I think the Minsk Agreements, negotiated in 2014 & 2015 provide a logical and reasonable place to start for peace.
It would be amazing if Russia would trust us again. I doubt that they will.
Since everyone but Russia lied about those agreements, used the time to ready Ukraine for war with Russia, then wrecked a potential peace in progress by sending Boris to shut it down
No wonder Russia calls us the empire of lies.
