Charles Kupchan, one of America’s leading foreign policy scholars and a former White House official, argues that Donald Trump’s “America First” marks another swing in the long pendulum of US foreign policy, but warns that today’s challenge extends beyond foreign affairs to the resilience of liberal democracy itself. In his interview with Formiche/Decode39, Kupchan says the forces that fueled MAGA could soon strengthen similar movements across Europe, raising new questions about the future of the transatlantic alliance and the West’s democratic cohesion.
