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.

Defecting to a country at war with the DPRK is treason, just like how the ROK treats those defecting to the DPRK. This isn’t especially uncommon. People from the DPRK leave and visit Russia and China frequently, the biggest obstacle to movement isn’t the WPK but instead US sanctions.
