Normally I don't like to throw around accusations of hidden racism, but whenever you've got the Communists and Wall Street on the same side, it's a pretty safe bet the story's got something to do with the Jews.
Rather than "hidden racism" its Anti-Semitism almost in plain sight. Of course the book ignores or smooths over countless details to meet the agenda it was clearly written for and anyone who puts most of the details espoused in this book in any context, or who knows anything about the Russian Civil War at all, realizes just how ridiculous the whole thing is.
