Nuclear war is survivable for the elite in their underground bunkers, and they're the ones who get to decide if it happens. People live in Hiroshima now, its not like everything turns into Chernobyl. If you survive the initial blast you have to stay inside for a couple of weeks until the radiation deteriorates. But then you'll probably starve unless you're surrounded by preppers like in Utah. I think its going to happen but not for a few years.
