Presumably a bunch of Europeans would lose their jobs if the Americans stop buying cars and machine tools and whatnot from Europe.
On top of that they're luxury goods, their bought for their prestige. Barely anyone uses AWS for such reasons. Good luck convincing the wealthy in the US that some new US brand is a good replacement for their Louis Vuitton bags, Moët champagne and Bulgari watches.
The US has lots of ultra-luxury services, but very little such manufacturing.
Depends how far the culture war goes.
