Calder Walton recounts how Russia and China are using their intelligence agencies to reverse the outcome of the Cold War

From July 11-12, 2023, NATO leaders gathered in Vilnius, Lithuania for one of the most significant NATO summits in history. This timely brief by Eric Rosenbach, Grace Jones, and Olivia Leiwant serves as a background piece on Ukraine’s history with NATO, potential future pathways for accession, and the operational impact Ukraine’s NATO membership could have on the alliance. 

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.

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.

The following is an event write-up about the recent Project on Europe and the Transatlantic Relationship (PETR) seminar on “France’s Global Role in a Changing World Order” co-moderated by Natalie Colbert, Executive Director of the Belfer Center, and Svenja Kirsch, Fellow with PETR, on April 19, 2023.

Joseph Nye considers U.S. options for risk reductions as nuclear threats escalate and China-Taiwan tensions rise.

Stephen Walt outlines how Washington and Beijing could stop the war in Ukraine.

Most public discussion this winter reflects a conviction that Ukraine must — and can — win a decisive victory. But what constitutes a win against a country such as Russia? As we consider the road ahead, we cannot escape the brute fact that Putin commands an arsenal of roughly 6,000 nuclear weapons that could kill us all.

Stephen Walt explains why Putin understood that Ukraine's fate was more important to Russia than it was to the West.

Stephen Walt argues that states that can attract and retain allies are more likely to succeed than those whose actions cause others to join forces against them.
