From “Without a Doubt,” an October 2004 New York Times Magazine article about the Bush administration written by Ron Suskind:

In the summer of 2002, after I had written an article in Esquire that the White House didn’t like about Bush’s former communications director, Karen Hughes, I had a meeting with a senior adviser to Bush. He expressed the White House’s displeasure, and then he told me something that at the time I didn’t fully comprehend — but which I now believe gets to the very heart of the Bush presidency.

The aide said that guys like me were ”in what we call the reality-based community,” which he defined as people who ”believe that solutions emerge from your judicious study of discernible reality.” I nodded and murmured something about enlightenment principles and empiricism. He cut me off. ”That’s not the way the world really works anymore,” he continued. ”We’re an empire now, and when we act, we create our own reality. And while you’re studying that reality — judiciously, as you will — we’ll act again, creating other new realities, which you can study too, and that’s how things will sort out. We’re history’s actors . . . and you, all of you, will be left to just study what we do.”

It is interesting that this statement was made just a few months after the secret Downing Street memos and minutes were written.

The documents provide evidence that the Bush Administration, in collusion with the British, conspired to incite public support for forcible regime change in Iraq by creating a reality in which Saddam Hussein represented a dire and direct threat to the United States.

The smoking gun would be a mushroom cloud.
