If everyone has nukes, the probability of a nuclear exchange goes towards 1. The probability of nukes landing on your city goes towards 1. We survived the last seventy-five years due to a relentless geopolitical exercise in limiting the proliferation of these weapons, often at great (moral and concrete cost.) We won’t survive an environment where every single tin-pot dictator has thermonuclear weapons mounted on ICBMs.
