Is is all about the oil? But a different question arises now that war with Iraq is all but inevitable: What if there is no oil? The Pentagon should be very worried about what Saddam might do to his oil fields. Remember that when Iraqi troops were forced to leave Kuwait in 1991, they blew up 700 oil wells as they retreated. What an environmental catastrophe! And what an expense to clean up the toxic smoke reported as $20 billion by three American companies. The Pentagon is aware that the cost of clean-up may be more than double that figure taking into consideration that the Iraqi wells by contrast are larger than the Kuwaiti wells, more widely scattered and are not near the Persian Gulf which was an abundant source of water to quell the Kuwaiti fires.
