Concepts of the Security area, mainly used without care and criticism, are here submitted to reflection. Based on the adjective "multidimensional", I describe the form of how it has been introduced into the American debate of security under cover a "hemispheric security agenda". I criticize this attempt trying to deconstruct that concept analyzing briefly the threats like a perceptual phenomenon and reflecting philosophically on the different nature of "Security" and "Defense".
