Nice informative post. I have read & heard about these facts else where as well. I believe you are correct.
It's all about selling oil in "PetroDollars". The western banksters want to control the sale of oil in the world so if you don't use USA$$ they will send in the military and destroy your country. Just consider Iraq, Afghanistan, Venezuela and of course Libya.
This is partly the reason the central bankers and supporters are trashing blockchain tech in the main stream media so much. It removes their domination over the people.
The best book I've read on how we have arrived at this mess is this:
Jane gives a detailed history of the Koch Bros, Mercers, Olins & more on how they've spent billions to impose the totalitarian state they want to control.
Thanks for the post.
