Lil Kim is a bad dude - granted. Not arguing that point. If we give him the office similar to the Emperor of Japan (non-executive symbol of state) and the premiership to the current president (or pm), this could create reunification. Lil Kim could still be the weird dude he is, but without the ability to harm others. His kids, if he gets any, would be looked after by the Imperial Household Agency - just as they do in Japan. This will ensure a proper upbringing with accountability to the govt. Park is already an elected leader, now she will have to face confidence votes in parliament like any other elected leader.
When Korea was split in 1945 with the DMZ on both borders,it was clear that there was political tension between Communist Korea and Unitary State Korea meant the Divide between the two.Putting them together nevertheless is a disastrous idea because the tension will impact each other thus spawning a war or fight over the two and that wouldn't benefit each other.Furthermore, who in the right mind thought that putting North Korea to combine with South Korea would actually be successful.That's like me telling North Sudan to come peace with South Sudan, you can not do that.It's practically difficult since the two have their own views on a situation.
