saddam had at least one junked body of a 747 that was used to train on (hijacking) in the country. he knew about it, but chose not to stop it... that doesn't mean he knew and talked to all involved, but it was going on and saddam let it continue. Again, there is evidence that chemicals were being moved in water trucks not long before the invasion occurred. I would consider chemical weapons and such training as threats... whether they were big enough to merit an invasion is a different subject. But i would say planning assassination attempts on foreign leaders and having the money to back them would make them at least a minor threat
as far as the report coming out after the election... it'd be stupid of him to let it out before if its going to cite him as responsible. That may suck, but unfortunately he isn't the first or last to do something of that sort (N korea is waiting till after our elections to hold talks so that they can try to get a softer president to deal with)...
