I agree but it is still curious. Usually, there is a need for "peace" from an imperial perspective because the chaos makes asserting imperial sovereignty messy. So the ceasefire talk is something I would expect a sheepdog role player to agree with as long as he can avoid condemning the occupation or the "right" for the occupiers to persist with their crimes. But he doesn't even do that, he won't even go along with the ceasefire minority. I'm not sure what he really gains from this other than not having to hide his true power as an imperialist anymore. The US regime has been a little extra aggressive on this war, probably because it is closer to American settler-colonial "home" than Ukraine, and Bernie is something of an example of this.
