Right, which is why I said its effectively what we have now (a situation that preserves their current territories), AFAIK, the situation barely effect SK life.

Right, which is why I said its effectively what we have now (a situation that preserves their current territories), AFAIK, the situation barely effect SK life. It's just neither side believes the minute they stop pointing weapons at each other's borders the other side won't take advantage, and as far as I know, prior attempts to sit down and end the war officially require the other side basically give a full surrender. There's also a Chinese interest in keeping DPRK (it was Chinese MiGs American fighter pilots engaged in the actual war and I assume currently supplies DPRK with arms in a similar role to the US and SK) as a buffer zone, and a source of cheap labor and source for human trafficking in some cases. So both countries have a larger country/acting ally disrupting the politics.
