There are reports of 43,000 civilian casualties (12,000 deaths) in Ukraine, but most agree that the number is MUCH higher. Several estimates are that over 100,000 civilian deaths. Russia has over 800,000 casualties. Ukraine has between 400,000 and 500,000 casualties.
And who knows what Putin would accomplish if the rest of the world didn't stand up to him. Putin is less efficient, but that is mostly because the world now knows how horrible people can be given the chance. Russian military intentionally attacks civilian locations. They are raping and killing women and children.
