North Korea is it's own fantasy, in which there is no internet, no free press and televisions are tuned into only one channel. The crowds of North Koreans lining the streets and crying until their bodies dry up is both a sign of true affection and carefully worked manipulation.
North Korea has concentration camps, although they deny it, of which I am told 0.8% (ish) of the population live in. The world though it had destroyed this form of slavery, but of course those who do not study history repeat it.
