The knife edge we’ve been balancing on since 1945 is now held by weak and trembling hands who have never felt the touch of a blade. If nuclear weapons proliferate further the probability of someone using them because they think they can win with a first strike and limit the scale of a nuclear exchange will grow exponentially. Fill your pockets with salt and hope that if it happens the fallout, both literal and metaphorical, is confined to the region that starts it. Maybe a hundred million funeral pyres and a desert of glass will be a monument large enough that we’ll never forget again.
