North Korea is a mess. They were banned 2010-2012 from international gymnastics, because they entered one of their gymnasts Hong Su Jong under three different birthdays in three World Championships.
They're arguably the worst offenders of human rights. Poverty is so bad that many people have resorted to cannibalism.
The worst part is that North Korea has nuclear weapons, so no other country even dares to invade. The people has no chance of overthrowing the regime either, so they're literally trapped.
