The thing is that we had been allies for many decades. So the US and the EU are very entwined. You only mention one side, those chips are made using ASML machines from The Netherlands (with lenses from Germany), the latter two use an architecture licensed from a UK company (owned by a Japanese conglomerate). It was a very successful cooperation between two continents, but since the US wants to throw that under the bus, we have to become self-sufficient.

It will take time to untangle the mutual dependencies and become more independent. That said, ARM also designs full ARM64 cores (until recently Qualcomm cores were based on ARM cores, until the new cores based on the NUVIA acquisition) and they can be fabbed in Taiwan (TSMC) and South Korea (Samsung), and hopefully Europe in some years.

Besides that, it's true that if you are running Linux, you rely on US firmware and Intel/AMD chips, but assuming that Intel ME doesn't have a bad remote kill switch, you can continue to run on existing hardware.
