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?
They might. Of course in practice South Korea tends to return North Koreans back to North Korea if that’s their desire, e.g. if they only wind up in South Korea by accident: https://www.koreatimes.co.kr/www/nation/2024/10/103_168797.html
The other bit is that South Korea does not accept criminals - those get denied and sent back to North Korea even if they beg to stay.
