It’s a historical inferiority complex/fear of a strong West. NATO is just a today’s name. You can trace from the Grand Duchy of Muscovy to now.
Well perhaps its time for Russia to grow up - other than Germany who invaded everybody they could, what western power has ever invaded Russia. Napoleon in 1812 but goodness that was two centuries ago. Russia is and has run been by paranoid tyrants Putin is just the latest tsar. The only country that desires Russian land is China. The Russians are like Muslims, nobody wants them in their neighborhood.
That history shows how Russia became the largest country in the world by “defensive” invasions. Somehow they have built a victim complex around it.
