The U.S. couldn't play a military role in different areas like Iraq and Afghanistan without huge quantities of oil. So a shortage or disruption in oil would not only damage the U.S. economy it would undercut American military supremacy.

Oil is also essential for military operations. No other substance, no other raw material, is so vital for the prosecution of warfare, than petroleum. And the United States being the world's only global power, is totally dependent on petroleum.

Slowly but surely, the U.S. military is being converted into a global oil-protection service.

The global supply of oil is going to decline because we've used up a good deal of the easy-to-get oil. We're going to reach a point in the not-too-distant future when it is impossible to keep increasing the daily supply.

Oil is essential for a modern, industrial society. It's unique, first of all, because it's the primary source, at 40 percent, of the world's entire supply of energy, and it's irreplaceable in the transportation field it provides 98 percent of world transportation energy.

A new chapter in the history of international politics has begun, one in which the pursuit and control of energy resources would be the central dynamic of world affairs, and governments.
