Under the Loving Care of the Fatherly Leader: North Korea - download pdf or read online

Less than the Loving Care of the Fatherly chief bargains in-depth photographs of North Korea's ruthless and bizarrely Orwellian leaders, Kim Il-Sung and Kim Jong-Il. Lifting North Korea's curtain of self-imposed isolation, this ebook will take readers within a society, that to a Westerner, will seem to be from one other planet.
