He doesn't list any sources for anything he says anywhere in the video, which is a surefire sign that he's probably just copying from Wikipedia and the first page of results on Google. In the DPRK part of the video he talks about supposed human experimentation in North Korea, the sources of which are just, well, defectors (including defectors who literally do not exist) who are contradicted or questioned by other defectors.
In any case it's like North Korea is being included here as the token "gommunism bad" country, when the rest of these are all, you know, Imperial Japan, Nazi Germany, Apartheid South Africa, and a whole five different experiments by the United States. Also, speaking for myself, I'm just kind of tired of "countryballs" in general. There was a while when the only upload of "The Red Flag is Raised" had a little Palestine countryball in the corner, and it just bothered me.
