Joseph Nye argues that the "one China" formula, if combined with other measures to bolster deterrence against any sudden acts of aggression, can still help to keep the peace.

Only a small handful of people in the world have sat at the negotiating table with the North Koreans and extensively interacted with them. Yet, this knowledge is fragmented and has not been collected or analyzed in a systematic manner. This report captures the findings from in-depth, one-on-one interviews with former senior negotiators from the United States and South Korea, who gained unique knowledge about North Korean negotiating behavior by dealing directly with their high-level North Korean counterparts. 

These negotiators collectively represent a body of negotiation experience and expertise starting from the early 1990s to late 2019, when North Korea ceased all negotiations with the United States. During that time, the conditions for productive negotiation changed dramatically – indeed, the conditions for the 1994 U.S.-North Korea Agreed Framework negotiations were much more favorable than during the Six-Party Talks of the mid-2000s or the Season of Summits during 2018-2019. For the “Negotiating with North Korea: Key Lessons Learned from Negotiators’ Genesis Period” project, a spotlight was placed on former senior negotiators’ early-stage experience preparing for and engaging in negotiations with the North Koreans. In doing so, tacit knowledge was captured to serve as a resource for future negotiators to inform and accelerate their own genesis period.

Stephen Walt argues that because no one knows what Putin might do, NATO's European members should increase their defense capabilities and correct any obvious vulnerabilities. At the same time, however, the United States and its NATO allies should acknowledge Russia's legitimate security concerns and consider what they can do to allay them.

Stephen Walt writes that those who favor foreign policy restraint believe the United States should trade and invest in other countries, encourage other states to do the same, and be open to managed immigration instead of building walls in a fit of xenophobia.

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

Stephen Walt argues that bringing Ukraine into NATO now is a bad idea that will prolong the war and leave Kyiv in an even worse position over time.

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

Matthew Evangelista examines the precedents and possibilities for postwar European security in an interview with International Security Executive Editor Jacqueline L. Hazelton.

Stephen Walt elaborates on the multiple obstacles that Europe faces on the way to military autonomy.

In this Q&A, Joseph S. Nye talks about his advice for the interim and future president of Harvard in the wake of Claudine Gay's resignation, which countries should be highest on our radar to prevent the threat of nuclear war, what role the U.S. should play in the Russia-Ukraine war, the significance of U.S. alliances in the Middle East, and more.
