George W. Bush: “We're going to shake terrorism loose wherever it exists and bring those to justice who have hurt America.”

To you and the honored dead, our country is forever grateful.

We are heartbroken by the loss of life and the agony so many are feeling.

I have confidence in the promise of America because I know the character of our people.

The creativity, ingenuity, and resourcefulness of the American people is our country's greatest strength.
