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.

Jay Mens asks: Why won't the U.S. admit that Iran's proxies, which include Hamas, are acting in concert?

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.

Do armed drone programs decrease or increase terrorism? Existing studies on this question produce conflicting arguments and evidence. Drone optimists contend that armed drones reduce a country's vulnerability to terrorism, while pessimists claim that this military technology provokes higher levels of terrorism. Prior research focuses almost exclusively on one particular context: the short-term effect of the US drone program in Pakistan. However, armed drones have proliferated rapidly over the last decade and eighteen countries now possess this technology. The authors expand the scope of prior studies by leveraging new data to assess how obtaining armed drones and conducting drone strikes changed the degree to which all drone possessors experienced terrorism between 2001 and 2019.

A new theory of war duration suggests that strategic narratives explain why the U.S. war in Afghanistan endured and ended. A robust anti-terrorism narrative generated audience costs for presidential inaction. As the narrative weakened, these costs declined, and the war ended.

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.
