There was a report about ten years ago that said that the Cuban diplomatic community in Pyongyang, along with other "progressive" missions, sent their kids to a camp somewhere outside Pyongyang. I just can't imagine what kind of "fun" those kids had at camp. "Okay, kids, now for lunch, we're going to have a toad roundup. What we don't eat for lunch, we'll have for dinner!"
And no amount of reports, documents, photos, or defector's stories will change their mind. They also honestly believe the reports of 99% literacy, low infant mortality, high life expectancy etc. etc. Because we all know Castro and Kim Jong Il have no reason to lie.
