In the aftermath of the U.S. intervention in Venezuela, we explore how rising political divides are leading to bigger swings in America's foreign policy — and what that means for our future in the liberal international order.In her book Polarization and International Politics: How Extreme Partisanship Threatens Global Security, Rachel Myrick argues that polarization reshapes the nature of constraints on democratic leaders, which in turn erodes the advantages democracies have in foreign affairs. We discuss how the pendulum swing from one administration to another leads to instability in foreign affairs. As a result, Myrick says the United States loses both reliability as an ally and credibility as an adversary. Myrick also questions the longstanding thinking that having a common enemy to focus on is enough to overcome polarization, as it was during the Cold War.Myrick is the Douglas & Ellen Lowey Associate Professor of Political Science at Duke University. Her research explores how partisan polarization affects foreign policymaking in democracies, with an emphasis on U.S. national security policy.  Hosted by Simplecast, an AdsWizz company.
