It is telling that the Ukrainians are hitting logistical targets inside Russia, and the Russians are hitting apartment buildings in Ukraine.
I can't remember where I read it, but somewhere I saw a study which tried to step back and answer the question "does this tactic of killing innocent civilians to break a country's resolve, actually have that effect" and the answer was in almost all cases an absolutely resounding fuck no. As you would expect, it just motivates them more to fight you and win.
Even taking the going-to-hell aspect out of it, and just focusing on Russia trying to win the war, them bombing civilians is a pure and counterproductive waste of munitions and of their own military's time.
