Great discussion here guys! So, it seems like the USSR wouldn’t have had much power to nuke the US mainland but did have power to possibly use nukes in Korea and probably Europe.
It could also be argued that if nukes were used by either side, it would make nuclear weapons more “conventional.” In other words, if the US nuked North Korea and/or China (forgetting about the political ramifications for now), it would “desensitize” the world to them, which would mean that they would be used much more often and obviously cause much higher casualities.
About the casualties - if you think about it, up through WWII, each war being fought was causing an exponentially larger amount of death. By using nukes, the higher casualty rate could just be attributed to “the next step of technology.” In other words, even though millions could potentially die, it would still probably be less than WWII and might have been accepted at the time since each war brought more powerful weapons (in less than 50 years, the world went from Roosevelt’s Rough Riders to a B-29 dropping a bomb that killed 200,000 people at one time, so if that was accepted during WWII, why wouldn’t a 1 or 2 (or however powerful bombs were in the early 50s) megaton nuke that can kill 400,000-500,000 people at once be accepted?
