If you search out North Korea documentaries, there is a complete eye opener about that place.
I've watched plenty of them and they are very interesting.
I do not support North Korea "at all", but I understand why they act the way they do... it's just miscommunication, misunderstanding, and not a lot of compassion.
It's all about ego and military. It should be about talking, and negotiating better.
It's an awful mess, it never should have reached this point, yet it is still escalating and won't stop.
