Amusement has nothing to do with it. This is one method among many for pursuing national geopolitical goals. It's a shame that the Russian populace has to suffer, I bear them no ill will. But if they ever want to get out of international sanctions then they know what they need to do.
Buy a ticket to Ukraine right about now and ask Ukrainians how amused are they. And don’t forget to visit every country that had to take millions of refugees.
