From the perspective of Central Europe, yielding to the decrepit Eastern empire and allowing it to conquer more territory by violence is a good way to invite more wars of conquest in the near to middle future. Moldova, the Baltics, Poland etc.

If Russia takes Ukraine, Ukrainian industrial base will be used to expand Russian military might and facilitate further wars of aggression and killing of more people.

It is not that different scenario from the one that happened in 1938-9 with Hitler and rump Czechoslovakia. Czech armament industry and Czech weapons were a welcome boost to the capabilities of Nazi Germany.

That's what you get for appeasement. A stronger and bolder enemy.
