LA SEGURIDAD INTERNACIONAL EN LA PROYECCIóN DE CHILE HACIA EL CONO SUR: ？DESDE LA DOCTRINA DE LA SEGURIDAD NACIONAL HACIA LA CONSTRUCCIóN DE COMUNIDADES DE SEGURIDAD O LA EMERGENCIA DE LA SECURITIZACIóN?
in this paper we suggest that the evolution of the international situation in the southern cone of america in the security field, from the mid-seventies, has been interpreted by the national security doctrine and, subsequently, by moderate constructivist approaches. in the early nineties, the latter began to receive more attention as way of addressing the regional challenges in a context of internationalization and democratization of the political entities in the region. this is reflected in the use of concepts as security communities and relational autonomy, as well as the contributions of human security approaches. however, we also emphasize a rethinking of the traditional perspectives with the relevance of the realist approaches, and those advanced by the securitization of some issues, in particular those regarding the threat building related to the instrumentalization of enduring disputes over borders.
