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 Future World Order: New Online Event Series from the Belfer Center's International Security Program

| Sep. 21, 2020

The existing global political-economic order has been ruptured by the rise of China, a broad backlash against globalization, uncertainties about the U.S. commitment to a rules-based system, and most recently, the Covid-19 pandemic. What form(s) might a future world order take, and what principles should guide efforts to construct it? The Future World Order event series will address these questions by examining individual topics ranging from traditional security issues such as arms control to newer, relevant issues such as digital trade. Professors Dani Rodrik and  Stephen M. Walt will moderate individual sessions.

The Global Order After COVID-19

| 2020

Despite the far-reaching effects of the current pandemic,  the essential nature of world politics will not be transformed. The territorial state will remain the basic building-block of international affairs, nationalism will remain a powerful political force, and the major powers will continue to compete for influence in myriad ways. Global institutions, transnational networks, and assorted non-state actors will still play important roles, of course, but the present crisis will not produce a dramatic and enduring increase in global governance or significantly higher levels of international cooperation. In short, the post-COVID-19 world will be less open, less free, less prosperous, and more competitive than the world many people expected to emerge only a few years ago.

IAEA Nuclear Security Recommendations (INFCIRC/225): The Next Generation

In 2011, the International Atomic Energy Agency (IAEA) released the fifth revision of its Nuclear Security Recommendations on Physical Protection of Nuclear Material and Nuclear Facilities. This update of IAEA nuclear security guidance was a significant improvement upon its predecessors, suggesting new and strengthened approaches to nuclear security in a range of areas. Nearly a decade later, however, the global nuclear security landscape has changed. Nuclear security regulations and practices have improved. International institutions and norms supporting global nuclear security architecture are stronger. Countries have made new political commitments to strengthening their nuclear security. Legally binding agreements are more widely subscribed than they were before. Meanwhile, new global threats have surfaced, presenting new challenges to physical protection systems. A range of emerging technologies creates new opportunities, but also new risks.
