They also told us that “nuclear shelters” wouldn’t work. Not against a volly of bombs by the major nuclear powers but ultimately there were people in Japan who were partially burned by where they were exposed.
Depends on the yield of the bomb.
If you are at ground zero you don’t have much hope but beyond that...
A 20 mt nuke (Our average nuke arsenal) makes a crater 165 feet deep and anyone 30 miles away will have their clothing instantly burned off. They will die very fast if not instantly at that range. 60 miles out you may survive, but medical treatment will probably be unavailable, so you will die a slow agonizing death.
A nuclear barrage of thousands will leave few survivors in this nation you can be assured. There won't be anyone in the country who launched them either.
