It is stated at one point by some CIA guy that North Korea was able to avoid the zombie outbreak by systematically removing the teeth of all of its residence in less than 24 hours. The reasoning being that if nobody had teeth then the virus couldn’t spread because nobody could bite anyone. He states that it was “the greatest feat of social engineering ever achieved”. Like I get this is a fictitious plot but they can’t even avoid making up the most utterly deranged bullshit lmao.
The book is more lib than explicitly racist. In the book, Israel evacuates Jerusalem and lets in Palestine refugees. In fact, their biggest issue is from settlers and ultra-orthodox that are angry about abandoning the West Bank and the old city. The South Africa thing is more messed up, with the South African government adopting an apartheid SA plan that was originally made to evacuate the white population and provide continuity of government in case of a revolution. It's more of "isn't it nice that people can get along with their oppressors?"
