It was a military victory unless you exempt military action that does not involve shooting. Constant fail safe flights by nuke bombers, submarine patrols, a massive defense build up, strategic and tactical nuke placements blockades, airlifts, the militarization of space.
Russians do not admit defeat but they readily agree that the USSR was defeated. They see themselves as having shed communism.
There is still left over pro-USA sentiment but it is for the USA of the Reagan era and its carry on through Bush1. I try to explain to the Russians I meet that the Reagan USA is gone.
USSR was defeated by socialism in the first place. There was no incentives to make society any productive, every idiot understood it is the system to blame. Nobody wanted to work and at that period there was nothing to pay. Europeans rioted in the West and Muslims in the south tearing USSR apart.
It made a classic revolutionary situation by Lenin’s own book and Commies given up power without too much a fight.
I actually remember the end of communism in Russia. Apart from a few senile idiots and federal employees nobody wanted any part of socialism, and getting rid of costly empire was a good idea too.
