Yes, I posted a vanity in Dec. called "Should we do Saudi Arabia first?" I asked Jim to pull it after it degenerated into a flamefest, but it's still a good question.
I think the powers that be have decided that with Iraq we will get two for the price of one - if we do SA it will make Saddam certain he's next, and create a window of opportunity for all-out WMD deployment if he has any-but if we do Saddam first, the Saudis will get the message, shape up, and we won't have to occupy them.
I'm not sure that's factual, but I think Bush and Rummy believe it, and they get to decide.
