Will they be exchanged with ruzzia? Or does Ukraine have to trade them with NK?
As soon as the first NK soldiers get captured it’ll be interesting who will ask for their release. Interesting especially on the political side of things. And what happens if noone asks for their release?
Odds are low that Russia or NK will want them back, and after being treated better as prisoners of Ukraine than they were at home they might seek asylum.
Much the same as when North Koreans defect to, or are captured in some way by South Korea. Literally all they have to do is feed them three meals a day and they never want to go back.
