Matthew Simmons most recent 26 page booklet on the Saudi Arabia Reserves is worth reading if you want more evidence.
Peak oil is already here
Now that everyone agrees oil production is in decline, what’s next?
Hot or cold on any scale, the War of Resources is now the overriding economic, military, and political priority in the capitals of all countries involved, major and minor. It is from now on safe to assume that major combatants have switched over their economies, foreign policies, and militaries to a total war footing as all-encompassing as major combatants did during World War II. It is equally safe to assume all minor players are busily maneuvering and negotiating their positions in between the major combatants, looking for their safest harbours in the coming storms. All political and economic news coming from all players big and small from now on must be interpreted through the lens of the War of Resources. It is “game on” as of this moment.
There are six powerful nations that, with the passing of peak oil and the dawning of the War of Resources, now comprise the six major powers in that war: they are the United States, the European Union, Russia, China, Japan, and India. These six may from time to time form temporary alliances among each other in all possible configurations, as their own calculations dictate. But they are each in the game for themselves, and hostilities in any configuration are also possible—a point that cannot be emphasized enough.

There are as well six major private oil companies powerful enough to be considered instrumental in the political, economic, and military decisions made in any and all of these capitals as the War of Resources unfolds. These companies are BP-Amoco, RoyalDutch/Shell, ExxonMobil, ChevronTexaco, TotalFinaElf and ConocoPhillips. These companies will play the role of regulating the relative heat of this war in each of its big and small battlefields with an eye toward maximizing their profits.
