It would be interesting if true - the idea, that the dictatorship’s propaganda machine elevating the Kim’s to near godlike status as the “saviors” of the nation has created something so strong - in what the North Korean people believe - that even a powerful military cabal must keep it alive, at least for public consumption, as without it they will not be able to keep their own legitamacy in the public mind.
It also begs a question - what would such a cabal do if somehow all the Kims and all their heirs were somehow eliminated? Would it survive the loss of the Kims or would it lose control of the people?
The military would survive a complete lack of Kims by inventing a new dynasty. Some hero of the Korean war would be found or created. And it would be done before the public learned of the death of the last Kim. And it would work.
The top goal of the UN should be the rescue of the North Korean people. The fact it isn’t clearly illustrates the worthlessness of the UN.
