So you shouldn't be surprised if some countries aren't quite so trusting and naive about the West as you seem to think they should be.
One should base relations with other countries based on the evidence, not on what happened a century ago with people that are long gone.
At present, there is zero, ZERO, reasons for Russians to be worried about any sort of invasion or attack from the western side of there border.
Au contraire in fact. There was economic interdependence, what with all the gas imports etc.
No it's not.
You don't need to fear an
attack or
act of aggression from a
defensive alliance.
You only need to fear such an alliance if you yourself plan on attacking members of it.
It matters when the point of discussion is if they need to be worried about the border with that alliance.
It is exactly on-point, since the point of discussion is if Russia needs to be worried about being
attacked by NATO
NATO's raison d'être is DEFENSE in case of BEING attacked.
There is NOTHING in the treaty / manifesto which warrants any kind of attack / first strike. At all.
It is all about what happens when a member is attacked and nothing else.
Well, no...to be exact, there is also some stuff about criteria that must be fulfilled for a country to be able to become a member...
The point is, there is nothing there that would warrant any kind of attack / act of aggression.
In fact, suppose Ukraine was a member.
Suppose Ukraine mounts an attack on Russia as an act of aggression.
Suppose Russia then responds with a counter-attack.
This attack would not warrant an activation of article 5, because Ukraine would be the aggressor.
The treaty protects members against aggressors. It does not protect members that are the aggressors themselves.
