That there was cause to use nuclear weapons is a myth. That there could again be cause to use nuclear weapons is a myth. That we can survive significant further use of nuclear weapons is a myth. That there is cause to produce nuclear weapons even though you’ll never use them is too stupid even to be a myth. And that we can forever survive possessing and proliferating nuclear weapons without someone intentionally or accidentally using them is pure insanity.
Only sometimes though.
My history teacher was adamant that Nixon was the best president in history (aside from all the illegal stuff).
