"Admittedly, I am not well versed on EMP attack consequences, but while I understand the theory, I still don’t see how a single attack could disrupt every square mile of the U.S. It would seem that many such devices would have to be detonated."

I agree. This threat is really just a theory. The tests that I'm aware of have shown minimal effect from EMP. Nukes have already been detonated in space and we are still functioning just fine. I seriously doubt even the US could produce an EMP that would wipe out thousands of square miles of electronics.

We can always go old school.

Starfish Prime caused an electromagnetic pulse (EMP), which was far larger than expected, so much larger that it drove much of the instrumentation off scale, causing great difficulty in getting accurate measurements. The Starfish Prime electromagnetic pulse also made those effects known to the public by causing electrical damage in Hawaii, about 1,445 kilometres (898 mi) away from the detonation point, knocking out about 300 streetlights,[6] setting off numerous burglar alarms and damaging a telephone company microwave link. The EMP damage to the microwave link shut down telephone calls from Kauai to the other Hawaiian islands.

The explosion was 900 miles from Hawaii and that was 50 years ago when electronic were thick wires and vacuum tubes. Today we have tiny little wires and micro chips. I'd say there is reason to be concerned about an EMP attack.

The EMP answer resides

in the power & conduction contrasts

between A) electrical insulator (tested) and B) electronics interface (untested).

Perhaps you can explain those to us.

Otherwise, I can explain, WE ARE SCREWED!

EMP answer in layman’s terms.

Electronic: Create static charge voltage, by dragging your feet across the living room carpet, while handling your internal computer circuit boards. Damage is easy, even without EMP.

Electrical: Hold an incandescent light bulb in your hand. Keep shuffling & rubbing the carpet. Make the light bulb turn on or burn out.

EMP can effect the bulb from far away. You cannot.
EMP can far easier burn out electronics, due to micro gaps and semi conduction. Nuclear power plants are sitting ducks.
