This episode explores the origins and early years of the War in Afghanistan, beginning after 9/11 when the U.S. invaded to topple the Taliban and destroy Al-Qaeda. Initial victories gave way to a long insurgency, complicated by Afghanistan’s geography, tribal politics, and the Taliban’s resilience.

Efforts at nation-building faced corruption and mistrust, while the U.S. shift of focus to Iraq weakened the mission. By the late 2000s, the war had become prolonged, costly, and uncertain—marking the beginning of America’s longest war.
