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.

The Peril of Peaking Powers: Economic Slowdowns and Implications for China’s Next Decade

| Summer 2023

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.

| Fall 2022

The world’s oceans have always provided ships with room to hide. New technology is changing that. Small satellites now collect terabytes of global data daily. Computational analytics can mine that data as humans cannot. Increasingly, this information expands the ability to identify and track ships and their activities, including those affecting national and international security.

Strategic Substitution: China’s Search for Coercive Leverage in the Information Age

    Author:

| Summer 2022

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.

Negative Security Assurances After Russia’s Invasion of Ukraine

| July 07, 2022

On February 24, the international community took a catastrophic blow. Already battered by two years of the COVID-19 pandemic and deteriorating interstate relations, it stood in horror as Russian forces unleashed an unprovoked war on a neighboring country. Russia’s decision to invade Ukraine and reject Ukraine’s very existence as a separate state is ominous and highly momentous for the future of the world order.

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.

Cologne Sanitizer, Boxed Wine and Bidets: How People in 68 Countries Are Coping With Coronavirus

| Mar. 22, 2020

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.

Dangerous Confidence? Chinese Views on Nuclear Escalation

    Authors:
  • Fiona S. Cunningham

| 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.

Going it Alone: The Causes and Consequences of U.S. Extraterritorial Counterproliferation Enforcement

| Mar. 25, 2019

In 2004, the United Nations Security Council adopted resolution 1540, which acknowledged the non-state acquisition of weapons of mass destruction as a security threat and called on member states to implement “appropriate effective” domestic trade controls. The United States, however, has both promoted the multilateral implementation of strategic trade controls but has also increasingly resorted to extraterritorial enforcement of its counterproliferation rules. How can a multilateral, norms-based international regime like 1540 contend with extraterritorial enforcement based on national interests? We argue that increased U.S. extraterritorial counterproliferation policies are a consequence of the inconsistent implementation of resolution 1540, adaptive and resilient proliferation networks, and a history of expanding legal interpretations of jurisdiction. We find that while U.S. extraterritorial enforcement can effectively disrupt networks hiding in overseas jurisdictions, doing so creates disincentives for states to implement 1540 obligations and undermines broader nonproliferation objectives.
