You are committing the same logical fallacy. You claim that the invadad country can have caused a war. No one can cause a country to attack nor can anyone stop a country from attacking. If Russia invades a country, it is all Russias decision to do so.

I think on every legal level this is common sense. Also when a person kills someone, there is no law that lets the murderer blame someone else. He committed the action therefore he has to go to jail. Russia entered foreing borders with their military, therefore they entered war. No other party is to blame for this.
