A history of modern Russia. Kort begins by providing an overview of the historical background, he then begins with the establishment of the Bolshevik Dictatorship and then tells the story of Communist Russia before concluding with a section on the first 10 years of post-Soviet Russia.
The Soviet Colossus was just that: colossal. Since it dealt with a subject I don't really care for, it's hard for me to evaluate it fairly. I will say that I thought it dealt with communism and socialism very honestly. It bluntly portrayed the failings of each. It didn't sing the praises of any particular philosophy. It let you make up your own mind. It didn't sing the praises of any particular leader, either. It just presented the facts. So, while slightly dry and boring (make sure you have a slushy to slurp on while you're trying to read this), it gives a very good overview of the Soviet Union.
The book is informational and contains a wealth of data and research on its topic, but Kort's writing style can be dry at times. The book also sometimes leans into narrativization and broad generalization, such as geographic determinism, broad statements about the nature of Russia and Russians, and attempting to pull out historical patterns where none exist. At one point, he draws analogy between Eastern Slavs fighting the Mongols and Scythians fighting the Persians to imply a historical pattern of Russia defending "the West" from "Asiatic hordes." (Not his words, I should clarify, just the narrative he seems to perpetuate.) While Kort's research is extremely strong, I'm not sure the same can be said for the broad conclusions he comes to from that research.
Some parts of this book were interesting but it left me in the neutral zone on wheather it was good or not since 50% of the time, you were asking yoursef "Why did I pick this thing up?"
