You are American ("We should just bomb...")?

A better idea is to give a US passport to every TSMC employee NOW (exempt them from having to hold a green card and live in USA for 5 years first). And change the law so that US citizens residing overseas with no US-sourced income are exempted from filing and paying taxes.

Other countries that wish to have leading edge commercial fabs, e.g. Germany or Netherlands, should compete with USA and try to get their passports to TSMC employees first. Tell them your country does not tax citizens on overseas income, and like Taiwan, has universal healthcare, high-speed rail, and gun control. Netherlands can also advertise that TSMC employees likely already have some Dutch friends at ASML.

Rumor is that Taiwan already has this handled. That there are rooms with explosives to scuttle the plants if the China lands troops on the island.

Removes the option of a painless transfer of power so that the US is still geopolitically interested in a independent Taiwan.
