My fellow citizens, at this hour, American and coalition forces are in the early stages of military operations to disarm Iraq, to free its people, and to defend the world from grave danger.

Near the end of the speech he said:

Now that conflict has come, the only way to limit its duration is to apply decisive force. And I assure you, this will not be a campaign of half measures, and we will accept no outcome but victory.

Six short weeks later he said the following:

...officers and sailors of the USS Abraham Lincoln, my fellow Americans: Major combat operations in Iraq have ended. In the battle of Iraq, the United States and our allies have prevailed. And now our coalition is engaged in securing and reconstructing that country.

Six long years later, we are still in Iraq, although there never was anything to disarm there and the country had nothing to do with 9/11.
