None of those (comparable to the scale of Ukraine's defense against Russia) worked out, and I say that even for the Yalta Conference. The Sowiets might have had their sphere of influence over Eastern Europe and managed to surpress revolts in each of those countries but ultimately failed. With Ukraine, it has been the USSR's production hub and it is again with a lot more innovation, better access to technology, research and a motivation to survive as a unity. Trump's peace talks are a fool's errand, Ukraine won't agree and it's not in the EU's interest either. The only way to ends this war is to remove Putin and his regime. A fresh start for a democratic Russia like West Germany had post-war.
