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.

Like it or not, the leader derives his power from the populace. An autocrat is powerless without people going along.

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.
