From the end of the Cold War, US foreign policy evolved from a focus solely on the nation’s vital interests, to saving people from ethnic, tribal and nationalistic slaughter—with no direct US benefit—as in Kosovo, Somalia and Haiti. Yet, a coincident genocide in Rwanda, where 800,000 men, women and children were murdered, elicited no reaction. First, how and why did this (inconsistently applied) transformation of focus come about? Second, rapidly rising authoritarianism in countries as disparate as Turkey, the Philippines, Venezuela, Hungary, Russia and China poses a new question: Will the post-1945 US-created and US-led liberal world order survive, or succumb to dictatorship and world disorder? And third, policies outlined during the 2016 presidential campaign, and now under review by the administration, raise an additional question: What would happen if the US abdicates leadership of that uniquely successful global order? The course will examine and debate these world-changing questions.
