M. Research Institute of Culture of the Ministry of Culture of the RSFSR, 1991. - 256 s. In the summer of 1936, Trotsky completed the book What Is the USSR and Where Is It Going?, published in many countries under the title The Betrayed Revolution. This title itself points to the main theme of the book, which represented the result of many years of reflection on the fate of the victorious people's revolution, which resisted the onslaught of external and internal enemies, but betrayed from the inside by forces formally acting on its behalf. In "The Revolution Betrayed", the most difficult theoretical problems are presented in a clear and concise manner, which makes it accessible to the understanding of any educated person. This is a book, as I have rightly pointed out.... Deutscher, is Trotsky's most difficult work. Its perception requires dialectical thinking, rejecting flat, formally logical constructions and applying categorically complete definitions to characterize dynamic and incomplete historical processes.
