I don't get Kim Jung-Un.
Dude grew in Switzerland, seemed to be a fan of NBA and basketball in general and was most likely raised by western standards.
Then, why does he follow his father's way ? Considering his lineage, I don't think that somebody would have dared touch him if he'd changed NK's foreign policies and opened this country to the world. Coulda entered in History by being more friendly with South Korea and the world but chose to continue that NK bullying bullshyt policy...
He sees what happens when dictators give up their weapons programs. They get invaded by the US Saddam, Ghadaffi etc. It wouldn't end well for all his father's loyalists and i'm guessing extended family members who have been good in Korea all these years.
