start getting military help from China
That would imply that the Chinese government is dumber than Putin, which I really doubt. China will sit on the sidelines for as long as they need to so that they can get Siberia on the cheap.
Anyone dares to do a cost/benefit analysis on civilians if Ukraine accepts the terms or at this point they're pretty much committed to just being a pawn and have no choice but to be a battle ground for this east vs west game to their last citizen?
What are you still babbling about? What "terms"? Denazification? Putin lied about everything and is still lying so there isn't any trust in him that would make some mythical "terms" feasible.
Funny how you talk about "pawns" in the same sentence where you're implying that the Ukrainians can be just told to accept "terms" and stop fighting. At this point it's very unlikely they would do so and it's getting less likely with every civilian death. Threatening them with more civilian deaths is not going to make them want Russian "terms".
