I mean at this point it doesn't look like Russia wants to give anything back, but who knows. They need to start with a ceasefire and maybe over time they can figure out the rest.

They should have taken the deal from April last year, where Russia had reportedly agreed to go back to the pre-Feb-22 borders. And before that, they should have implemented Minsk actually. The most important things Russia wanted was for Ukraine to be neutral, and to stop attacking the Donbas.

Ukraine's negotiating position just keeps getting worse.
