If you�re looking for a preview of what Colbert�s upcoming interview with O�Reilly might look like then this video may help. On Tuesday�s show, Colbert had on Dinesh D’Souza to promote his book, The Enemy At Home: The Cultural Left and Its Responsibility for 9/11. As you can probably gather from the title, the book scapegoats liberals for just about every disaster in our nation�s history using selective information and twisted logic.

In the beginning of his tirade, D’Souza gives an oversimplification of Iran�s history (without mentioning Mossadegh), and tries to establish a link between Iran and al-Qaeda. Linking al-Qaeda to the country you want to invade seems to be a neocon favorite. Luckily, Colbert was there to monopolize on every logical fallacy the man made. The more D’Souza talked, the more he dug himself a deeper whole. By the end of the interview, Colbert had ridiculed him to nothing more than a laughable caricature. If only our politicians were half as fearless as our comedians.

Colbert’s money quote: “So what other cultural editing notes should we take from the terrorists?”
