All those countries were protecting assets sent to Russia and Czechs abused by Bolsheviks. If they were actually _participated_ in civil war, Bolsheviks will be crushed in a week or so.
> Since all socialist revolutions are met with the full ferocity of the capitalist states, it's not clear how they can win militarily without becoming a dictatorship.
Yes, sure. "I'm not guilty, they've made me do it" - looks like favourite mantra for wrongdoers all over the world.
> No socialist revolution has succeeded in an industrialized nation. They have all taken place in the periphery.
Correlation doesn't imply causation. Many "peripheral" countries didn't have socialist revolutions and there were few attempts in industrialized nations. For example, Poland and Finland, having even lower industrialized level than Russian Empire - they were spared from socialist revolutions. Not that Bolsheviks didn't tried to instigate them.
> It sounds like socialism hasn't ever been achieved.
Ok, why you're still calling USSR, Venezuela, Cuba etc socialist countries then?
