TSMC is building a huge fab here in America. It's a couple/few years out, but that would do a lot to alleviate this risk. And it could be rushed if it were prioritized as an American National Security Project.
The fab TSMC is building in America is such a small amount of their volume as to make almost no difference. And it won’t even be a leading node by the time it’s built.
No. I think the CCP wants Taiwan indifferent of it being an economic powerhouse, or a broken 3rd world island. Failure to integrate Taiwan has been a stain on the CCP system, and it's not a system that can afford any stains.
All I'm pointing out is should Taiwan be invaded, TSMC stands to be in a position to receive a significant infusion of government cash to bring that fab online ASAP. And once that FAB is completed the systemic risk of China to TSMC evaporates, and at that point I believe that TSMC goes to the moon.
