It was because of the Russian offensive that the Germans were defeated. Anyone with an interest in history knows that. Without Russia there was no beating Germany.

D-day landings were 175k men, the invasion force was a 3m strong multinational force.

I disagree that Ukraine should defer to a peace treaty, while the west supports them. It is western hardware that is making the difference. Ukraine knows this. It states it publicly and often. Russia are not making any gains against Ukraine now the Wagner have left the field. What Wagner committed in Bakhmut was unsustainable, and arguably the limits of where it was going to get to. Since Russia is nothing more than a crumbling obstacle now, why would Ukraine give ground to Russia. The Ruble has collapsed. There is dissent at the top now with daggers out for scapegoats. The damage Prigozhin did is still making its mark. All the war is doing is making Russia more and more indebted to China. China is happy to sell Russia arms to watch it destroy itself.

Russia's best outcome right now would be to be able walk away without incurring reparations cost for the carnage they have reaped. However, I doubt this will be seen as acceptable.
