Which pretty much justifies Russia's assumption that NATO is not really a "defensive alliance" and an independent Ukraine joining NATO really is a serious threat to their security. Along with this:
Utter nonsense. When the Soviet Union broke up, the west gave Russia a complete do-over, wiping the slate clean, with an invitation to join the community of nations as a full partner. But they went with corrupt oligarchs and decided to appoint a new Czar for life, who then apparently decided he wanted their old territories back. No one wanted Russia as an enemy, until they started down the path of rebuilding their old Russian empire again by violent means.
They had a chance at redemption, and they decided to throw away their future on an old man's dream of reforming a long-dead empire. NATO is a absolutely a defensive alliance, however much Russian shills want to deny it. There is zero danger to Russia from NATO member states, and they damn well know it too, or their wouldn't have stripped their defenses along their borders to toss still more troops into the fires of the Ukraine war.
All Russia has done recently is to convince the world that they will never change their imperialistic spots. They're still stuck in an 18th century mindset of believing they deserve their old empire back - that "Russia has no borders."
