The peace treaty will clarify that, but I think the more important thing is the establishment of a multipolar world order. That, in and of itself, can lead to conflict, but I also have some optimism that it might bring in a paradoxical peace in the same way that nuclear weapons did. The reason nukes have been good is because it makes it clear that war is unwinnable which effectively ended direct conflict between world powers. Yet of course proxy wars are alive and well with Ukraine being the king of them all. And the US may be unable to defeat Russia in this war, but it's also equally unlikely that Russia could defeat the US in a similar scenario. So, "The only winning move is not to play."

Of course this says nothing at all about relatively small regional conflicts, but in the grand scheme of things I'm far more concerned about WW3 than I am about these. That's not to understate the impact of what can (and is) happening in these sort of conflicts, but at the end of the day I don't think humanity will ever 'evolve' beyond war, and so in the mean time I think the goal should be to not end our species over something that will inevitably look like a pointless waste of life in a few decades. Keep in mind that WW1 was unironically called 'The War to End All Wars' before we started attaching an ordinal to it.
