That is because the Stalin murdered the Trotskyists.

He knew, very clearly, along with Lennin and many others, that a state of perpetual, unending, international revolution would destroy basically everything. The Soviet Union had to be a bastion of Communism to then push outward. They had to build something.

The West is now infested with Trotskyists, Alinskists, and Bolshevists who demand that perpetual, unending, permanent revolution that destroys everything.

They are less like the Soviet Union, and more like the Khmer Rouge.
