Kim Jon Un in a coma

[Snarl]

I or We are very surprised she hasn't gotten rid of him yet.

I wonder what the course of events would be like in that situation.

With in 4 days of his death, a Military General and his Staff and some starving troops will be Framed and Executed for the murder of his wife and children and a coup attempt.
His sister will take control.

Certainly, there would be no dramatics.  What you've described would be a good narrative to drive the succession of power.

God help the South should they decide to lob a nuke that way.  Dramatics are no one's friend in that region.
