American policy toward the Middle East has always been determined by the politics of oil and the politics of oil are determined by the oil companies.
It would be difficult to find many who would argue that the invasion of Iraq was premised, not on seizing Iraq's oil, but rather to eliminate the threat of nuclear weapons held by Saddam Hussein.
Six of the world's 10 biggest companies are oil companies. These companies operate primarily in the Middle East, but their search for oil and profit has taken them throughout the world. Seventy percent of the fuel used by power companies to generate electricity in this country is fossil fuel. That is; oil, coal and gas.
The oil and utility companies hold enormous political power in this country as well. They can by providing, or withholding, funds to ambitious politicians decide the outcome of elections.
