S. Korea would not be the only nation sending in food if this goes down...they’ll be a mass entry of food from the International community...and very likely on standby currently.
This is not going to be a case of blackmailing succeeding this time around....not without a change in N.Korea’s leadership.
I think we’ll eventually see Kim ushered out of there....the Chinese taking over...but pretty much on the hush in order not to rile the cult followers.
Not sure why you believe that. Thus far this Kim has done nothing that wasn't done before and his predecessors were not ushered out of there. I think what you say could happen if he goes too far but thus far he hasn't made that move yet.
