Because the word “Soviet” was replaced by the word “Russia” that doesn’t mean the old Soviet modus operandi has fundamentally changed.
The ex-invaded Eastern European countries, including Ukraine, had been under Russian occupation for decades... they lived through hell under forced Russian/Soviet rule.
When the Soviet/Russian system momentarily collapsed, those previously occupied nations suddenly regained their freedom. But at that point they had no army to protect themselves in case Russia decided to occupy them AGAIN...
That’s why all previously occupied European eastern countries by Russia ran to NATO for urgent protection.
Without NATO, those eastern countries would already have been taken back by Russia. Proof : Ukraine wasn’t part of NATO - thus it was invaded by Russia!
The problem with the Soviet-Union or Russia is that since WWII they have always had a policy to colonize and expand into any country close to their borders. It continues today.
NATO is just trying to hinder further post WWII traditional Russian expansion. It’s the whole point of NATO. It’s a defensive organization.
Also :
What is often forgotten is that it is the CSTO that is helping Russias expansion policies. CSTO = Collective Security Treaty Organization. That is Russia’s own NATO equivalent. CSTO operates as an offensive organization.
So yes, it’s not only Russia attacking Ukraine right now, but the ENTIRE CSTO organization that is helping making this possible.

Their Dear Leader is a KGB guy. That takes some chutzpah to act like everything’s not that same crap.
