After Ukraine and their NATO backers blatantly violated peace treaties, Russia entered an already ongoing civil war where Ukraine was illegally and violently trying to ethnically cleanse a minority population within their own borders, killing men, women, and children while doing so, and they did it in front of all of us. Those are the facts, and you can confirm it with any independent news source.
Russia doesn’t have a long list of breaking peace agreements or invading sovereign countries. On the other hand, NATO, particularly the US, have a disgustingly long list of violently invading countries under paper thin pretexts and lies. It’s not Russia whose word isn’t worth jack shit.
