Nobody can control TSMC except TSMC lol. The equipment is incredibly delicate and incredibly precise. If TSMC decided to wake up one day and destroy their entire business, they could be done before lunch. Anyway, TSMC is only really relevant because government subsidies allowed it to outlast American and Korean fabs. Whereas GloFo had to pull out and Intel burned almost a decade on delays, TSMC was able to make progress. That's not a long-term objective worth invading over.

Moreover, note how I talked about integration. Recent calls for independence have mostly been driven by DPP politicking. Oddly enough, the DPP is funded rather heavily by US interests, which I'm sure is a complete coincidence.

An invasion isn't happening and pretending that one is is harmful to stability in the region.
