Comments in r/sports often make make me question my fandom sometimes.

This seems like an obvious call to me. I'd feel for the athletes that don't support the war, but if you are having a giant get-together of the world's best athletes, seems like the bare minimum requirement for a country to get in, don't currently be murdering innocent people in a baseless, unprovoked war.

If you want to include the US if they are ever doing that (or any other country) cool. Yes it's mostly a symbolic gesture, but, you know, that's actually important too.
