The real big losers of the war in Ukraine are the UK, France and Germany.
They lost economically and militarily and thus lost their morale in the European Union. The world order in which these former powers still had relevance is over and now they will have to reinvent themselves or disappear.
Russia and the US have seen that they cannot win unilaterally and will have to make a deal in which both will concede part of their plans. Russia will get Donbas and Crimea, and the US will gain control of the exploration of rare earths and western positions in Ukraine.
But those who can be called "winners" of the war will be Poland, Italy and Spain, who will take advantage of the weakness of Germany and France to increase their influence and desires in the EU.
For Ukraine, the result will be mixed. The old artificial Ukraine, with its Orthodox majority population and Soviet borders, has been destroyed, it is gone forever!
But a new Ukraine should emerge better than the one that ended in the long run. The dominant part of the male population will be Polish/Ruthenian from the west of the country, will continue to have access to the Black Sea and will have the presence of Poles and Americans exploiting rare earths and agriculture. It will be an extension of Poland politically, economically and ultimately militarily. The Orthodox men who did not die in the war or migrated abroad will be much weaker and this will make the new Ukraine more cohesive socially and politically.
For Russia, the agreement will be good for the economy, but it will not be a complete victory because the existence of a new cohesive Ukraine linked to Poland and the US will be an unneutralized threat.
For China, the result is also mixed. A Russian agreement with the US means that Russia is also open to negotiations with the US and will put its interests first. So on the one hand it will be good for China's economy, but on the other hand it will also have to deal with the reality of Russia being open to negotiations with the US. Therefore the Chinese will also have to negotiate with the Russians for better agreements and security.
For the US, the outcome of the war in Ukraine will be equally mixed. On the one hand, they prevented a complete Russian victory and reasserted their control over Europe, but on the other hand, they saw that they had reached their limit and were also unable to defeat Russia. It was a stalemate in the grand scheme of things.
All this just shows that we are in a multipolar world again.
The fierce expansion of US hegemonic power after the collapse of the USSR is over, but they continue to be a superpower.
The US, China and Russia have seen their strengths and their limits and will have to coexist from now on. The balance of interests between the powers will once again be the focus of the world.
