In my opinion, the leaders of OPEC nations are still nothing but petty thugs. But they are in control of the world.
Control of the world may be streaching things, but OPEC's control over a health percentage of the world's petroleum and the petro-dollars that come with it has for decades given them sway in international matters.
Does that put them at the same table as other world leaders? Yes, because they have the ability to malnipulate.
If nothing else, without oil would the banking world gradually be moving to Dubai?
