I've seen the vice guide to north korea but will look up the natgeo one.
Scary but so fascinating. Mostly because what we know is so little and it's just so strange to see the infrastructure and no one using it.
It's creepy. They were able to film in NK because of an aid program that sent a western doctor into NK to do cataract surgeries. His plan was to do hundreds in a period of days. While they were there they got permission to go to a resident of one of the people who was getting the surgery done. When asked why the lady was getting the surgery done she replied: I want to be able to see the great leader and thank him. When she said that the "minders" (government chaperons) started to cry and soon after the whole family was crying.
Also they interviewed, in SK, a former political prisoner camp guard who was a guard a 50,000 inmate family prison where they imprison the families of politician prisoners. There's 25+ camps like this around the country.
Also the average height of a 7 year old boy is 8 inches shorter and 20 pounds less than the average 7 year old boy in SK.
If there was ever a good reason for us to fight for democracy and freedom, NK is it.
