On this episode Mark talks with Alex Cooley and Dan Nexon, authors of ‘Exit from Hegemony: The Unraveling of the American Global Order.’ Scholars and pundits have been predicting the US’s decline as the singular world power since at least the 1970s. Now, with President Trump’s isolationist, nativist politics, many are saying this decline has finally arrived. Cooley and Nexon agree that the US’s exit from hegemony has begun — but as they explain, it started long before Trump’s inauguration.
