Henry Kissinger – longtime scholar and diplomat – died on Wednesday, November 29. Several Belfer Center foreign policy and security experts share their thoughts on the impact Kissinger has had on the U.S., the world, and on themselves.

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.

Joseph Nye writes that Washington's strategy towards Beijing should be to avoid either a hot or cold war, co-operate when possible and marshal its assets to shape China's external behaviour. This can be done through deterrence and a strengthening of both alliances and international institutions.

In the absence of an alternative shorthand, politicians and journalists most likely will continue to use "Global South" for the foreseeable future. Yet anyone interested in a more accurate description of the world should be wary of such a misleading and increasingly loaded term.

Joseph Nye writes that if the United States maintains its alliances, invests in itself, and avoids unnecessary provocations, it can reduce the probability of falling into either a cold war or a hot war with China. But to formulate an effective strategy, it will have to eschew familiar but misleading historical analogies.

Joseph S. Nye writes that following the first Republican debate of the U.S. presidential primary season, there is good reason to worry about what a Republican victory in 2024 would mean for the U.S.-led global order. History suggests that when Americans embrace retrenchment, much more than just liberal internationalist principles suffer for it.

Joseph Nye argues that official statements about India and America's "shared values" do not make an alliance. Following the basic logic of balance-of-power politics, India and the United States seem fated not for marriage but for a long-term partnership — one that might last only as long as both countries remain preoccupied with China.

This primer provides a concise background of three major elements of the Biden administration’s Indo-Pacific Strategy: the Quad, a non-traditional multilateral grouping of India, Japan, Australia, and the U.S.; the AUKUS security pact between Australia, the United Kingdom, and the U.S.; and the Partners in the Blue Pacific, a multilateral initiative aimed at promoting greater alignment with the Pacific Island nations. 

Joseph Nye explores what a second Donald Trump presidency may mean for U.S. foreign policy and the world? While the man himself is unpredictable, his first term and his behavior since losing re-election in 2020 offer plenty of clues, none of which would be comforting to America's allies.

Scott Sagan asked Joseph S. Nye to revisit Nuclear Ethics, a book he published in 1986, in light of current developments in world affairs. In doing so, he found that much had changed but the basic usability paradox of nuclear deterrence remains the same.
