CPU and GPU logic, that's it. Possibly Semiconductor fabrication (Intel 14A is actually shaping up well after a few years of being well behind TSMC) but they rely heavily on ASML.

Couldn't think of a single other thing USA actually makes the best of.

Medicine? Nope.

Food - c'mon lets be serious...

Cars - again lets be serious...

Tools - nope.

Weapons - nope. US now buys Euro designs for guns then makes them so poorly they don't work.

Satellites - nope.

Entertainment - nope.

They can't even get bread and circuses right.
