The 20th anniversary of the United States-led invasion of Iraq is on March 20, 2023. Codenamed "Operation Iraqi Freedom" by the George W Bush administration, the goal was to eliminate weapons of mass destruction, topple Saddam Hussein, and re-make Iraq into a democracy. Two decades later, US troops are still on Iraqi soil and that nation is ravaged by challenges, including a threat of civil war last August. Center scholars weigh in on the history that led to the US invasion, lessons learned on state-building, and provide commentary on Iraq's future.
