I am struggling to understand the point of referring to DPRK leadership as non-dynastic despite the obvious lineage. Your point that it is transitioning is noted, but is there some other historically-accurate term for transitory dynasties under socialism? Or is it your understanding that the state was never dynastic in the first place and the lineage has been mischaracterized?
Is there a book you can recommend with perspective on the issue of dynasty in DPRK?
