The author starts from the idea that every war is determined by a fantasy presiding over the actions of men. This psychical reality is all the more true in that civil war, which has become a universal phenomenon, has its causality in the myth of the murder of the father. At this intersection between myth and fantasy, the adolescent finds himself back at the center of his Oedipal preoccupations. The war scene becomes for him the privileged place for enacting his aggressive and incestuous fantasies. A strategy that consists of dispensing with the symbolic castration, especially since the ideal father bursts onto the scene to compensate for the weakness of the real father.
