Of course it would not end South Korea. But South Korea geographically is in a much weaker state than Japan was during WWII. First, half of South Korea's population is located in Seoul. Second, Japan is roughly three times as large, and has many more cities with larger populations. Needless to say though, any war is tragic, and hopefully a continuation of the war via violence will not happen, and especially not with nukes.
