It makes me wonder if it never occurs to them that while their tech has stagnated from embargoes and lack of advancement, our's keeps growing.
As long as they have a nuke and a fuckton of artillery pointed at Seoul, they don't care.
I remember watching the VICE guide to North Korea. There's a part where, as a part of the government-run tour, our heroes visit a bar with a karaoke machine that happens to be very close to the DMZ. However, because it's a South Korean machine, it came pre-programmed with songs that would otherwise be banned in the DPRK. One of those songs was "Anarchy in the UK". One of our heroes sings this song, but the government escorts who are
stalking spying on accompanying him are like "lol wtf?" because they have no cultural context for the song whatsoever. They thought he was either drunk, or making fun of a military ballad. The VICE dude later said that he realized at that moment that North Korea was like a time capsule perpetually stuck in Soviet Russia.
