White House Press Secretary Ari Fleischer, July 9, 2003, in a transcript not available from the White House itself:

But there's a bigger picture here, and this is what's fundamental -- the case for war against Iraq was based on the threat that Saddam Hussein posed because of his possession of weapons of mass destruction, chemical and biological, and his efforts to reconstitute a nuclear program. In 1991, everybody in the world underestimated how close he was to getting a nuclear weapon. The case for going to war against Saddam is as just today as it was the day the President gave that speech.

It remains true that many, many neocons believed and advanced reasons for invading Iraq beyond WMD. It also remains true that "the case for war against Iraq was based on the threat that Saddam Hussein posed because of his possession of weapons of mass destruction." Believing in other reasons does not change this.
