The reason why NATO has always been afraid of Russia is actually very simple. First of all, Russia has the most powerful nuclear arsenal in the world, none of which. Secondly, Russia is very big. For most European countries, Russia is still a behemoth. Finally, it is the Russian tough way of doing things and national character.

The first is the issue of Russia's nuclear arsenal. Russia's nuclear arsenal is the largest in the world, and there is none. If there is only one nuclear arsenal, of course, no one will be afraid, but in addition to the nuclear arsenal, Russia also has nuclear weapons delivery technologies such as supersonic strategic bombers, typhoon-class nuclear submarines and poplar M missiles. And the missile it developed is 27 times the speed of sound, and even the advanced technology of the United States can't intercept it. What's more, even though Russia's wallet is tight, it is still very luxurious in the maintenance and development of its nuclear arsenal.

Secondly, the volume of Russia. During the Soviet Union, this huge country was always the sword of Damocles hanging over all European countries. Today's Russia is close to western European countries, and its scale is extremely terrible for western European countries, and the flood of steel inherited from the Soviet era still scares them. Therefore, for western European countries, it is best to let Russia die completely, so as to reassure them.

Finally, the Russian way of doing things is very simple and rude. What if there is separatism? If you don't negotiate, you will fight until you dare not divide. For example, President Putin's famous saying: "10,000 verbal protests are not as good as the wings of a bomber." It is not difficult to see from these things what the Russian way of life is.
