Offramp?

I certainly get the point that you don't want to reward bad international behavior. But, as a purely pragmatic matter, I hope that Western countries are communicating suggestions to Zelenskiy for some sort of feasible offramp to offer the Russians in the negotiations which have now been agreed to. Putin has clearly badly miscalculated. But if some sort of face-saving offer of a way to defuse this crisis is not come up with, the ways forward all look pretty bleak. Exactly what that might be, I admit, I can barely imagine.
