What is in vain in fighting for Ukraine?

Families destroyed. Men and women killed. Children died caught in crossfire. Women getting raped by Russian soldiers (and I suspect even men gets raped as in the cases of wars in Africa).

All in the name of bringing back the glory of USSR as promised by Putin a long time ago if he becomes president.

Ukraine falls, Europe falls.

Tell me if a woman is worth turning my back against the plan?
