Nuclear Issues

David Kearn argues that even in the absence of restrictive resource and budgetary constraints, a focus on identifying and achieving concrete objectives that will position the United States and its allies to effectively deter aggression in critical regional flashpoints should be the priority given the stressed nature of the defense industrial base and the nuclear enterprise.

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

David W. Kearn argues that deployment of nuclear weapons cannot rectify a perceived imbalance in conventional forces in the western Pacific.

According to the "Madman Theory" outlined by Daniel Ellsberg and Thomas C. Schelling, and embraced by Presidents Richard Nixon and Donald Trump, being perceived as mad can help make seemingly incredible threats—such as starting a nuclear war—more credible. However, recent research has largely concluded that the Madman Theory does not work. 

 Stephen Walt decided to look back to see if 2022 had gone according to his expectations. In his last column of 2021, he had described "Biden’s 2022 Foreign-Policy To-Do List." What did he get right, what did he get wrong, and how well did the Biden administration perform?

Stephen Walt provides A realist POV on the war in Ukraine, competition with China, COVID, and more in the second part of an interview with Foreign Policy Editor-in-Chief Ravi Agrawal.

Jayita Sarkar outlines a series of measures the administration could take, such as providing assistance to victims of radiation, that would advance the Treaty on the Prohibition of Nuclear Weapons’s agenda but do not require complete adherence.

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.

Carpenter and Montgomery replicate a key question from Sagan and Valentino’s landmark survey of U.S. attitudes toward the laws of war and introduce variations into Sagan and Valentino’s experiment. The findings reveal Americans’ strong belief that targeting civilians is wrong, and that a majority would likely oppose such action in real life.

Scott Sagan and Benjamin Valentino, and Charli Carpenter and Alexander Montgomery continue the debate on the power of noncombatant immunity norms, discuss how scholars should approach the study of these norms, and emphasize their shared objective to determine how security norms can be bolstered rather than undermined.
