How many Soviet republics were there?

Alexey, have you ever wondered if "...spaceflight, peaceful atom..." could have existed even without the USSR? These are more the fruits of a certain mindset and the result of the often brilliant Russian mind, but not the merit of the existing system. And regarding "The Dog's Heart." Remember who wrote it and what the author wrote about, or rather, what he meant, and then, perhaps, you will wonder if it is worth being proud of the country in which you were born.
