No way SK is going to convince NK to abandon nukes. The point of having nukes is not to intimidate SK or JP. It is to deter the US.
what is south K up too? this has ZERO possibility of happening, is this so this is about some domestic/international politics framing NK as unreasonable and antagonistic so that they can buy more US weapons? or is the real issue that NK has forces embeded with the Russians who are are learning how to fight a now conventional but ultra nasty drone war and with the US becoming completly unreliable, SK is readying to make a LOT of concessions to NK?
How realistic is this? While North Korea has apparently recognised South Korea, the hostilities will not cease or end from the North Koreans unless South Korea stops hosting American military on its soil. But does South Korea feel confident enough to defend itself without the Americans? As a superpower, is the US willing to forego a military presence in that region? Under what conditions will China / Russia allow both side to repair their relationships? Both China and Russia really upped their ante against the South Koreans, by helping the North Koreans upgrade their military, when they made public their intention to join the AUKUS alliance ( https://www.scmp.com/news/asia/east-asia/article/3261039/fir... ).
