Interesting perspective. One could argue that nuclear weapons are among the less harmful things invented, since they killed fewer people than knives, clubs, spears, guns, cars, cigarettes, alcohol, asbestos, coal power plants, and probably a lot of other things. Plus they probably prevent a 3rd world war with killing on the same scale as WW1 and WW2, tens of millions each.
They prevent the third world war, until they don’t. Then they will bring mayhem and misery. And with the current lunatics in charge I am not really at ease just because nobody pushed the big red button yet.
