This chapter attempts to apply the character-interlocutor-narrator voice model to the discourse of United States (US) administrations between 2003 and 2016. It also investigates the representation of the self and the other as well as the threat representation of the other. The data for the study are composed of key speeches given by Presidents George W Bush and Barack Obama while in office. The findings of the study shows that a shift can be detected in the administrations' approaches to representing identity and the relationship with the other that transforms from a conservative neo-realist worldview to a more interdependent liberal one. Additionally, a unique mediator voice emerges in the speeches of Barack Obama, characterized by the use of indexical demonstrative expressions.
