This story has been posted 500x. 2. Almost all reports in the last couple days have either dissed the reports/news saying this and have offered speculation that he is not dead from sources just as/if not more reliable. I echo the comment from /u/purpleheadedwarrior
> The outlet reports -- citing a Chinese medical expert privy to the situation -- that Kim had clutched his chest in early April and fell down while visiting the countryside there. He needed a stent procedure done, but apparently ... it either wasn't done rapidly enough, or it was botched completely by the surgeon -- with some reports saying he had shaky hands.
-Kim Jong Un was last present at a WPK meeting on April 11th, where he sacked the Foreign and Defence ministers and replaced them with people supposedly loyal to Kim Yo Jong, also (allegedly) announcing that, "if something happens to [him], Kim Yo Jong would be [his] succesor." This is the last time he is known to have undeniably spoke himself.
-Beijing media usually doesn't play around when it comes to speculation on the health of the Kims. The fact that they're involved means things are serious most likely.
-Kim Yo Jong has allegedly been serving as commander-in-chief, issuing orders according to a Japanese expert.
-Pyongyang recently went under a state of emergency, most likely due to the growing concern and possible spread of COVID-19 in North Korea.
-50 people of unknown profession (likely doctors) left Beijing for North Korea on Thursday for unknown reasons.
What we don't know yet:
-Why Kim Jong Un's train is at Wonsan - it could be either ease of movement post-surgery, or preparations for a serious procession, cwlling back to Kim Jong Il's death.
-The leadup to this event.
-Obviously, the current state of Chairman Kim's health.
-There will be no power struggle, much less civil war, in North Korea. Kim Yo Jong is firmly in control since April 11th, and unlikely to lose her authority.
-Kim Jong Un is more likely dead than in a vegetative state, considering the latter is brain-related and probably wouldn't be caused by a botched stent procedure.
-Kim Yo Jong is not more brutal than her brother; as presumably a leading advocate for inter-Korean and Pyongyang-D.C. diplomacy, reunification of the peninsula is more likely than ever shall she take power - although I doubt the Kims are going anywhere.
-The prospect of a non-Paektu supreme leader is more tossed around than you'd think; it was commonly expected that it would happen after Kim Jong Il's death as a regency until Kim Jong Un took over, with Jang Song Thaek as leader (obviously, that did not happen) and for a time it officially did happen, as from 1994 to 1998 Kim Jong Il could not take power as supreme leader due to the Arduous March (although in practice he still led the nation).
-If Kim Yo Jong takes over, don't expect much change domestically. Perhaps a few token economic and social reforms like her brother, but North Koreans will still be extremely oppressed.
That's just my own thoughts from research, though. I'm no expert, of course, and open to hear anyone else's thoughts.
My two main sources are the Shūkan Gendai article (aside from the last three pages which are weird and kinda play into the "NK is falling apart" narrative that gets pushed often) and some post here a few days back from one of Japan's top Korea experts on Kim Yo Jong, not to mention the transcript of the WPK meeting on Apr. 11th. As for my views on the army-party conflict, its mostly comparision to the lack of any destabilising events in NK, along with US, PRC, and SK contingency plans - as it often goes disregarded that if Pyongyang's enemies are planning for what happens if Chairman Kim dies, then certainly it would, too. Furthermore, the military doesn't have a unifying figure and IIRC gets changed around often, IDR where I read that though.
Utterly disgraceful. The West is and always will be, jealous of the DPRK and its glorious society. They will stop at nothing to bring Marshal Kim Jong-Un down and throw the DPRK and its people into uncertainty. They must never be allowed to prevail! Long live Marshal Kim Jong-Un!
