The mass media continually focuses on the threw north Korea poses to other nations. But it isn’t a real threat.
North Koreas strategy is well known and well understood. Their regime survives by making trouble for the west, to suit China, their sponsor. As soon as north Korea actually carries out any of their threats, they will be militarily defeated and their regime ends. Everyone knows it and so do they. The war industry also benefits from it, as military standoffs punctuated by regular minor conflicts and proxy wars, benefit the war profiteers. Full scale war doesn’t benefit war profiteers because regimes cannot be preserved.
The real problem is the imprisonment and exploitation of the powerless north Korean people. Their freedom and lives are sacrificed by the regimes that benefit from the standoff: China, USA, Russia and north Korea.
It is always the establishment that is most responsible for the suffering of people.
