Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war. 

Peaking great powers facing a slowdown in growth are likely to try to violently shake up the world. These findings amend classic theories of great power conflict. They help explain some of the most consequential geopolitical events in modern history. And they have ominous implications for contemporary Chinese foreign policy. 

After the mistaken U.S. bombing of the Chinese Embassy in Belgrade in 1999, China turned to information-age weapons to create a risk of escalation to nuclear war with the United States. This shift helps compensate for its conventional military inferiority.

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

Why would a state that lacks nuclear weapons choose to fight a state that has them? In this roundtable, four scholars evaluate Paul Avey's explanation for this phenomenon.

As the novel coronavirus continues spreading, the whole world is preparing for the onslaught in similar ways—social distancing, working from home, panic buying at grocery stores. But people in different countries are also weathering this crisis in different ways, finding, for example, different products to hoard, different ways to pass the time, different people to blame and even different things to worry about.

SWJ interview with Nathaniel L. Moir, Ph.D., an Ernest May Postdoctoral Fellow in History and Policy at the Belfer Center for Science and International Affairs, Harvard Kennedy School. Dr. Moir is completing a book manuscript on Bernard Fall for publication.

China and the United States hold opposing beliefs about whether nuclear war can be avoided in a potential crisis or armed conflict. Taken together, these opposing beliefs increase the risk of nuclear escalation and can lead to greater crisis instability.

What explains the scale and speed of nuclear proliferation? One key factor is the level of competition among suppliers in the market for nuclear materials and technologies. When suppliers form a cartel, fewer countries can acquire what they need for a nuclear weapons program. If great power competition intensifies, suppliers will find it harder to cooperate and nuclear proliferation could accelerate.
