Martlet considering that OBL was a direct enemy to Saddams government (as were any Islamic terrorist groups) and the fact that the only known terrorist camp (well at least publicied lately) was in fact in the north-east, kurdish ruled part of the country, there was little proof to back up your statement.
If something, Saddams attacks on the kurds could have been seen as a campaign to get rid of the illegal terrorist camps in the northern territory.
Could have, even though that's not likely to be the case. He was a murdering bastard. But a threat to the US? Not likely.
No, this war had nothing to do with any perceivable threats to the US, it was GB2 finishing his daddy's job. He wanted to stabilise the situation in the middle east by imposing US power on the region --> effectively replacing the government of Iraq with a US puppet government. And make a few bucks in the process.
I wouldn't be surprised if soon people will find out that GWB's family has directly or indirectly large quantities of stock of the company that was secretely and solely awarded the reconstruction of the country. I smell another Watergate (or do you even care anymore.)
