The UN/US somewhat invaded Ukraine by provoking and supporting a long lasting and deadly citizen led coup, in reaction to the Ukraine president choosing the Russian oil/trade deal, rather than the UN deal. We helped with their following election, installed a puppet president with and heavily embedded our people and money in their government's workings. That government, with our help, intelligence, and constant supply of weapons, where used to attack Russia and violate Ukraine-Russia peace treaties, while using morally questionable means to drive the more Russian populations out of Ukraine.

The only a question is how much of that coup and aggression towards Russia was Ukraine's own doing and how much of it was the result of US/UN tactics, pressure, and money incentive. The vagueness of blame when hiding behind proxy wars.
