It's highly revealing that Western spinelessness and cowardice (plus our usual stupidity and complacency) has resulted in a situation where Russia has learned a great many lessons that negate NATO's former strengths. As NATO continues to sit idly on its hands and do nothing at all, Russia is learning, adapting, and becoming a more significant threat. When Putin orders his invasion of the Baltic nations, NATO's out-of-date equipment and tactics will, along with the usual Western dithering and prevarication, result in an overwhelming Russian victory - in stark contrast to the debacle of Russia's attempt to storm Kyiv in early 2022.
Once again, our stupidity and complacency will have catastrophic consequences. The lessons of the 1930s have been forgotten by generations of waddling empty-heads for whom junk food and junk entertainment are the only "important" things in life.
