This is a proxy war between Russia and NATO, where the west is cynically using Ukrainians to fight for them. This was admitted by no lesser person than the US secretary of state. Furthermore, Russia doesn't need Europe, they were able to redirect their economy towards the global south, and it's becoming clear that Europe's obsession with defeating Russia is self destructive. Europeans allowed themselves to be cut off from cheap energy from Russia and Chinese markets that underpinned European prosperity. At the same time, the US is now preying in weakened Europe forcing it into unequal trade deals and to buy its expensive LNG.

So you agree that Russia can end this war by pulling back their armies from Ukraine territory.

Ukraine could end the war by accepting Russia's demands. Or the US and Europe could stop arming and funding Ukraine, that would also end the war. That would be a first step to mending the bridges they burned with Russia by starting a proxy war.

Why would Russia surrender when they are winning? Makes no sense. Losers don't get to dictate terms to the winner in a war.

The terms for peace are well known. They had already been agreed to by both sides during the Istanbul negotiations in 2022 before the British and the Americans went to tell their proxy to abandon negotiations and fight to the last Ukrainian instead.
