Matthew Evangelista examines the precedents and possibilities for postwar European security in an interview with International Security Executive Editor Jacqueline L. Hazelton.

In this Q&A, Joseph S. Nye talks about his advice for the interim and future president of Harvard in the wake of Claudine Gay's resignation, which countries should be highest on our radar to prevent the threat of nuclear war, what role the U.S. should play in the Russia-Ukraine war, the significance of U.S. alliances in the Middle East, and more.

Calder Walton recounts how Russia and China are using their intelligence agencies to reverse the outcome of the Cold War

Commercial international port terminals owned and operated by Chinese firms provide dual-use capabilities to the People's Liberation Army during peacetime. They enable China to project power into critical regions worldwide by providing military logistics and intelligence networks.

As conventional wisdom goes, experts tend to rank the U.S ahead of China, U.K., Iran, North Korea, Russia, in terms of how strong it is when it comes to cyberspace. But a new study from Harvard University’s Belfer Center shows that China has closed the gap on the U.S. in three key categories: surveillance, cyber defense, and its efforts to build up its commercial cyber sector.

“A lot of people, Americans in particular, will think that the U.S., the U.K., France, Israel are more advanced than China when it comes to cyber power,” Eric Rosenbach, the Co-Director of Harvard’s Belfer Center, told CyberScoop. “Our study shows it’s just not the case and that China is very sophisticated and almost at a peer level with the U.S.”

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

The Belt and Road Initiative (BRI) is an important cooperative framework that increasingly affects the global economy, trade, and emission patterns. However, most existing studies pay insufficient attention to consumption-based emissions, embodied emissions, and non-CO2 greenhouse gases (GHGs). This study constructs a GHG emissions database to study the trends and variations in production-based, consumption-based, and embodied emissions associated with BRI countries

A simplified nuclear exchange model demonstrates that China’s ability to launch a successful nuclear retaliatory strike in response to an adversary’s nuclear first strike has been and remains far from assured. This study suggests that China’s criterion for effective nuclear deterrence is very low.

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.

Over the past quarter century, nearly all major efforts at establishing a durable post–Cold War order on the Eurasian continent have foundered on the shoals of Ukraine. For it is in Ukraine that the disconnect between triumphalist end-of-history delusions and the ongoing realities of great-power competition can be seen in its starkest form.
