"a North Korean Holy Trinity - father, son and Great Mum"

It's (back to) the Cult of Lenin, the Cult of Stalin, the worship of mass-murdering secular deities.

The old D&G question: why does desire desire its own repression?

or: Why does the human brain derive so much pleasure from political masochism?

In modern times relatively few tyrannies managed to reach this pitch of religious personality worship: Germany under Hitler, China under Mao, North Korea as shown, but probably not Cuba, Vietnam, perhaps even Russia. Something very deep and gone in the human animal is obviously triggered - something that must be part of the religious wiring IMHO.

Apologies for tautological emptiness of previous, remains the case however that significant distinctions suggest themselves at a threshold where tyranny crosses over into something at least quasi-divine (D&G-style despotism). Hard to know whether this tells us more about the essence of politics or of religion.

Missing word so far (of course) - 'Messianism'
