Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

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.

This report, by Maxwell Simon (MPP '23) and Jayaram Ravi (MPP '23), explores the drivers of setback and success that China has encountered in the process of developing dual-use and military-dedicated naval installations abroad. It looks at cases where China has considered or actively pursued military-dedicated installations to characterize Beijing’s general approach to overseas naval base acquisition.

Foreign Affairs has recently published a number of articles on how the United States should engage with the Taliban government in Afghanistan, extremist forces within the regime, how the West can help ordinary Afghans, and the fate of the country’s women. To complement these essays, Foreign Affairs asked a broad pool of experts for their take. As with previous surveys, Foreign Affairs approached dozens of authorities with expertise relevant to the question at hand, along with leading generalists in the field. Participants were asked to state whether they agreed or disagreed with a proposition and to rate their confidence level in their opinion. Two Belfer Center experts participated, International Security Executive Editor Jacqueline L. Hazelton and Future of Diplomacy Project Senior Fellow Paula Dobriansky.

Legionnaire recruitment is a function of political constraints on a government's ability to enlist citizens and its perceptions of external territorial threats.

What sounded so simple during last year’s presidential campaign has turned out, like everything related to Iran, to be quite complicated.

In order to fully appreciate the global climate-change challenge that the Biden administration will face, Robert Stavins reflects on the history of international negotiations that brought us to this point.

Nathaniel L. Moir reviews Antonio Giustozzi's The Taliban at War: 2001–2018 (New York: Oxford University Press, 2019).  He writes, "Through an assessment of the intra-politics of the Taliban's different shuras, along with the success and failures these shuras have achieved over the recent past, Giustozzi brings readers up to date on the Taliban's organizational status as it moved toward negotiations with the Afghan government."

Henry Kissinger warns that many existing domestic and international institutions that have helped govern the past decades will not survive the Covid-19 crisis. He is surely correct.

Former U.S. Secretary of State Rex Tillerson offered his take on global leaders and hotspots, from Iran and Saudi Arabia to North Korea and Syria. He was joined by Professor Nicholas Burns, Professor James Sebenius and Professor Robert Mnookin.
