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.

Cyber attacks are both exciting and terrifying, but the ongoing obsession with ‘cyber warfare’ clouds analysis and hampers strategy development. Much commentary and analysis of cyber conflict continues to use the language of war, where actors use ‘offensive cyber operations’ to meet adversaries in ‘engagements’ striving for victory on the ‘battlefield’ in the ‘cyber domain’. This discourse persists despite a growing consensus that cyber operations are primarily relevant in conflict short of war.

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.

Although cyber conflict has existed for thirty years, the strategic utility of cyber operations remains unclear. The subversive trilemma explains why cyber operations tend to fall short of their promise in both warfare and low-intensity competition.

As the United States emerges from the era of so-called forever wars, it should abandon the regime change business for good. Then, Washington must understand why it failed, writes Stephen Walt.

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. 

America’s botched response to the coronavirus pandemic is a warning that, unless our broken political and administrative systems are fixed, the country could experience a similar breakdown in future national crises, such as a massive cyberattack.
