Nuclear Issues

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

Why do we think Vladimir Putin will not use “the bomb” when there is so much evidence that he will?

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.    

Every president serving in the last two decades has said that nuclear terrorism is a significant national security threat. Analysis of this threat has been, for good reason, mostly focused on foreign extremist groups, but recent events raise questions of whether there should be greater focus in the United States on far-right, domestic extremist threats. These extremists represent a unique danger because of their prevalence in federal institutions such as the military and the potential that they might infiltrate nuclear facilities, where they could access sensitive information and nuclear materials.

How do presidents incorporate morality into decisions involving the national interest? Moral considerations explain why Truman, who authorized the use of nuclear weapons in Japan during World War II, later refused General MacArthur's request to use them in China during the Korean War. What is contextual intelligence, and how does it explain why Bush 41 is ranked first in foreign policy, but Bush 43 is found wanting? Is it possible for a president to lie in the service of the public interest? In this episode, Professor Joseph S. Nye considers these questions as he explores the role of morality in presidential decision-making from FDR to Trump.

International concern over nuclear terrorism has grown during the past few decades. This has driven a broad spectrum of efforts to strengthen nuclear security globally, including the widespread adoption of radiation-detection technology for border monitoring. Detection systems are now deployed at strategic locations for the purported purpose of detecting and deterring the smuggling of nuclear and radioactive materials. However, despite considerable investment in this area, few studies have examined how these programs are implemented or the operational challenges they face on a day-to-day basis. This article seeks to address this with a focus on radiation-detection efforts at maritime facilities. Utilizing practitioner interviews and a survey, this article identifies the factors that influence the planning and use of these systems in this fast-moving environment. The results clearly demonstrate that the implementation of these systems varies significantly across different national and organizational contexts, resulting in a fragmented global nuclear-detection architecture, which arguably undermines efforts to detect trafficked nuclear-threat materials. Greater consideration should therefore be given to developing international standards and guidance, designing and adopting tools to support key parts of the alarm assessment process, and broader sharing of good practice.
