From Kotkin ‘ s biography of Stalin (released today):
Over the more than four centuries from the time of Ivan the Terrible, Russia expanded an average of fifty square miles per day.
I never considered it in this light but the statement explains a lot. Of course, the Russians can’t leave Ukraine alone. They have interiorized the need to expand as their only raison d’etre. And now they just can’t stop expanding.
P.S. So far I’m enjoying Kotkin’s book. The style reminds me of the way I explain this same material (Europe in the XIX th and early XXth century) to my Freshmen. Kotkin even uses my favorite rhetorical device of “if somebody were to fall asleep in 1900 and then woke up 30 years later, they wouldn’t recognize the world they’d encounter.”
