Will North Korean Expeditionary Corps Join Russian Aggression?

There have been voices about the anticipation of North Korean military aid to Russian forces attacking Ukraine since February this year. Russian propagandists mention up to 100,000 North Korean soldiers ready for anything, almost russhing to fight. And the government in Pyongyang would only want “little” food and energy aid for themselves, for their revolutionary fervor in joining Putin's army, of course. Of course, this can be taken as another manifestation of even absurd desperation in search of a fresh recruit to the aggressor's army (Russians do round-ups in the Donbass or are looking for volunteers after correctional institutions) or an component of information activities. However, 1 should consider whether this hypothetical North Korean military aid would make any military sense.
