This book is about the "plague of the 20th century", the Nazi Third Reich's quest for world domination. Having existed for only twelve years - from 1933 to May 1945 - the Third Reich, however, left behind many great mysteries and incomprehensible mysteries, most of which have not been solved and solved to this day. Post-war generations know little about the gigantic military might, sophisticated cunning, and utter ruthlessness of Nazism, which the USSR and its Western allies defeated in a bloody war in the mid-twentieth century: the most terrible war in human history, which claimed the lives of hundreds of millions. The uniqueness of this book is that the author, based on declassified archival documents, materials from the foreign press and his own research, fascinatingly tells about the sinister secrets of the "Black Order" of the SS, the secrets of the invisible war of intelligence and counterintelligence, the bloody and cynical struggle for power in the Third Reich and the unique technological breakthroughs and scientific discoveries of German scientists, which literally opened a direct path to the 21st century and even further into the future.
