Like the 2,000 or so nukes set off across the world, several dozen of which were burst at extreme altitude? Guess what, we are still here. The "1-nuke-at-altitude-and-we-go-back-to-the-stone-age" is BS. Yes, I read One Second After. Good book, but it is still FICTION.
When I was with DOE/NNSA, I was able to visit an SS-18 site being dismantled in the mid-1990s. When we talked to the Russians about their big 25MT warhead on some of them, they said that it was for the LCCs in the Minuteman/MX missile fields, which makes sense. (Anyways, never trust the russians. IIRC those 25MT warheads were dismantled at their Pantex Plant equivalent in Russia).
The article claims a single emp.
