Russia's possibility of using nuclear weapons

This probability is close to zero.

The reason is not that Russia cares about humanity, nature and animals.

The reason is this: as soon as Russia hits several cities of the West with several nuclear weapons, the nuclear weapons of the West destroy many cities of Russia. He then invades Russia. Many parts of Russia also become independent. Putin also knew that NATO was stronger than Russia and he had expressed it. In this war, he can't get the help of the west like he did in the 2nd world war!

In short, I think that if Russia uses nuclear weapons, Russia will be destroyed. they know this and they cannot use nuclear weapons.
