The mighty US military. lol
I think it's just a matter of time before whole world goes digital.
When every nation has their own block chain based currency and settlements between nations happen on a metablockchain and it's federated like SMTP (email) where I can send email from Yahoo to your Yandex email and Yandex can send to protonmail or Gmail etc there is no more need for one global reserve currency....
Petrodollar was really the US holding world's oil hostage ("protection" of OPEC) in exchange for the mafia hegemon tax/usurp after Fort Knox turned up empty of gold bars
Amerikkka plan is to use it's sanction power and chokehold of semiconductors as the new OPEC in the digital age and it's US military for coups to back it up in force...
For China and mankind's sake it better not work
In this regard China's semiconductor independence has a lot more riding on it than just Chinese tech Ascension. In this regard Huawei may be the savior of all humankind... It's not the hero the world deserves but it's the hero the world needs
