Nuclear Issues

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war. 

Stephen Walt analyses the past thirty years of U.S. foreign policy toward the Middle East, focusing on five events.

With rational decision-making, the likelihood of strategic nuclear exchange should be zero. But emotions can create uncertainty, contradicting the expectations of the rational cost-benefit assumptions undergirding deterrence theory.

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.

Jayita Sarkar explains why the Biden administration needs to re-conceptualize nuclear terrorism and act quickly.

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.    

In 2011, the International Atomic Energy Agency (IAEA) released the fifth revision of its Nuclear Security Recommendations on Physical Protection of Nuclear Material and Nuclear Facilities. This update of IAEA nuclear security guidance was a significant improvement upon its predecessors, suggesting new and strengthened approaches to nuclear security in a range of areas. Nearly a decade later, however, the global nuclear security landscape has changed. Nuclear security regulations and practices have improved. International institutions and norms supporting global nuclear security architecture are stronger. Countries have made new political commitments to strengthening their nuclear security. Legally binding agreements are more widely subscribed than they were before. Meanwhile, new global threats have surfaced, presenting new challenges to physical protection systems. A range of emerging technologies creates new opportunities, but also new risks.

Edited by former Project on Managing the Atom (MTA) Associate Jon Wolfsthal and featuring papers authored by Wolfsthal and MTA Associate Nickolas Roth, this report from the American Nuclear Policy Initiative details the Trump administration's first three years of efforts on nuclear proliferation, strategic stability, nuclear modernization, Iran, and North Korea. The authors provide an objective summary of nuclear policy under the current administration and its record on protecting the United States and its allies against perhaps the greatest national security danger facing humanity.

A nuclear explosion detonated anywhere by a terrorist group would be a global humanitarian, economic, and political catastrophe. The current COVID-19 pandemic reminds us not to ignore prevention of and preparation for low-probability, high-consequence disasters. For nuclear terrorism, while preparation is important, prevention must be the top priority. The most effective strategy for keeping nuclear weapons out of the hands of terrorists is to ensure that nuclear materials and facilities around the world have strong and sustainable security. Every president for more than two decades has made strengthening nuclear security around the globe a priority. This includes the Trump administration, whose 2018 Nuclear Posture Review states: “[n]uclear terrorism remains among the most significant threats to the security of the United States, allies, and partners.”
