We face an ever more dangerous geopolitical environment. In this Conversation, Princeton professor and AEI nonresident senior fellow Aaron Friedberg analyzes America’s foreign policy challenges and considers how a Harris or Trump administration might approach the threats we face. According to Friedberg, the cooperation among Russia, China, Iran, North Korea “has grown more and more sophisticated and complex” in recent times, making the challenges in the Middle East, Eastern Europe, and Southeast Asia more difficult to address—as well as more interrelated. Friedberg argues that the volatility in American domestic politics makes predicting the American approach to countering these threats increasingly uncertain. As he puts it, “If Trump comes back, the range of possible policies in each of these areas is just much wider than would have been typically the case in the past”—and a key question with Harris is "To what extent does she share [Biden’s] gut instinct regarding American leadership?"
