TSMC fabs have bombs build in to destroy everything if PROC invades I've read.

That's a bit hyperbolic don't you think? Sure, they're the only game in town when it comes to the leading edge nodes (eg. 3nm), but there's plenty of options at 14 nm and above. That corresponds to AMD zen (released in 2017) and Intel skylake (released in 2015). They're significantly worse than the latest and greatest CPUs today, but they're still in use today. I'd hardly call that as "going back to the stone age".

I also have a bridge I can sell you. And trust me: you've never seen one like this, at rates like I'm offering! Buy now!

You read bullshit.

No, you'll just have to learn how to write software again.

How would China do that exactly? None of their bombers have sufficient range.

They have intercontinental ballistic missiles. If needed, they can be retrofitted with non-nuclear payload.

The Chinese aren't stupid enough to do that. Any launch of ICBMs at a NATO country would be interpreted as a possible nuclear attack and draw an immediate US counterforce strike.

China launching any kind of missile at ASML is WW3
