China, Cuba, Vietnam, the DPRK, and the Lao People’s Republic are still socialist, and greatly inspired the founding of socialist and communist parties in the rest of the world, including the West. All of those came as a result of the Russian revolutions (plural, because the February revolution set the stage for the October revolution).

Adding to the first comment, capitalism is also greatly shaped by it - the fear was so great that even in the aftermatch of the greatest war up to that date, basically all rivalling powers, no matter how exhausted, immediately banded together into containing the revolutions by all means including mass murder and military invasion.

And they continue that ever since. They will do everything to stop the revolution.
