From the very first stages of life, parents have provided their children with love and protection against harm from within or without, especially from life-threatening situations. Children's perception of death as a unique phenomena develops around age ten and later on, when they begin to grasp the meaning of mortality. This often occurs when they themselves suffer from terminal illness. Children have been the object of destruction, as witnessed by The Holocaust and Hiroshima. The threat of nuclear war poses a new problem for parents, since threatening others is no longer a viable solution to the conflict. In addition, adults manifest a massive denial that the destruction of mankind can take place at any time. This denial, like a family secret, prevents children from asking questions and expressing to their parents their fears about their own and mankind's destruction. Examples are given of how children do express their concerns and fears about the nuclear threat when they are allowed to express themselves. Unless this denial is replaced by open communication about the seriousness of the situation, children and adolescents will view the adults' denial as numbness and folly and as responsible for the world's destruction. A meaningful dialogue between parents and children about the threat is given as the solution to the family conflict.
