Is it safe to assume that George Tenet will write a book in the next few months that points out all the mistakes the Bush administration has made in the last four years?

I've already written the "official" response to the book:

Fox News Exclusive:

George Tenet is just a disillusioned former employee on the brink of insanity. John Ashcroft is looking forward to opening an investigation as to the use of classified documents in the book. Tenet wasn't really in the loop. President Bush may have spoken to him once at a luncheon, but that's the only encounter they ever had.
It is also believed that Tenet is now working for the John Kerry campaign.

Right.

As an aside, The Onion daily calendar headline for June 3rd reads: "Casual One-Nighter Gives Strom Thurmond Change of Heart On Homosexuality Issue".

Awesome
