A lot of what needs to be done here will have to be done quietly, without any discussion, using sources and methods that are available to our intelligence agencies, if we're going to be successful. That's the world we operate in, and so it's going to be vital for us to use any means at our disposal, basically, to achieve our objective."

- Vice President Dick Cheney, just five days after the 9/11 attacks.
