Nazi Germany, until the very last days of its existence, was developing an incredible military project - a “weapon of retaliation” of enormous power. It is generally accepted that this project was never implemented, that it was a cynical propaganda manipulation by Goebbels’ department. However, the famous researcher of historical mysteries Joseph Farrell is convinced that this is not so. The facts inexorably testify: German scientists were significantly ahead of the American ones in the development of a nuclear bomb, and the secret departments of the SS, which had inexhaustible reserves of “living experimental material” in the form of concentration camp prisoners, enthusiastically explored ancient knowledge, anti-scientific hypotheses and practical aspects of pseudoscience - and sometimes completely unexpectedly achieved amazing results. The monstrous “weapon of retaliation” was created and was not used during the fighting only by luck. Moreover, we are talking not just about a nuclear bomb, but about a weapon much more terrible than a nuclear one. Only this can convincingly explain the whole range of mysteries and inconsistencies relating to the last stage of the Second World War, over which historians and analysts have been puzzling for so many years.
