Daniel Keller: The petrodollar is why America can keep printing money, forever. And the rest of the demand for dollars around the world is so high because all oil business is done in dollars for other reasons, etc. I think that, yeah, that's what World War III is going to be fought over—the dominance of the dollar. Basically, the whole petrodollar system, and that is what is very much under pressure right now. And I don't know how directly linked that is to Corona, or how opportunistic this is to fit into that. But that's what's happening somewhat, at least.
