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.

The global demand for desalinated water is increasing at a remarkable rate. In a future with increasing demand for water and low-carbon electricity, an interesting ecological dilemma emerges. In a decarbonized world, providing desalinated water for domestic use and aquatic ecological restoration could increasingly come at the expense of open space lost to renewables such as solar photovoltaics (PV) and wind turbines. In this article we examine the environmental tradeoffs of providing freshwater from desalination under a solar photovoltaic-based decarbonization strategy, using Israel as an example.

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 ongoing COVID-19 pandemic is upending our lives and the global economy in ways unimaginable until recently. While the overall impacts are still difficult to quantify, ramifications are sure to be felt for decades to come. Providing secure, reliable, and affordable resources for all without causing devastating environmental consequences is perhaps the greatest challenge of the 21st century. But the pandemic has significantly altered dynamics and changed priorities. How is this impacting the quest for sustainability?

In this paper we analyze these challenges by focusing on the plastic industry. There is no doubt that plastic has molded society in many ways that make our lives easier and safer, but it has also created a global environmental and sustainability crisis. In order to curb our addiction to plastic, the world had been waging a war against virgin plastic, but the pandemic has turned an enemy into a much-needed ally. How can we leverage the advantages of plastic without contributing to the world’s environmental crisis? This dilemma poses a significant challenge, but also opens an opportunity to address sustainability at a systemic level through circularity and the transition to low-carbon alternatives to petroleum-based plastics.

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. 

The peer-reviewed update of ENRP's ongoing research on renewable hydrogen is featured in the June volume of Geopolitics, History, and International Relations, an academic journal of which Dr. Nicola de Blasio is now also an editor.
