That's up to Koreans to decide. As a Taiwanese, I don't advocate unification by force. If NK as a population doesn't want to join SK, that's their choice. But the matter of Un threatening war is a separate matter that needed dealing with. I leave that to China.
No stance, it is not me who is risking my life. But if NK can just modernise with the help of China we would all be better off.
Only if Un is desperate.
Only if Un strike first.
Collapse and modernise. But it can be tomorrow, or two hundred years from now.
NK would use a nuke only with great difficulty so either initial strike or not at all. No one else would bother to nuke them because it is not need. Conventional bombs would do.
So what is you stand in NK crisis?
Will NK attack SK?
Will NK invaded by US&SK (or china or other country)?
What is the future of NK?
Do you think NK or US (or other nation) will use their nuclear arsenal?
