Actually the reverse is the case. NATO has been expanding ever closer to the Russian heartland. Most of Russia’s industrial and agricultural potential is located in Western Eurasia. That’s the area that NATO is directly threatening.
The french invaded russia and lost, as did the germans. The mongols invaded russia and conquered. China is getting more and more aggressive and will need more resources and space to expand.
The russians can do as they please, defensewise, meanwhile the east is going to kill them.
While I have mixed feelings about NATO expansion, that organisation has not attacked russia.
