What asymmetry are we talking about here? The Warsaw Pact disintegrated because it was held together by force by the Soviet Union and as that had ceased to exist, the Warsaw Pact had no reason to exist either (ask yourself if you think for example Poland would be in a military alliance with Russia if it could choose freely; the same for Czechoslovakia (invaded 1968-1991) and Hungary (1956)). Maybe if Russia sincerely tried to become part of the Western World, many things would look different now, buth we both know it did not.
> Western states chose to expand and entrench NATO
Well if the russians could once think about other peoples as having free agency it would help them immensely to get out of their eternal (and of course false) victim status. Why exactly do you think the Central European states jumped onto the chance to get into NATO as fast as possible? By whom are they feeling threatened? Of course since at least 2008 (Georgia) everyone knows the feeling was right and Russia will continue mass killings of their neigbours unless they meet a stronger enemy.
