I wonder if people see how safe our world is today. I don’t think most people do. I think that the news media paints a good picture. Have I noticed that society has become progressively safer as more destructive technology has been invented. If you asked me if nuclear weapons makes society safer, I can’t tell you if it’s just a correlation. But I bet the graph would look like this: It seems as if the most brutal societies are the ones that fight with hands and teeth (such as lions), and then those that fight with knives and swords (isis). The safest societies are the ones that fight with hydrogen bomb nuclear weapons (USA and China). Do you think this is just a correlation?
