2.there's no aircraft.
It was your post that sm-100 somehow equals a suitable light fighter.
There's no fighter based on these engines, and no one is even looking into designing it. Maybe North Korea does, but we don't know.
It sadly guarantees that no such aircraft will appear in operational capacity in predictable(+15 years) future.
For better or worse, DPRK will probably have to choose from existing Russian aircraft. They're available, relationship between countries is excellent, and DPRK can pay something Russia needs the most.
Feeding hungry emperor soup in Luoyang - matters.
Chinese are a distant second, but for now it looks doubtful. Relationship between countries somewhat soured, Pyongyang clearly grew restless from depending on Beijing too much, China didn't really show willingness to provide aircraft to DPRK in 2010s, and finally - North Korea can't pay.
