You are determined to believe the Russian lies because your religion would be shattered if you were to acknowledge the truth. Ukraine was once a very corrupt society. How could it be otherwise, having been controlled by Russians for so long? Even after the Maidan it was still bad. Remember Biden's famous episode re: Burisma was under Poroshenko. Poroshenko is why a political outsider, Zalensky, was elected in 2019! And the news has been full of stories like those I posted ever since. Did you even bother to click the link?
So, you're claiming it wasn't after the Maiden coup?! This is the country where Hunter got his phony job from a Ukrainian oligarch. George Soros was named the second most important person in the country before the war. And, neo-Nazis were part of both the government and military.
All I need to know is that the front moves ever-westward and the criminals running my country seem distressed. You have poor choice in causes and friends.
