>around why Russia might see it as a threat.

except that russia already has NATO neigbours.

Let us apply this logic to other countries. Maybe Poland or Lithuania are threatened but a Russian presence in Kaliningrad. So I guess maybe they too should stage a special operation to rid the area of Putin's Neo fascists?

The point is that this kind of thinking only considers Russia as an active agent, and everyone else is just some sort of NPC. It's extremely convenient that it aligns with Putin's propaganda of course
