I don’t disagree that the personality cult around the Kim’s is a troubling part of the DPRK’s political culture, I don’t think that kind of thing is necessarily conducive to a healthy democracy. But, this is a country that has been forcibly chopped in half, bombed so much that people were forced to live in caves, and has been cut off from the global economy by US sanctions.
If you expect a country to endure that without issues, then you’re crazy. If you want to end that cult of personality, you should be advocating for an end to sanctions, and end to the Korean War, the removal of US military bases and an internationally mediated settlement between North and South Korea about what the peninsula’s future might look like.
It’s a bit difficult to say how institutionally robust these meetings are, simply because the DPRK is so artificially closed off from the world.
The Cuban electoral system works roughly similar, with direct elections at all levels of government, mass meetings narrowing down to one candidate, and ratification votes at the end of the process. And we have a much better window into how those work.
Obviously that’s a country on the other side of the world, so we can’t just graft the Cuban experience onto the DPRK, but it can help us be more informed in our speculation
