“And what will Russia do if Ukraine accepts these propositions? What security guarantees does Ukraine get?”
Maybe the same guarantees as Russia got when they were promised that NATO would not expand if they agreed to a unified Germany in the 90s.
That worked out really well. Right?
Since Russia broke its word when they convinced Ukrainians to give up their nukes, perhaps the west should give them back. That way Ukrainians can guarantee their own safety.
