I think the poster has some point though, in that it is not all Ukrainian factions that have been pushing for this, and was perhaps not them as much as western powers which prevented this concession (their policy is influenced by their more powerful neighbours and backers!)
In the present, the secretary general of NATO Jens Stoltenberg has said "Let me be clear: Ukraine’s rightful place is in the Euro-Atlantic family. Ukraine’s rightful place is in NATO. And over time, our support will help you make this possible."
I never "justified" Russia's actions.
