I forgot to add that the recent moves by China, Russia, Venezuela, and more to abandon the dollar / petrodollar will most likely evoke a certain response from the USSA. That response will be very similar to the responses to the attempts by Saddam, Ghaddafi, and Assad to abandon the dollar.
But there's not much that the US can do anymore to stop the de-dollarization trend. The dollar is doomed, and the empire is doomed. Let's hope the many innocent people survive the collapse.
