S10 Ep27: Trump, Greenland, and an Alliance in Crisis with Shane Harris

Shane Harris joins Matt to discuss his latest reporting for The Atlantic on one of the most destabilizing ideas circulating inside the Trump administration: the U.S. acquisition of Greenland. Shane explains how an idea once dismissed as a punchline is now being treated by U.S. and European officials as a real contingency, and why Denmark and Greenland view it as an existential threat. They examine how the proposal took shape inside Trump’s orbit, why political and intelligence pressure campaigns may already be backfiring, and what unilateral action—by force or fiat—would mean for NATO and the future of the transatlantic alliance.
