From the Russian perspective, they seem to view NATO encroachment into Ukraine as an existential threat to their survival. IMO they will not cease hostilities until their objective of de-militarising and de-nazifying Ukraine are complete.

On the other hand, the West continues to escalate the situation and doesn't appear to care about Russian motives whatsoever.

I don't see this ending any time soon; neither side appears to care for the motives of the other and so far show no signs of backing down.

Will the West ultimately accept a Ukrainian defeat if that's what it comes to, or if that's what it takes to avert nuclear holocaust?

What do you think?
