"The whole world believes that the two atomic bombs that crushed Japan in August 1945 were American made. In reality, as I would later learn, those bombs were Hitler's secret weapon. If I make this revelation today, it is not because I am seeking glory for Germany for having been first to liberate the forces that may one day soon destroy all of humanity. It is simply to establish a historical point."- Erwin K. Oppenheimer in "I'm Afraid!"In 1955, Charles Frémanger's Editions Jean Froissart in Paris, France published "J'ai Peur!" (I'm Afraid!), the purported autobiographical account of a German-turned-American atomic scientist. That work is presented here for the first time in English, with all the images featured in the original, with an index, and with a new preface that sheds light on this unique historic and literary contribution from the Cold War and the extraordinary European authors behind it."I'm Afraid!" is not just a moving portrait of human vulnerability, it is a work of extraordinary perception, even prescience. It lays out a succinct, readable history of the development of nuclear weapons, especially the moral and philosophical dilemmas they raise, while painting curious and compelling portraits of a gallery of historic personalities such as J. Robert Oppenheimer, Curtis LeMay, Wernher von Braun, Hermann Göring, Edward Teller, Gustav Hertz, and Adolf Hitler. The book's core themes are the weaponization of science, the fragility of human understanding, and the cataclysmic dangers of geopolitical conflicts in a thermonuclear era. In addition to its tantalizing historical claims about the origins of the atomic bomb, the book also addresses climate manipulation, potential new energy sources, and the necessity of a single global government to prevent a nuclear world war.
