Why do you think Saddam took the enormous risk of occupying Kuweit? It is quite likely that the Iraqi government and at leat the experts in their oil ministry had a fairly accurate picture.

But there is, of course, one oil company that is really interested in Iraqi oil - the national Iranian oil company. Thyey already agreed to build a pipeline from Southern Iraqi fields to Iran. They have functioning export terminals for the Iraqi oil. They have troops to protect the structures - the Iranian backed Shiite militias -  and a friendly government to make deals with - the Iranian backed Shiite dominated government in Baghdad and soon in Basra, too. They have their men in the Iraqi oil ministry now. They let Chalabi and friends to tell fairy tales about the huge oil riches in Iraq before the war. Iran fought eight years for the oil fields in Southern Iraq. Now they can access them.

The Iranians have no capacity to make nuclear weapons, but they have a capacity get the oil in Iraq. See what the Gulf states are doing: trying to rob each others oil. This is desperate and tells a lot about the real situation of the ME oil.
