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.

Power transitions affect a state’s ability to exercise economic statecraft. As a dominating and a rising power approach parity, they face structural incentives to decouple their economies. This decoupling affects business-state relations: high-value businesses within the dominant power tend to oppose their state’s economic statecraft because of its costs to them, whereas low-value businesses within the rising power tend to cooperate because they gain from it. 

When states use moral language in a dispute, they reduce the possibility of compromise. The possibility of military escalation, meanwhile, rises in response to moral language when states’ domestic audiences accuse their governments of hypocrisy for their willingness to compromise. The Falkland Islands/Islas Malvinas case explores the theory.

Atonement is an apology and reparations payments from one state to another for mass atrocities and other human rights abuses. The only case of atonement so far is that of West Germany and Israel in 1952. The West German decision to atone for the Holocaust was neither a moral choice nor the result of U.S. pressure. Instead, both countries saw atonement as politically expedient.

Kelly Greenhill argues that by exploiting political divisions that exist within targeted states, the threatened or actual deployment of engineered flows of migrants has long been a distressingly effective policy instrument, and it is unlikely to go away anytime soon. Unless policymakers begin to confront the forces that enable weaponized migration, the favored policy responses seem destined to increase, rather than curtail, its use.

Wedge strategy theory explains how states use strategic arms control to divide adversaries by affecting their trust, threat perceptions, and beliefs about a commitment’s trade-offs. Examining three landmark arms control negotiations shows how the wedge motive was a key component to these negotiations.
