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.

Ukraine’s Defense: A Whole-of-Society Effort Demanding Additional Support

| Oct. 13, 2023

For Ukraine to maintain its defense and decisively thwart Russia’s invasion, it will take steadfast commitments from Western allies providing both state-of-the-art equipment and basic warfighting needs, local industry leaders and factory workers readying equipment for the frontlines and developing innovative technologies, and civilian volunteers tirelessly filling in the remaining gaps.

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.

| Apr. 23, 2023

Around the world, the United States relies heavily on security assistance to gain influence and make its allies more formidable. When actual war breaks out, however, many long-time recipients of such assistance fight poorly or otherwise do not seem to have heeded the lessons that U.S. trainers tried to impart. The Naval War College’s Rachel Tecott Metz examines this track record, arguing that the United States relies too much on teaching and persuasion and should instead emphasize conditionality more.

Report: Marking the CIA’s 75th Anniversary: Reflections on the Past, Visions of the Future

Since its creation in 1947, the Central Intelligence Agency (CIA) has been at the heart of supporting United States foreign policy and national security decision-making. From the early days of the Cold War to Russia’s war against Ukraine, the CIA has been a critical instrument of foreign intelligence collection, analysis, and operations. However, the CIA is often misunderstood, as its own work and history, particularly its successes, are rarely seen by the public. To help unpack this storied history, and in honor of the agency’s 75th anniversary, on September 16, 2022, former directors, officers, scholars, students, and the public gathered to discuss the past, present, and future of the agency.

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.
