So it looks like Russia has said to the US that they are happy to negotiate a peace deal but they dont acknowledge any legitimacy in Zelensky. This looks to be a personal dig by Putin against Zelensky, who previously wrote into Ukrainian law that there would be no negotiation with Putin. Very Russian response indeed (tit for tat).
So the Russians and the US want "free" elections in Ukraine whatever that even means. As I understand things, Donald is in agreement, with his view being that Zelensky is part of the problem, not part of the solution. Zelensky for his part is playing the same role, which is in effect ostracizing him from the US. He seems not capable to adapt. Zelensky's days as a useful idiot appear to be over. Donald seems to not care who gets elected in Ukraine (which suggests a pro-russian or at the very least neutral government).
England is saying they can send troops to Ukraine but again, like Zelensky they look to be completely out of touch with reality. Russia has said a big no to Nato troops in any guise in Ukraine but are open to an international body (south american / asian / whatever). Most european leaders are floundering while they repeat the narrative of Russia invaded, russia to blame.
meanwhile the usual racists are spouting the same whiny cries about orc's (rolls eyes).
Seems to me the terms of a temporary ceasefire are outlined in your post:
Fighting stops, Ukraine holds an election. If Zelensky wins, he's legitimate, and Putin has to deal with him. Zelensky loses? Putin deals with the legitimate, and new leader of Ukraine.
Honestly, that sounds incredibly reasonable to me, given that Ukraine is dealing from a position of weakness.
