This article offers an analysis of the transnational discursive construction processes informing Latin American security governance in the aftermath of 9/11. It demonstrates that the Global War on Terror provided an opportunity for external and aligned local knowledge producers in the security establishments throughout the Americas to reframe Latin America's security problems through the promotion of a militarised security epistemology, and derived policies, centred on the region's ‘convergent threats’. In tracing the discursive repercussions of this epistemic reframing, the article shows that, by tapping into these discourses, military bureaucracies throughout the Americas were able to overcome their previous institutional marginalisation vis-à-vis civilian agencies. This development contributed to the renaissance of counter-insurgency and counter-terrorism discourses and policies in the region, allowing countries such as Colombia and Brazil to reposition themselves globally by exporting their military expertise for confronting post-9/11 threats beyond the region.
