If my airforce was comprised in bulk of early to mid era cold war museum pieces with a (very) small handful of late cold war era jets as my flagship units then I would be impressed with anything developed after 1991 as well.
I mean, that’s fair enough in itself. There’s plenty of nations out there still rocking their Falcons, Flankers, Frogfoots, Frogger, Tornados, Mirages etc etc completely respectedly. But they also allow their pilots more stick time in half a year than the vast majority of NK’s pilots get in half a decade.
