I read the book 2 weeks ago.

I'm an Electrical Engineer.
I work in the defense industry. I've analysed some projects for some of their characteristics related to their EMP-resistance.

I don't expect any of my cars or my motorcycle to run afterwards (though they might - depends on many factors)


EMP is a very serious threat to the US though it is just one of many possibilities.
An EMP weapon is a very cost-effective way to attack the most electronically dependent nation that has ever existed.
An EMP weapon can be manufactured without using nuclear detonation to create the pulse though it would be shorter ranged.
But that just means a few more are needed.
For a nuclear warhead EMP all it really would take is 1 at high altitude.

Reading the book spurred me to put together a walk-home-from-work-kit for each car I might drive to work. I have been studying water sources and layup sites along the way. Since the walk home is about 40 miles, this is a non-trivial exercise.
Previously I'd just had warm clothing and boots in each car. Now my kit is built like I really mean to use it.

I hope it's just a thought experiment.
