The article uses Rodolfo Walsh’s literary and journalistic work as a source to write a history about the rupture of nationalist feeling in Argentina between 1955 and 1977. It reviews the author’s literary production like one that is linked with three issues of Argentina’s history. First with the transformation of social context in that period because of ideological confrontation, second with the political fragmentation of the social bases, and last, with the establishment and radicalization of government repression. It proposes the category of tearing-of-identity like a useful tool to make a history about the feeling of subjective identity’s tearing with regarding the national identity. A situation that happens before open war declaration, and brings into play Nation-State stability.
