The real thing that stands out to be about this situation is that Zelensky STILL has not given the soldiers trapped in Mariupol permission to surrender and expects them to be be willingly annihilated. This seems like it's pretty much unprecedented in modern times. Generally the European way of war is that one side fights until the situation is completely hopeless, then surrenders. But of course Zelensky isnt a real European and doesnt see Ukrainians or Europeans as his people, so it's not at all surprising that he just regards them as disposable cattle.
