That the limited information we could get out of Iraq would lead a reasonable person or intelligence agency to conclude that Saddam could be hiding something serious.
This conclusion was drawn by one heck of a lot more people than just Bush. The Clinton administration firmly believed the same thing, as well as intelligence agencies in other countries, yet somehow this is glossed over as irrelevant.
And by all means, let's have the CIA publish all the clandestine information they receive. Maybe we can include the names and addresses of undercover agents. Used to be a favorite sport of the Left back during the Cold War.
