With Russia becoming bigger problem Kim has lost that position, and looks like he is trying to get at least some of the former attention. And there is no notebooks, and nobody writes each and every word of the dear leader into the notebooks - add to that the leather jacket, and it looks like NK is undergoing reforms/modernization moving itself into their version of 21st century. The rocket launch video from the drone is almost like SpaceX video from the on-board camera :)
Interesting that they clearly show where it is happening. And in general NK isn't that big to hide these large missiles and their trucks.
Btw, am i the only one who hears them screaming "Banzai!" (https://youtu.be/0PGMXz_X8K8?t=120) - to me it looks a bit out of place for a national propaganda in a Korean state.
