Russia invaded Ukraine, Russia is the aggressor, and to be honest not only am I not engaging with you, I think this is fully bad faith. Russia is the one currently making existential, nuclear threats, too. In fact, reading responses like yours makes me hate Russia's actions even more - they've created so much propaganda that you can honestly write that somehow it's actually Ukraine's fault that they got attacked and invaded by Russia.
Fun fact: the only time when far right had any power in Ukrainian parliament was during pro-russian president. After he fled to Russia they've never been able to cross electoral threshold. They currently hold one (!) seat in the parliament.
That's all you need to know about Nazis in Ukraine.
