Bush doing this for the oil? I don't think so. That sounds very sound and logic, but I don't think that is the reason. That would be like saying he is doing this to deflect attention from the fact our unemployment is sky high, our economy sucks and we STILL have not found a fucking cave hermit in Afganistan.
I honestly do not think the war will last very long. It is natural thinking to reason that Saddam has taken remedy precautions against all his mistakes and losses from the first Gulf War. However, you have to remember that the Iraqi soldiers remember all too well what happened then and I expect them to be surrendering by the hundreds of thousands after the first shot. No one wants to play for a losing team. They have nothing to gain but death either way you look at it. Might as well cast your dice with the victor and hope for better treatment.
The main concern is that from the first Gulf War, Saddam made mortal enemies of the Kurds and with Isreal. Rather than fight us directly, he launched missile attacks on Isreal and then out of anger gassed all those Kurds after the war. I think the big problem is that when the war is under way, Isreal and Kurds are going to be frothing at the mouth and crazed with bloodlust and we could very well see an entire massacre of Saddam and his regime.
Not that I would shed a tear.
