NATO has never invaded Russia. If you're referring to World War ii, Germany has been almost the most pro-Russian member of NATO, has showing tremendous reluctance to provide any actual support, and had downgraded its military to be one of the smaller and weaker ones in Europe.
On top of that, Russia now possesses thousands of nuclear weapons that it obviously did not have when Germany invaded in 1941. That absolute deterrent is what protects Russia against invasion.
Who were the allies of Germany during the invasion of Russia? Italian divisions, the Spanish "Condor Legion," the Scandinavian SS Viking Division, Romanian divisions, the French SS Charlemagne Division, etc etc. (Bet you didn't know that, did you?)
So just possibly expand your tiny horizon and try to understand the Russian POV for confusing NATO today for Germany and Germany's allies, in the living memory of tens of millions of Russians. Not to mention the many more millions who lost fathers, uncles, etc to the German extermination invasion.
.
Not to mention many centuries of earlier invasions from Europe.
Americans have no frame of reference for repeated bloody invasions of extermination. We have oceans on both sides and weak neighbors top and bottom. Russians look at the world slightly differently, given their history.
If you can offer a comparable national experience in the American living memory, I'm all ears.
