Communism

Hi everyone, I know this isn't 100% on topic but this seemed like the closest fit. You all tend to be more generally knowledgeable than the average Lemming. Feel free to remove if it's too off topic.

In the last few years, I watched what I believe was a YouTube video on South Korean misinformation about North Korea. It discussed defectors, the conditioning they receive after defecting, and celebrity defectors. I recall it also interviewed some North Koreans living in South Korea.

Does anyone know the video I'm thinking of?
