The US is fighting wars with everyone on everything at the same time. They don't have the resources to do anything about it. Every country will develop their own independent payment networks.

China was right to block US tech companies to promote their own, most large and capable countries will do the same over time.

I wouldn't cite China as the example. If they had their way, every country would have its own firewall just like them, giving them significant control over information flow to their citizens. It works very well. That's why they have been pushing "internet sovereignty" for years.
