Even if it were bad for Taiwan, geopolitics is about more than Taiwan. But I’m not sure this is bad for Taiwan: today, China can wipe out TSMC overnight. With these fabs there will be Taiwanese revenue streams coming from mainland US, which streams can support Taiwan government and military. Walk me through why it’s bad for Taiwan to be more economically diversified?
Well for one the US won't be so inclined to defend TW so much. Sure, there will be posturing, maybe even a proxy war like in Ukraine, but generally speaking the US will not be sending troops anymore, now that the golden goose has nested on its shores.
The US had no strategic interest in Ukraine yet we’ve all seen the reaction. The US will gladly defend Taiwan and create the hill for the CCP to die upon.
