Really interesting summary, the only thing I would question is the comparison to Nazi Germany. NK doesn't really have any expansionist plans or capabilities (beyond the failed invasion of SK 70 years ago). It was born out of a civil war that resulted from Japanese Imperial occupation and the fall out of the second would war, rather than a series of corrupt democratic votes like Nazi Germany was.

Perhaps more contradictory still, NK was backed by the Soviets who had fought against Nazi Germany.

The only parallel is the level of indoctrination & authoritarianism, but I wouldn't consider those uniquely Nazi beliefs.
