Here's Dubya lying about something that's obviously false:

The larger point is, and the fundamental question is, did Saddam Hussein have a weapons program? And the answer is, absolutely. And we gave him a chance to allow the inspectors in, and he wouldn't let them in. And, therefore, after a reasonable request, we decided to remove him from power, along with other nations, so as to make sure he was not a threat to the United States and our friends and allies in the region. I firmly believe the decisions we made will make America more secure and the world more peaceful.

Note that this speech was long after the invasion. And Dubya's repeated this same claim a couple of times since.

Dubya's a lying sack'o'sh*te.... It's not even second-nature to him; it's instinctual.

Cheers,
