Since the increase in the Venezuelan migratory flow to Brazil in early 2017, Venezuelan mobility has been portrayed in the media and reproduced in the discourses of Brazilian government authorities both as a problem and a risk to be controlled and as an imperative for the reception and protection of this vulnerable population. Such representations and discourses were reinforced in March 2018 with the creation of the so-called Operation Acolhida, a government logistics operation constituted to manage the flow of the hundreds of thousands of Venezuelans entering the national borders. In order to question how the discourses of danger and border control coexist with a logic of reception and defense of human rights, the dissertation analyzes the discursive practices that participate in the construction of humanitarian governance of the Venezuelan migratory flow in Brazil, especially through Operation Acolhida. Starting from a post-structuralist discourse analysis, it is argued that Operation Acolhida, by articulating a specific logic of engagement with the Venezuelan other, functions (re) producing a specific representation of the Brazilian state and nation. As a practice of border and identity construction, Operation Acolhida presents itself, as David Campbell (1992) proposes, as a practice of foreign policy and border construction. From this perspective, the representation of state identity does not refer to an objective account of how the state really is - a dominant reading in Foreign Policy studies in Brazil, but rather as a representation of an unstable, provisional and continuously reformulated subjectivity. Thus, the dissertation contributes to think how the practices of representation of self and other, of inside and outside, of national and international articulated in Operation Acolhida, especially by its military actors, not only (re) produce what is the problem of Venezuelan refugees in Brazil - and how it should be managed - but also function by temporarily stabilizing an image - precarious and contested - of a benevolent, welcoming and friendly Brazil.
