I have a question. How do we know that everything electric would be wiped out by a nuke? Have we done it in testing?

Really that’s more of an airburst phenomenon.

We *know* that semiconductors, unless properly shielded get wiped by an EMP. Period. It’s a big vulnerability for modern tech, because vacuum tubes are the only kind of electronics that can take an EMP unshielded and keep working.

Handheld consumer electronics do not have EMP protection. We used that to our advantage in Kosovo starting with the cold EMP bombs (non-nuclear EMP generation) first deployed there to zap cell phones and computers in areas of operation.

Short answer, yes. The US have conducted tests.
