It's an internet meme that some goof at US Army War College picked up on and wrote a paper suggesting TW should blow up their own fabs to deter PRC invasion. Which is dummy take since for PRC, TW is a political problem and US can always strangle fab operations via supply chain sanctions. TW media saw this as serious traction and pushed some articles basically saying "leave TSMC alone". TW, at least TW leadership won't blow up TSMC for the simple reason that it'll destroy US advanced economy, and if they ever want a safe ride off the island to retire in US, it would be in everyones interest the fabs stay untouched.
