yeah, but ... does the IP for TSMC reside in some easily transferred tangibles? wouldn't the DOD really need to transfer the whole community of engineers and ecosystem of suppliers?
Engineers in Taiwan don't make that much money. Just saying you'll pay them standard US engineer salaries and add instant green cards for their families as part of the acquisition and you'd probably get most of them to move.
TSMC although is a pretty foundational company of Taiwan. It would be like the US buying samsung and then moving everyone to the USA. Taiwan might stop you.
