The political-media elite clearly think ordinary people are completely stupid and totally gullible. Currently they are pushing two mutually exclusive narratives about North Korea. One is that North Korea is run by a dangerous dictator, who has the capacity to wreck massive death and destruction on neighbours in the region and even possibly on the western coast of America. The other is that North Korea is such an ecomonic basket case that it cannot even feed its own people let alone produce serious weapons, resorting to using fake weapons for its military parades.
The point about these narratives is that they cannot be both true. Indeed, it is possible that neither of them is true. So, let's ignore the lying political-media elite and think for ourselves. An obvious question is what do North Korea's neighbours think. Its closest neighbours are China, Russia and South Korea. Both China and Russia are opposed to the sabre rattling by the US. They are in favour of North Korea abiding by UN resolutions, but are equally supportive of international law, which does not allow force or the threat of force against North Korea for violations. South Korea's position is slightly more complicated. The ruling elite are concerned to represent North Korea as a threat, as part of their long standing alliance with the US. However, many ordinary South Koreans see, not North Korea as a threat, but the stepping up of tension, specifically the current installation of a US missile system, which threatens not only North Korea, but also China and Russia.
The logical inference to be drawn from these considerations is that the stepping up of tension between North Korea and the US has little or nothing to do with any supposed threat from North Korea, but is rather a justification for a further development of the military encirclement of both Russia and China. This is a dangerous strategy, for neither Russia nor China can fail to notice, nor can they fail to see the increasing encirclement as anything other an acts of aggression, and, as any self interested actor would, take action to defend themselves.
However, the political-media elite cannot simply explain the military build up honestly, as the vast majority of people would be opposed to such military adventurism. This is why they are reduced to absurd narratives: on the one hand, painting North Korea as massive military threat, and on the other, painting North Korea as a complete failure that is incapable of any effective action. North Korea is not the threat - the threat is US militarism.
