I agree. That's what should happen. Brazil have gone down this road and developed much more independent digital services. I'm not sure what analogue services remain.
The problem is Europeans haven't got alternatives. It is easier to find Indian IT alternative services than European ones.
The US could literally switch your phone off, stop mapping services, shutdown email systems, cloud storage, switch off business finance software, sales platforms, even specialist software such as video editing, defense systems or social media etc etc.
