The unknown and classified KGB history of the largest country in Europe - Ukraine is the history of people, events, documents and files. The files have answers to many questions. The most important of which - why did a war begin again in Europe? Why is it so important for Russia to conquer Ukraine? Why are Ukrainians putting up such a powerful resistance? Historian Volodymyr Viatrovych, who declassified the secret archives of the Soviet special services from the Cheka to the KGB, talks about the history of Ukraine, the USSR and Eastern Europe from 1918 to 1991. The reader, is offered, along with various heroes and traitors, those who thought they were in control of events, and those who thought they had no power over them, to recreate the nearly century-old chess game between the Ukrainian liberation movement and the creators of the "prison of nations." Described in reports and recreated by a historian, this work looks at the cunning “special operations”, deadly moves, information wars and complex games among several players that are all an attempt to find an answer to the question: what creates our destiny - human will or circumstances?
