The more I think of it the more likely I see Russia vs Iran or Indonesia becoming. Mind you they won’t ice Ovi for those games, rather a roster of KHL-2 farm league players making up a team.
The problem is they will have to be voted in, that means the IIHF member countries, of which many are Eastern European, will have to want to be gracious to giving an exception - and generally their feeling now is in no way accommodating to that.
Unless there is a revolution and regime change, I don’t see Russia returning to the top division.
