Taiwan and it's semiconductor businesses produce revenue that could pay back for a war.
I don't see that as being a reality - semi-conductor production is hugely complex and relies on massive chains of experience, design, development and materials. It would take more than capturing the facilities intact, even with key staff to do much useful.
The US would then massively ramp up facilities in Germany and the US owned, or formerly owned by the likes of TSMC, IBM and TI and a lot of stuff would become hideously expensive to pay that back.
