Something I’ve been thinking about for the past week is whether the United States would choose to use tactical/battlefield nuclear weapons in the event of a North Korean invasion of South Korea. This hypothetical war could occur at any time after the end of the first Korean War, and let’s assume that North Korea uses sheer numbers to overrun US/RoK troops and push them closer to defeat/stalemate by capturing and holding a vast portion of the South. Now obviously using a nuclear weapon to slow the North Korean advance would eliminate a portion of the KPA’s remaining first rate troops at such a stage of the war, but I doubt the RoK would let US nuclear weapons fall on their own soil, not to mention the DPRK retaliating with their own nuclear arsenal. Thoughts?
