There was no Cold War defeat, at least the Russians don’t see it this way. They have mn’t seen NATO as military superior to themselves nor they see it as superior nowadays.
The Warsaw Pact and NATO were arguably "near peers."
Meanwhile, the Warsaw Pact has been thrown onto the scrap heap of history.
Deprived of its vassal states and buffer zones, the Soviet Union, by itself, was hopelessly outgunned, outflanked, and outnumbered by NATO.
Meanwhile, the Soviet Union has likewise been consigned to the scrap heap of history, while NATO has considerably grown in size and strength.
After more than 600 days of fighting, Russia's manpower and military assets have been significantly degraded by Putin's Special Military Operation in invasion of Ukraine. NATO has continued to grow, adding long-term hold-outs Finland and Sweden.
All signs point to Putin's Russia likewise soon following its predecessors on the scrap heap of history.
