Per Wikipedia - not always totally correct and since this IS North Korea we are talking about, who knows what is true or not. But the eldest son is 37 now - old enough to take over. The weird thing is that the Troll Doll's father made his son prominent and gave him powerful offices and positions in government before the father's death, so the transition would be easy. Troll Doll has not done this, to my knowledge.
They'll probably treat him the same way that I think the Cuban-comms are propping up Fidel; like a demented version of "Weekend at Bernies" North Korean style. I think some of them still think that Kim Il-Sung (Kim Jong
mentally-ill's father) is still alive.
I'm laughing my ass off over your use of the term "Troll Doll"! Too funny!
