Matthew Evangelista examines the precedents and possibilities for postwar European security.

Stephen Walt writes that the differences in foreign policy will be less significant than one may think. Consider how Trump and Biden would each likely deal with the three most important items on the current foreign-policy agenda: Ukraine, China, and the Middle East.

Stephen Walt argues that Henry Kissinger's concerns about the destabilizing impact of ideas made him hypersensitive to the smallest perturbations in strategically marginal countries and inclined him to overreact to them in ways that other realists opposed.

For Ukraine to maintain its defense and decisively thwart Russia’s invasion, it will take steadfast commitments from Western allies providing both state-of-the-art equipment and basic warfighting needs, local industry leaders and factory workers readying equipment for the frontlines and developing innovative technologies, and civilian volunteers tirelessly filling in the remaining gaps.

Stephen Walt analyzes the costs and benefits of forming alliances. When powerful and stable states face the same threats that the United States does, forming an alliance with them makes good sense. Adding weak and vulnerable members to an alliance may not strengthen it, and long-standing partnerships become less effective if some members let their own military capabilities languish. Another problem with the overzealous pursuit of new partners is the possibility that their agendas will be incompatible with those of the United States. 

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.

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.

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