The widespread willingness to rely on thermonuclear bombs as the ultimate weapon displays a cavalier attitude toward death that has always puzzled me. My impression is that...most of the defenders of these weapons are not suitably horrified at the possibility of a war in which hundreds of millions of people would be killed...I suspect that an important factor may be belief in an afterlife, and that the proporttion of those who think that death is not the end is much higher among the partisans of the bomb than among its opponents.
