Nitpicker.
Not at all. There is a vast difference between saying it was a Russian manual vs calling it by its correct title. The Russian people suffered most under the Communist regime.
It would be like instead of calling it the US Constitution you called it the constitution of England's North American colony. The czardom of Russia disappeared effectively upon the takeover by the communist Bolsheviks...murdered the czar and his family and millions of Russians too.
Hopefully you see what I mean...
