National security, unlocked. Each Thursday, host Mary Louise Kelly and a team of NPR correspondents discuss the biggest national security news of the week. With decades of reporting from battlefields and the halls of power, they bring you inside the Pentagon, State Department, and intelligence community to help you understand America's shifting role in the world, and how events in faraway places matter here at home. Additional episodes feature interviews with power players from the NatSec world -- current and former military officials, intelligence experts, diplomatic leaders, and more.Email the show at sourcesandmethods@npr.org.
