This article seeks to identify the attitudes that the governments of Argentina, Brazil, Canada, Chile, the United States and Mexico have adopted toward the redefinition of the concept, and of the institutions of hemispheric security that are being developed in the Hemispheric Security Commission (HSC) of the Organization of American States (OAS). Based on the documents from the April 20-21, 1999, and March 20-21, 2000, sessions of the HSC, the article established the positions of these countries regarding five questions: their evaluation of the current state of security in the Americas; those phenomenon that each country considers to be a so-called "new threat," or "non-traditional threat" to hemispheric security; the proposals the countries make about the conceptualization of inter-american security; the evaluation and proposals of reform of the Inter-American Treaty of Reciprocal Assistance and the Inter-American Defense Board; and, the role that each country believes the OAS - specifically the HSC - in the process of redefining the Inter-American security system. Finally, the agreements and disagreements between these countries on these issues are analyzed.
