You may be right with regard to further fragmentation.
Had the Germans won WWI the milirarism of the Kaiser would have been rewarded. You should know that the Nazi party was a product of the German Army's political manuvering and that the Lenin cell was conveyed into Russia by the German Army. Russia was a dead letter as a viable country.
Like Slavery Communism had to be allowed to expose itself through its evil deeds and impracticality.
Likewise, had the Bolshevik Revolution failed, as did similar uprisings in Hungary and Germany, tens of millions of human lives would have been spared. Tsarism was an oppressive system, to be sure, but it was benign in comparison with the butchery of Lenin, Stalin, and their henchmen. Moreover, Russian civilization and even the mental state of Russians were decimated by 70 years of oppression almost unparalleled in human history.
