Doomsday Men offers a sobering look at the cultural, political and scientific factors influencing the development of superweapons in the 20th century. Smith brilliantly shows how the literary creations of H. G. Wells and others, in works such a "The World Set Free," inspired nuclear scientists to pursue the development of weapons so utterly destructive that they were meant never to be be used. Yet they were, twice, in Hiroshima and Nagasaki, much to the horror of scientists such as Szilard and Einstein who advocated the development of atomic bombs only for preventing the Nazis from gaining a monopoly on the dreadful secret. Instead of the utopias imagined by Wells and the world government advocated by Einstein, the world launched into a sinister Cold War and a continued arms race, which has led, even until the present, to a diversion of needed resources into the development and maintenance of expensive and horrifically lethal armaments. Smith's book is a meticulously researched tour-de-force that offers readers an important glimpse into the rationale behind the creation of the world's nuclear arsenal, as well as a splendid examination of how culture and science interact. All in all, a highly worthwhile read.
