From this book you will learn the true reason for the severe defeat of the Soviet troops at the beginning of the Great Patriotic War, which has nothing in common with the popular versions today. The author applies an original method of analysis, used only in Stalin’s personal intelligence, of recently declassified documents of the General Staff, GRU and SVR, special military historical literature, archival documents of the USSR, USA, Germany, Great Britain. For the first time in Russian historiography, the mechanism of almost deliberate setting up of Soviet troops for a catastrophic defeat is analyzed in detail, irrefutable facts are provided about the actual betrayal of the highest generals of the Red Army, and in some cases even about a pre-war conspiracy to surrender defensive lines to the Nazis. And of course, the book shows the true role of Stalin as an outstanding statesman, world-class politician, strategist, commander, diplomat and economic organizer of the Victory, who managed in an unprecedentedly short time to “melt down” a bloody catastrophe of unprecedented scale into the Great May 9, 1943.
