People from the DPRK do leave it and visit countries like Russia and China, they just can't defect to the ROK legally. You keep claiming there are hundreds of videos of troops from the DPRK killing civilians defecting, but it's often ROK troops shooting them. Cuba is not at war with anyone, and both Cuba and the DPRK are harmed by sanctions, the major reason the DPRK is doing better is because it has nuclear deterrence.

if you're an american, the federal gov't is legally obligated to share cia/fbi/state department/etc. files through a system called the freedom of information act.

do yourself a favor and read those files and learn about how they have openly created propaganda about north korea to get you to believe what you just wrote.
