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.

Judging Henry Kissinger

| Nov. 30, 2023

Joseph S. Nye writes that evaluating ethics in international relations is difficult, and Kissinger's legacy is particularly complex. Over his long tenure in government, he had many great successes, including with China and the Soviet Union and the Middle East. Kissinger also had major failures, including in how the Vietnam War ended. But on net, his legacy is positive. In a world haunted by the specter of nuclear war, his decisions made the international order more stable and safer.

Solving the Mystery of Henry Kissinger's Reputation

| June 09, 2023

Stephen Walt critiques Henry Kissinger's professional life by dividing it into three parts: as an academic at Harvard; as national security advisor and secretary of state; and as an author, pundit, and sage, much of it conducted as the head of Kissinger Associates, the consulting firm he founded after leaving government.

| Spring 2023

South Korean President Yoon Suk Yeol visited Harvard on April 28 and delivered a major policy speech at Harvard Kennedy School’s JFK Jr. Forum. Following his speech, President Yoon joined Harvard Distinguished Service Professor Joseph Nye for a conversation about security and soft power derived from the country's cultural strength. He also took questions from the large audience of students and others attending the event in person and online.

The Belfer Center’s Korea Project worked closely with Harvard University colleagues and Korean Consulate General counterparts to arrange for the visit and the Harvard speech, the first for a sitting South Korean president. The Kennedy School's Institute of Politics and the Korea Project co-sponsored the historic speech.

Distressing a system in distress: global nuclear order and Russia’s war against Ukraine

| Nov. 08, 2022

While prosecuting its invasion of Ukraine, Russia has relied heavily on nuclear threats, turning the war in Ukraine into a dangerous nuclear crisis with profound implications for the global nuclear order and its two constitutive systems of nuclear deterrence and nuclear restraint. These two interconnected systems, each aiming to manage nuclear possession and reduce the risk of nuclear use, are at once complimentary and contradictory. While tensions between these systems are not new, the war in Ukraine exacerbates them in unprecedented ways. The system of nuclear deterrence seems to be proving its worth by inducing restraint on Russia and NATO, while the system of restraint is undermined by demonstrating what happens to a country not protected by nuclear deterrence. The latter lesson is particularly vivid given Ukraine’s decision to forgo a nuclear option in 1994 in exchange for security assurances from nuclear powers. Russia’s use of nuclear threats as an enabler for escalation and the specter of Russian tactical nuclear use against Ukraine goes well beyond its declared nuclear doctrine. The outcome of the war in Ukraine thus has critical importance for deciding the value of nuclear weapons in global security architecture and for resolving the conundrum between the systems of deterrence and restraint.
