The only one responsible is Putin, nor does Russia have any rights over Ukraine. The age of the Russian Empire is over and the Russians need to accept it. Ukraine is a independent country. No amount of Russian propaganda can change that.
It’s none of your business. Get over your hatred for Putin. He’s not your enemy. The Globalist Oligarchs that wish to destroy America are. They merely use Ukraine as a puppet state for their evil. Putin is putting a stop to that. God bless him.
