From Against All Enemies:
Before lifting off again [in Air Force One on 9/11], Bush taped a statement to be broadcast only after he was airborne. “Make no mistake. The United States will hunt down and punish those responsible for these cowardly acts.” At this point, they hardly seemed cowardly.
Maher lost his TV show for saying the same thing. Say what you will about the suicide terrorists, they are not cowardly.
