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. 

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.

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

During war, states trade two types of products with their enemies. To maximize revenues, states continue to trade products that are essential to the domestic economy or that their adversary takes a long time to convert into militarily capabilities.

The United States has employed targeted sanctions—economic and travel restrictions imposed directly on natural and legal persons—in a wide range of policy areas in the past two decades.  A substantial literature has considered the compatibility with international human rights law of the targeted sanctions practices of other actors, particularly the UN Security Council and the European Union. But relatively few scholars have examined U.S. targeted sanctions practices from that perspective. This essay argues that in principle, current U.S. designation practices can be reconciled with international standards.
