There is nothing here that would have been technically useful to a Russian bomb designer in 1950 or to an Iraqi bomb designer in 1990. But the primer contains much more than technical information. It conveys a powerful message that bomb designing is fun. The primer succeeds all too well in recreating the Los Alamos mystique, the picture of this brilliant group of city slickers suddenly dumped into the remotest corner of the Wild West and having the best time of their lives building bombs. It helps to perpetuate the myth.... This is what I mean by seduction-the myth, unfortunately containing an element of truth, that building bombs is a wild, consciousness-raising adventure.
