What are the economic and geopolitical effects of President Trump's imposition of tariffs on America's trading friends and foes? In an episode devoted solely to viewers' questions, Hoover senior fellows Sir Niall Ferguson, John Cochrane, and Lt. Gen. H.R. McMaster delve into the certain volatility (and uncertain logic) of Trump's tariff maneuvers, what the future holds for the European Union, institutional decline within the U.S., plus what if any parallels between historical periods past and present (do all roads lead to Rome or Richard Nixon?). Also discussed: the uniqueness of a hybrid American republic/empire, "sleeper" nations that might emerge as powerhouses by 2050, and recommended biographies for secondary-school readers. Finally, as this month marks GoodFellows' fifth anniversary, the three fellows reflect on what they've learned over the course of gathering online and in-person for 150-plus shows. Recorded on April 10, 2025. ABOUT THE SERIES GoodFellows, a Hoover Institution broadcast, features senior fellows John Cochrane, Niall Ferguson, and H.R. McMaster discussing the social, economic, and geostrategic ramifications of this changed world.
