It has to be reasonable to believe that there at least ten NK military people, either fighting. Training, supervising, working on equipment, etc., in the side of Russia, based on info in The Economist magazine
There is already reason to believe at least 10 NK technical advisors are operating in the Mariupol region. While UA military denied reports that NK soldiers are on the frontlines in Kharkiv, other officials confirmed reports that "10-15 people, mostly, as it seems, officers" are in Ukraine. There is also evidence of NK presence in Melitopol and Donetsk.
@spiderduckpig thanks. I'm not denying this in any way, just trying to be cautious about believing things before very clear evidence is obvious.
There are quite a few NO holders. I'd wonder what they would say or what might convince them to shift views. for me, time plus confirmation of the fact with visual clear widely shared evidence reported on (not just reprinted) by global news orgs, not just ones closely related to the combatant nations and close supporters My background: still mad at nyt for buying and spreading fake Iraq WMD all over the world to start a war, when they should have known it was a setup
