Would the United States avoid the Red Scare?

Would the United States avoid the Red Scare if the communist revolution failed in Russia?

It would probably be much weaker because communism would lose its successful example and international momentum, though other American conflicts could persist.

The audience asks whether the United States avoids the Red Scare and related unrest. Fear of communist revolution must be separated from other American social and racial conflicts. A failed Bolshevik movement would reduce the prestige, momentum, and apparent global reach of communism and socialism. Major powers would have less reason to believe that a successful revolution could be repeated at home. Developments driven by distinct domestic causes remain less certain, so the answer is strongest on the communist scare rather than every form of unrest.
