the guy has his pancake mixer in his EMP cage
Not to scare you, but look up TETRA radiation, and what the government is doing with that.
EMP doesn't concern me because if we get an electromagnetic pulse that destroys alternators in cars and most electronic circuits that can only mean that a 1 Megaton or larger nuclear warhead was detonated somewhere above the center of our country at an altitude of 20 to 50 miles. IOW, Nebraska would be right under it and receive the strongest pulse. That was signal the beginning of a nuclear war. You and I would probably be dead. Survivors would be down wind from Denver and the West Coast targets. South winds would bring up fallout from Kansas City, Dallas and Huston. Northeast and East winds from Chicago and points East.
Bottom line: very few long term survivors. It would be Chernobyl on steroids. Radiation levels so high that environmental disruption would guarantee life threatening difficulties for all survivors. We aren't talking about returning to the 1800s. This would be stone age stuff. Everything you find to eat, or to make shelter would be radioactive. You would lack the medicines to treat the resulting radiation sores, which would get infected. MRSA on steroids. These are facts that the idiot running NKorea doesn't understand. He would not be immune from his little war games, even if he hid in a bunker 500 or more feet underground with enough food, water and tapes of John Wayne movies to last him for 10 or 20 years. When he climbed out he'd find that the radioactive isotopes with half-lives of 10,000 years haven't even begun to loose strength, and they would be everywhere and in everything. All of his slaves would be dead, and he doesn't have the brains to make toilet paper to wipe his butt.
