The elephant in the room is NATO easterly creep, then seeing it as aggression when Russia decides on any maneuvering with its own border that is reactionary to the eastern creep. Address eastern creep and even pull back the external pressures from Russian borders and you’ll see there never was so called, Russian Aggression to begin with. The soviets lost more that all other countries combined in wwii, Russians are well aware of the horrors or war. I don’t believe they want to ever see that again.
