I would not condone the Russian invasion in the least but ask yourself just how much better the Ukranians are now than had they been under Russian occupation which I acknowledge is wrong as opposed to living in a country which has been destroyed. .
The Russians began executing people in every town they entered. They have kidnapped and forcibly relocated several million people out of the country, by their own admission.
Ukrainians wouldn't have been living under Russian occupation as Ukrainians. Ukraine as an entity would have been eliminated, because that was the intent, as their own damned propagandists keep announcing: cultural genocide and ethnic cleansing designed to eliminate Ukrainians as a people and thus allow the territory to be permanently incorporated into Russia. Death to anyone who tried to retain Ukrainian cultural identity.
