I don’t think revolutions are any more likely to be fascist than socialist, historically though genuine socialist revolutions tend to lose, mostly because international capitalism can play very nicely with fascism, but not socialism.

However if the U.S underwent genuine socialist revolutions, it’s an entirely different ballgame. The U.S has been the capitalist hand on the global stage for the better part of a century, constantly involved in overthrowing democratically elected governments in favor of fascist dictatorships.

With that constant capitalistic/fascistic pressure gone, and better-yet replaced with genuine socialism, you’d get a very interesting situation. You’d have genuine socialism in the U.S (probably followed by at least some socialist revolution or socialist-inspired reforms in Europe), and then rhetorical socialism in the east, marred by material capitalism. The contradictions of the global stage would intensify, and I don’t think there’s any Chinese theory for development in an internationally socialist stage.
