The US claim on TSMC, are based on it using ASML (Dutch) equipment which has patent licenses from US. I was just answering the puzzling US colonial power roots. There may come a point of challenging the colonial patent power, while still attempting to pay for the patent, or China’s “delete America” program may get more allies or rebellion from the colonies.

China/BRICS is a much bigger market than US, and economics means figuring out a way to earn from all sides is motivated. US promises to isolate itself even more under Trump, and there is a limit to how much it will be respected.
