The broblems concerning the nuclear war crisis and the related organization can be divided into two groups. The first contains those which are found in such a critical situation that the nuclear war may break out in near future. The other is composed of those which are found after the actual outbreak of this type of war. As to the outburst of the nuclear war three possible cases (intended, escalation and accident) are often pointed out. The first group of the problems can be better understood by analyzing these cases with the international situation and the armaments conditions, both of which are always changing, for their background. In spite of the recent assertions of the contrary, it is emphasized that the second group cannot be sufficiently understood without scrutinizing the experiences of Hiroshima and Nagasaki, . Furthermore, a reflection on the past course of research into these experiences brings us much insight into the adequate way for organizing the scientific research effort when such social phenomena occur.
