EMP only affects things that are not shielded and it takes a lot of energy to ruin micro circuits. The energy falls of proportional to r². For the most part your computer, if on, may act funny and all you you would have to do is reboot it. If your car was not running probably need to do nothing. The car hood is not a perfect but a pretty good EMP shield. Things that operate old school like small engines that have a magneto ignition would be totally unaffected.

Wouldn’t there have to be many EMP bursts to cripple the country? I keep hearing how one weapon strategically detonated could cripple all of the nation’s electricity. That is a hell of a lot of area. I may be naïve, but that just doesn’t seem possible.

“The energy falls of proportional to r2”

Not in the near-field, which is why HEMP does not decay by inverse square.

Non-nuclear EMP does though.

Pry is mostly a screwball, but HEMP is not a hoax. We do not know how bad an Event would impact us. We know enough to say it will not be good.
