If the US can maintain even just 5-10% of production volume, that's a huge win IMO. It means the US has a foundation of knowledge, equipment, and supply chains to expand on in the event of an emergency.

Taiwan is in a precarious position, which is a huge liability for "western" powers. And a liability for us is effectively also a liability for Taiwan, considering we are their protectorate. North America and western Europe are comparatively safe.
