A “Nuclear Umbrella” for Ukraine? Precedents and Possibilities for Postwar European Security

| Winter 2023/24

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.

Defending the United States: Revisiting National Missile Defense against North Korea

| Winter 2021/22

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.

The End of Cyber-Anarchy?

| January/February 2022

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.

Biden to Putin in Geneva: There's a New Sheriff in Town.

| June 17, 2021

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

The 2018 National Defense Strategy (NDS) is predicated on a single organizing principle: America’s military pre-eminence is rapidly eroding. This is not a new concept. For years, experts have warned that the economic and technological advancements of U.S. adversaries, coupled with the 2008 financial crisis and America’s focus on peripheral conflicts, have caused a decline in America’s military dominance. 

In this context, the advances of near-peer competitors such as China and Russia have created plausible “theories of victory” in potential conflicts across Eastern Europe and East Asia. Competitors’ unaddressed improvements in strategic innovation, economic investment, and dual-use technology increases the risk of conflict and strains the U.S. alliance system. It is urgent that the United States reestablish and maintain credible deterrents against these near-peer competitors. After decades of focusing on post-Cold War ‘shaping’ operations, the American military needs to reinvigorate for full spectrum great power competition.

This report is intended as a blueprint on how to begin that process from graduate students at the Belfer Center for Science and International Affairs at Harvard University. Contained inside are 12 memorandums. Each provides a high-level overview and specific recommendations on a key issue of American defense policy.

| Fall 2019

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.
