 I don't know if it's 100% credible, but that is the nature of all defector testimonials. In an interview with the South Korean newspaper Chosun Ilbo, Ri Il-kyu says he became disillusioned with the North Korean political system. He says he got an unfair job evaluation and that his request for medical treatment for back pain was denied. So late last year, he decided to defect with his family and was apparently able to get a flight from Cuba to South Korea.
