> most of those expensive high-end chips will just be shipped to Asia for assembly
I get the first part of your comment, but why wouldn't all the missing components be imported for assembly in the US? SMT lines in particular don't need that much cheap labour to operate. Even Brits can assemble PCBs!
Either you ship one component to Asia where it'll be combined with thousands of parts made by factories literally in the same city, or you're shipping all those thousands of parts over the US for assembly. Even with zero labor cost for assembly it's not hard to guess which option is cheaper and easier to manage.
