Ukraine has ended up the biggest loser. They have lost many people. Some died in the war while others have migrated to other countries and might never return. They might lose territories and mineral resources. Ukraine would have to depend on aid or loans to reconstruct their devastated country. I don't know if history will remember Volodymyr Zelensky as a hero or villain.
It's a terrible thing to convince US to sponsor the killing of young Ukrainians and Russians. Even if the fighters that are getting neutralized are not from the states, saving lives is crucial. Putin, after dealing with Ukraine soldiers, he found out it's not worth the effort, what's there to gain in fighting one another for years. However, Zelensky lost a lot of credibility the day he angrily left the Whitehouse, so he's probably not going to be a hero.
