“Traitor´s Guide to North Korea” by Morten Traavik is a really good starting point for liberals to get a viewpoint from a westerner about this country :) i can highly recommend it. It´s from an artist´s point of view and demystifying the country. E.g. this dude took a Discoball around the country to take pictures because it´s fun and north koreans are… shocker… people.
