"Sources & Methods" is NPR's weekly deep-dive into national security and foreign policy, hosted by Mary Louise Kelly alongside veteran NPR correspondents. Airing every Thursday, the show unpacks the biggest stories shaping America's role in the world—from cyberwarfare and missile shortages to shifting alliances in Iran, Ukraine, and beyond. Episodes blend analytical roundtable discussions among Pentagon, State Department, and intelligence beat reporters with in-depth interviews featuring military officials, diplomats, and authors covering global conflict zones. The tone is authoritative yet accessible, translating complex geopolitical developments into clear implications for everyday Americans. Ideal for policy wonks, news junkies, and anyone seeking expert-level context on defense, diplomacy, and intelligence matters, the podcast distinguishes itself through NPR's signature journalistic rigor, insider access, and a consistent focus on how distant conflicts ripple back home. Recurring themes include cybersecurity threats, military strategy, and the evolving balance of global power.
