I’d rather prepare for life with China in total control of Taiwan than try and defend Taiwan from China. I believe they will take Taiwan without bloodshed, anyway. Which is why it is critical to build up the US advanced manufacturing base. It will take a long time and cost a lot of money.

I believe the US government agrees with you, which is why they are investing in domestic alternatives to TSMC (including encouraging TSMC to build a plant in the US).
