I couldn't read further. The U.S. can make--has made--it's own chips. Taiwan can't make their cutting edge chips without U.S. and European technology. Research ASML for starters. China has no capabilities to "rebuild"? What do you mean by that. Whatever capabilities they've built they still have.

In short, advanced tech requires global integration--which includes China! If China invaded Taiwan it would kill its own economy. Just because Putin did that doesn't mean Xi will.
