Again, all that matters is Russia believes NATO is an existential threat that is getting closer to their border. Good faith diplomacy has nothing to do with it.
Furthermore, Russia (and the USSR) has always used sticks rather than carrots in diplomacy. It’s not like they immediately went from friendly relations in Ukraine to boots on the ground. It was preceeded by their version of “diplomatic” bullying for years. You can see this now in many other countries.
To be clear, I’m not justifying their actions. I’m just saying you can’t look at their actions through a western diplomatic lens if you want to understand their behavior. They have a completely different modus operandi.
