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.

After viewing the movie Oppenheimer, Matthew Bunn, John P. Holdren, Mariana Budjeryn, Matthew J. Parent, Calder Walton, Sylvia Mishra, and Julie George offer their thoughts on its relevance to the world today. 

Scott Sagan asked Joseph S. Nye to revisit Nuclear Ethics, a book he published in 1986, in light of current developments in world affairs. In doing so, he found that much had changed but the basic usability paradox of nuclear deterrence remains the same. 

Joseph Nye writes that even at this early stage, there are at least eight lessons— some old, some new— that the world is learning (or relearning) from the war in Ukraine.

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.

On August 6, 1945, the United States dropped an atomic bomb on Hiroshima, Japan, launching the nuclear age. On the 75th anniversary of that somber event, Belfer Center experts reflect on the event and its aftermath. 

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.

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?

It seems unlikely that Russia will again possess the resources to balance U.S. power in the same way that the Soviet Union did during the four decades after World War II. But declining powers merit as much diplomatic attention as rising ones do. Joseph S. Nye worries that the United States lacks a strategy to prevent Russia from becoming an international spoiler.

Joseph Nye writes that In the cyber realm, the same program can be used for legitimate or malicious purposes, depending on the user’s intent. But if that makes traditional arms-control treaties impossible to verify, it may still be possible to set limits on certain types of civilian targets and negotiate rough rules of the road that limit conflict.
