Supposing WWII ends earlier, whether by a smashing earlier Soviet victory or the Germans having everything in their drive to the West go wrong for them, what happens with nuclear weapons, given they weren't invented until August of 1945 IOTL? IMHO the Soviets will develop them first due solely to being the only state with the ability to spend the time and money on that project with no accountability to anyone but its own leadership, but I might well be wrong about it (and my argument relies solely on the skepticism that would exist about the expenses of such weapons without Hitler as a motivating force in peacetime societies). If the Soviets or someone else in this scenario do develop the weapons first, what happens to nuclear strategy ITTL?
