It’s a good question, I’d like to understand the decision making process as well. What are the rules here? But whatever it is, there is ZERO chance that we (Czechs), Finnland or Sweden (at the very least - I do not know the positions of the other European countries one way or another) will accept playing against Russia while they are still waging their aggressive war, so whatever the decision-making process is, from a practical perspective it is hard to imagine the IIHF will force a situation where many European nations will boycott international tournaments.
