To go out of this situation is simple. It is basically for the Ukraine government to surrender and sheath their swords and allow peace to reign. The Zelensky led government is an agent of the US and are there to understand too. . I know it is achievable for the coubtbut difficult for the Ukrainian government because of the politics around this country. The coming of NATO to the Ukrainian government was the major issue affecting the citizens.
Surrender isn't an option. If you think that capitualtion of Ukraine will bring peace, you're very naive. Yeah, maybe for few years there will be peace. But most likely that it will be only matter of time until Russia will decide to take another part of Ukraine (or maybe whole) as they know that nobody will stop them.
At this moment it looks that most likely that war will end with some kind of peace negotiations. But at this moment nothing will not change until January when Trump will take his cabinet in White House.
