Trust me, BEFORE this happens, the dependent countries such as China, Korea, USA, Australia, Germany, France (okay, maybe not France), UK, etc, etc, would simply take control over these entities that are controlling the market. When it gets to a point to where leaders of a country have to decide if their country is going to become a third world nation because of the greed of others, drastic measures will be taken. I guess then the powers can come out and state that this is a war for oil! As long as oil is a fair market price there is no problem....but if a barrel of oil suddenly becomes $250 a barrel, you will see some "hostile takeovers" if you know what I mean. We cannot survive as a nation if you take a trillion dollars out of our economy a year and hand it over to OPEC, Exxon Mobil, Shell, Conoco Phillips, and all the others who post billions of dollars for their quarterly profits.
We could by a lot of cruise missiles for a trillion dollars!
