Be flippant if you want, but the Soviets were much more aware of and dedicated to civil defense than we ever were. They had exercises where they evacuated whole cities. They had plans to ship factories to wilderness lands and bulldozed dirt over the machines to recover them for the times after the nuclear exchange had ended. They had TV public service instructions teaching the people how to shelter during a nuclear blast. Civil Defense was a branch of their military forces with the ability to martial all resources when needed.
With that kind of heritage and legacy I believe they would have far more survivors than we would with our bend over and kiss yourself goodbye mentality. That thought actually disgusts me.
Don’t forget their subway shelter system, too.
Their subway stations were fallout shelters.
If I ever get the chance to visit Moscow, going to those stations would be on the top of my list, they did a great job with those. No graffiti there.
