This article reviews six books! And it is a hard read, believe me. The subject is so vast, the human mind can hardly comprehend it
I will only copy the last paragraphs.
It is unrealistic:
to expect Russia to be the exception to the rule that empires, modern and ancient, do not go quietly. They either collapse as a result of crushing defeat (Germany, Japan) or domestic implosion (China), or they strive for decades to cling on to the scraps of their imperial past (Great Britain, France). Less than twenty-five years ago, Russia was the largest land empire in history.
One needn’t subscribe to the theory of Eurasian “complementarity” to grasp that, with decades or even centuries of cohabitation by Russia and its former imperial holdings, and without oceans or other natural borders to separate them (apart from the Caucasus), Russia is unlikely to go quietly anytime soon.
