Newsweek has an excellent interview with British MP and resigned cabinet member Robin Cook
Sample:
Q: Isn’t it possible that Saddam Hussein ordered their destruction, as U.S. Defense Secretary Donald Rumsfeld has suggested?
A: No. I don’t think it’s even remotely possible. I just cannot follow the Rumsfeld logic; that watching CNN and seeing the American build-up Saddam said to his generals, “It’s obvious that the U.S. is going to invade; we had better destroy our biggest weapons, so that when I am toppled there might be some very difficult questions for Donald Rumsfeld to answer.”
