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.

The powerful effects of artificial intelligence are already being felt in business, politics, medicine, war, and almost every other domain of twenty-first century life. For all of its positive potential, the technology presents significant risks that are best addressed sooner rather than later.

Amy Ertan and Tarah Wheeler describe how the World Health Organization is uniquely positioned to help secure all facets of vaccine information.

Joseph Nye writes that with less preponderance and facing a more complex world, the United States must exercise power with as well as over others and use its soft power to attract their cooperation. To do that, the United States will have to rediscover the importance of the institutions Donald Trump's administration abandoned.

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. 

Joseph Nye writes that the institutional costs of using a wrecking ball approach may reduce American power in the long run.
