This episode examines the strain on U.S.-NATO relations as the Pentagon pulls troops from Germany, contrasting Trump’s transactional view with NATO’s strategic purpose. Historian Heather Cox Richardson and expert Nikki Akani explain that the alliance is a collective security framework, not a pay-for-protection service. They discuss how shifting perceptions of defense spending and U.S. withdrawal threats could undermine global stability and prompt European allies to seek independent security arrangements.
