No, Russia needs to fuck off. Ukraine has repeatedly offered to negotiate. Ukraine are offering to be flexible but do have red lines. Russia on the other hand as offered nothing, just making unreasonable demands that would be suicide if Ukraine accepted the Russian terms. I you clearly do not know the history of past abuse of Ukraine by Russia, but the people of Ukraine do, and that is why they are fighting so hard. I learnt this when I was living in Ukraine for a while.
If the world can not afford continuation of this war then they should be offering Ukraine all the help they can.
