontation with Israel and can thus be deterred. It will take time for non-state actors to develop similar assets."
