Your take is based on fundamental flaw.
Russia wasn’t defeated in the Cold War but was convinced that the command economy is disadvantageous in terms of meeting the requirements of provision of the high living standards to its population and better results could be achieved through integration into Western institutions. Dissolving the Warsaw Pact and demilitarization was seen as a way of rapproachment.
The following events proved that they were naive as it was used by the West against Russia.
It is the primary reason why this trick is not going to work again.
Your take on the effects of the Ukrainian war on Russia is way off. It has reinforced the conviction of the Russian population that the West is the enemy.
The rest is history.
The other thing the sanctions have done is to implement cutoffs from various dependencies on the West that Putin wanted to do but thought would be too unpopular.
Is that why they have given people LED flashlights to find their way to the outhouse at night?
