I think it is the opposite. We were saying petrodollar exactly because the dollar was backed up by the Saudi Arabian oil. The deal with the Saudis was so that people had to use the dollar for their transactions. Without that, the dollar would not have been the global reserve currency and they would not have the ability to print as much they want because that would cause the currency to be inflatory without much value. Now that has gone, and their ability to project their power in other places is in decline, they need the oil of Venezuela which also is not far, to back the currency. Yet, since they kicked out Russia from swift2 and lost, half of the world is trading in other currencies and the trend is that will grow. They are in hurry, that is why they make panicked moves and show their true undemocratic and tyrrant colours
