It is unfortunate for Russian athletes etc to lose their opportunity to compete but that pales in signifance compared to the hardship that regular Russian people face should the Russian economy continue to crash in the face of international isolation. I don’t really have much time for whether or not Russia can be in a World Cup or olympics or Eurovision or whatever. That isn’t life or death.
Russia need to be isolated from everything - it’s not ideal but the alternative is we all go to war. The world needs to set a precedent, they need to show other rogue countries that this won’t be tolerated, and they need to encourage regime change in Russia by illustrating the damage that can happen when you invade a country without just cause. It’s not going to happen overnight and it’s awful, but innocent Ukrainians being bombed is worse. We’re past the point of a pain free solution.
