That's an interesting question. I think nuclear weaponry's omnipresence in timelines stems from the natural discovery of the power of the atom with advancements in quantum physics. Once an atom is split, and a society discovers the conversion of mass into energy, the potential energy of nuclear fission is obvious. No society can learn basic atomic physics without concluding that that energy can be harnessed for a weapon. That's my two cents anyway.
