I am not sure that is true. Most of the Western world was reeling from WW1 at that point in time. Lots of young men were removed from the labor force. Quickly there after the rest of the world went into the Great Depression. After that they were on to WW2. I am not sure there are any direct lines that can be drawn from Russian's overthrow of the Czars. There were just too many confounding things that were going on to make a claim that the rest of the world improved because of it. One thing we can say, and it was still my central thesis, is that the majority of those who most supported the over throw didn't benefit from it at all.
