Less so that thought. TSMC is Chinese via it being Taiwanese. No disparagement of regional uniqueness or actual ownership, just its success is a success of the Chinese people (into which Taiwanese are included). China will not substantially harm TSMC when it is so successful at destroying American dominance in a key industry. Taiwan and China are very much aligned when it comes to TSMC. Maintaining a US native foundry might actually be a way to prevent war because one of the key triggers might be the moment where all major chip players totally depend on TSMC, which gives Chinese/Taiwanese massive leverage. Economically, might be a loss leader. But strategically, important, probably.
