From veteran FRONTLINE filmmaker and chronicler of U.S. politics Michael Kirk and his team, this documentary traces the U.S. response to the September 11, 2001 terrorist attacks and the devastating consequences that unfolded across four presidencies. Drawing on both new interviews and those from the dozens of documentaries Kirk and his award-winning team made in the years after 9/11, this two-hour special offers an epic re-examination of the decisions that changed the world and transformed America. From the wars in Afghanistan and Iraq to the January 6 insurrection, America After 9/11 exposes the legacy of September 11 — and the ongoing challenge it poses for the president and the country.
