Just two years on the job and armed with nuclear weapons, North Korea's Kim Jong-Un is the world's youngest dictator, ruling one of the world's most isolated countries with an iron fist. Like his father and grandfather, he is trying to maintain tight control over what the world sees of North Korea - and what North Koreans see of the world. But as FRONTLINE reveals in Secret State of North Korea, cracks are starting to appear in the regime's information barrier, and it's becoming more porous. James Jones, director of the FRONTLINE episode "Secret State of North Korea," talks about the documentary, which airs Tuesday night (1/14) at 9:00 p.m. Central on SDPB-TV.
