My dad was privy to nuclear war for the DoD as he did war games back in the 80’s at what was once a major SAC base Kelly. He passed in 2002 but he told me since it was more than 30 years and just before he died
Won’t be just one per city, but multiple, San Antonio would take between 7 to 10+ estimated of various tonnage. Other cities would also get multiple warheads, SO, IF IT DOES HAPPEN expect that as they will use just about everything they have. The variable is how fast we could destroy launch areas after the first volley, but it still will suck when 2 or 3 county busters get here first.
Russia has bunkers everywhere and the Moscow subway that was built for just this. We have nothing but a few fallout shelters that used to be stocked with tins of water and crackers, but no longer, and they took the radiation symbols down from the buildings, so find a 50ish year old that remembers where they were. Most old court houses were designated fallout shelters and basically any building that had a basement below surface.
Good luck, you’ll need it.
It won't happen. People are required to do what they can, yes. But ultimately such an even is in the hands of God. And despite appearances, God still loves us.
The Moscow subway is a city underground. The shops and eateries would be emptied in a day but count on there being plenty of emergency supplies stocked for quite some time.
