After two decades, US forces have fully withdrawn from Iraq, leaving behind a nation grappling with its own security and a regional landscape ripe for new power struggles. While many Iraqis celebrated the departure, the vacuum created raises urgent questions about stability and the resurgence of familiar threats.

On September 30, 2026, the last contingent of U.S. military forces officially departed Iraq, marking the end of a two-decade-long intervention that began with the 2003 invasion.
