Thanks for the input. Yeah it seems pretty tough for any ole American to just cross the border. And that's a good point that someone could try working there legitimately which would give the DPRK some sort of real relationship to vet you with rather than just common ideology that any spy could receive training to fake. And any foreigner working there is probably aligned anyway.

Maybe if any random non Korean person just jumped the border the DPRK would rather you have just gone to another socialist country more integrated to the world instead.
