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.

We have to be on guard that we don't spend so much time worrying about terrorism and guarding ourselves that we start to lose the essence of who we are as an open, freedom-loving people, welcoming to the rest of the world.
