Indeed.
I don’t expect that the PRK army generals are much impressed with Jong-eun. To say the least. If not Jong-eun, then whom? The doddering Pyong-il? If him, then whom afterward?
Jong-eun fancies that he has a subtle mind. His upbringing is unlikely to have made him aware of his own limitations. The Generals don’t want a North Korean Caligula.
Be some bloodshed after Jong-il is gone.
