Baghdad fell on April 9, 2003, Hussein and his regime were brought down, we declared "Mission Accomplished" and celebrated victory . . . and chaos erupted. We did not assert control and authority over the country, especially Baghdad. We did not bring with us the capacity to impose our will. We did not take charge. And Iraq did not in a few weeks magically transform itself into a stable nation with democratic leaders. Instead a raging insurgency engulfed the country.
