and yes it's real.

The best proof is the Ukraine, which was to play so frightful a role in the fate of the Russian Revolution. Ukrainian nationalism in Russia was something quite different from, let us say, Czechish, Polish or Finnish nationalism in that the former was a mere whim, a folly of a few dozen petty-bourgeois intellectuals without the slightest roots in the economic, political or psychological relationships of the country; it was without any historical tradition, since the Ukraine never formed a nation or government, was without any national culture, except for the reactionary-romantic poems of Shevschenko. It is exactly as if, one fine day, the people living in the Wasserkante should want to found a new Low-German (Plattdeutsche) nation and government! And this ridiculous pose of a few university professors and students was inflated into a political force by Lenin and his comrades through their doctrinaire agitation concerning the "right of self-determination including etc."

The Bolsheviks treated the Russian people as inexhaustible material for their social experiments. They dreamt of a world revolution that would wipe out national states. That is why they were so generous in drawing borders and bestowing territorial gifts. It is no longer important what exactly the idea of the Bolshevik leaders who were chopping the country into pieces was. We can disagree about minor details, background and logics behind certain decisions. One fact is crystal clear: Russia was robbed, indeed.

When working on this article, I relied on open-source documents that contain well-known facts rather than on some secret records. The leaders of modern Ukraine and their external ”patrons“ prefer to overlook these facts. They do not miss a chance, however, both inside the country and abroad, to condemn ”the crimes of the Soviet regime,“ listing among them events with which neither the CPSU, nor the USSR, let alone modern Russia, have anything to do. At the same time, the Bolsheviks' efforts to detach from Russia its historical territories are not considered a crime. And we know why: if they brought about the weakening of Russia, our ill-wishes are happy with that.
