US alone is meaningless, powerless and insignificant and needs friends and peers more desperately than ever, containing less than 5% of the world population. Sure you can go North Korea style but why lose everything that was gained so hard.
The US has the world by the proverbial balls. It would take years before everyone can fully divest itself of US tech.
This is a foolishly dangerous assumption. America's premier digital exports are things that many other nations consider entirely unnecessary. The App Store? Illegal in parts of Europe. ChatGPT? Questionably valuable from the start. Facebook, X/Twitter, WhatsApp and iMessage are all NSA informants. We have examples of countries kicking FAANG out of their market, and these countries are perfectly successful in the long run.
You are very focused on the American lifestyle. I suspect you would be very surprised by how little Europe cares about American software businesses.
*whoosh*? Not sure, but that's either a videogame meme or some repurposed good ol' mid-20th Commie paranoia.

85% of the world's handguns though.
(Yes, I made that up. Wikipedia says it's only 46%).
(Serious question: How do you apply export sanctions to one bit of a single market? Is this just theatre?)
