This dissertation aims at offering a critical reading on the militarized (in)security performances that constitute the war on drugs in Latin America. We understand the war on drugs as a cluster of norms, policies and knowledge related to the control, via prohibition, of illicit drugs that prioritizes militarized strategies in their attempts to inhibit the production and commercialization of such substances at the supply side and that operates primarily through bilateral or multilateral cooperation with state agencies and political actors from the United States. We locate our discussion within the wider context of feminist/gender, poststructural and post-colonial studies, focusing on the process of construction the social world through (discursive and non discursive) (in)security performances. Our primary research strategy (among others) consists on discourse analysis, in order to look at the main discursive practices of the war on drugs that posit themselves as the official discourses of the United States as a state. We argue that the militarized performances of the war on drugs are rendered possible by a political imaginary on international relations that constructs the modern nation state as the primordial subject of world politics through the reproduction of borders of (in)security. Moreover, this process reveals complex power hierarchies and dynamics that are also informed by gender performances - being those the fluid duality between femininities and masculinities or the contraposition between a hegemonic masculinity and subaltern masculinities and femininities . In this sense, the war on drugs becomes possible by the same political imaginary that it (re)produces: one that (re)affirms the borders of possibility of (inter)national politics.
