You're close. Some thoughts of mine.
Fat Kim's dad was probably already dead or replaced in 2008. None of his official appearances since then could be verified.
There was an attempted coup though in 2008, and many old guard army leaders were purged for opposing nukes (there was a six nation disarmament plan including China).
One nuke test before 2008 and so many post 2008. Post 2008, NK also started "opening up" and its full of surprises.
This is a "startup exchange program" started 2007-8. Link also shows media sponsors in first page with likes of Wapo, Forbes, Tedx etc
