Totalitarian. The specific flavor is Juche. It started as an ostensible offshoot of Marxist-Leninist ideology, and then became whatever the ruling family wanted it to become as time went on. By now, its essentially just a cult of personality/deification ideology around Kim jong un.
North Korea is absolutely not socialist or communist in any meaningful sense.
If everything is shared under communism, that would include political power. That makes communism (IMO) a direct democracy. Does that sounds like those countries to you?
They claim to be communist in some cases. Socialist is also a sort of blanket term which “means something” which - is somehow different from what others know it as. And “liberal” is an insult, so. They’re very confident they’re “left” of all creation, and any real-world effort to help people through existing national political structures is obviously corrupt and unworthy of examination.
