I agree. Our intelligence also dropped the ball with respect to Libya's weapons programs. They were far more advanced than we expected. This intelligence failure took years to manifest and a war to expose it. It's going to take years to get our abilities to where they should be. But you're right, it's up to Bush to fix it.
From the "between the lines" reading I've done, it appears that Libya's nuclear program was actually where Hussein's nuclear program was being conducted - and for that reason the "Libya" program was more advanced, and the "Iraq" program was not as prominent.
