At what point are the citizens of a country responsible for what the country's military is doing?

Note: not advocating for a nuclear genocide, but I do feel that citizens become culpable if they are allowing their country to stop on others and they aren't protesting or emigrating (if possible)

Nope, I'd think that if ever something so bizzare would happen it would be tactical nuke targeted at bigger gathering of wagner forces. Little hitler at power there wouldn't care of a village or two got wiped if alternative was coup succeeding.
