Failure to deal with the issue of collective and social loss increases the risk of extreme nationalism. When taken too far, a repetition of manic defence can arise that manifests itself in the form of war. In this paper, the notion of the “inability to mourn” by the German Psychoanalysts A. and M. Mitshcerlich (1967) is discussed in relation to the problem of Japan’s post World War II nationalism, and its silence on social matters. The process of confronting past atrocities committed by the state is then discussed from the perspective of structural theory.
