Nuclear Issues

Calder Walton says both seek to topple the United States from atop world stage, with China's blend of money, influence, all-hands-on-deck approach posing the greater threat.

Belfer Center experts on the U.S.-China relationship and Middle East issues shared thoughts on the significance of the unexpected Iran-Saudi Arabia agreement brokered by China. 

 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.

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

The Bulletin of Atomic Scientists has published a document from the Pugwash Conference on Science and World Affairs concerning nuclear problems and tensions in the time of COVID-19. The document has been co-signed by a large number of Pugwash colleagues and personalities.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

Joseph Nye writes that some decoupling of interdependence is likely, particularly in areas related to technology that directly affect national security. But will Washington and Beijing go too far?

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

Julius Weitzdörfer’s earliest childhood memories are the major global events of 1986—the Space Shuttle Challenger explosion and the Chernobyl disaster. Looking back, he realizes that these events must have contributed to shaping his later research interests in managing technological risks.
