Everything changes in a single morning. In this episode, we revisit the shock, grief, and unity that followed the attacks of September 11, 2001—and the sweeping global response that reshaped U.S. policy for decades to come. From the hunt for al-Qaeda to the invasion of Afghanistan, from new security laws at home to complicated debates about liberty and fear, this is the story of a nation thrown into a new kind of conflict. It's urgent, emotional, and deeply defining—an inflection point where the 21st century truly begins.
