Recently, the state of the United States-Mexico border has assumed primary importance in American domestic politics. And with that, the border has been conflated with notions of security. This paper will investigate the root causes of the border’s securitization by grounding the case study of the Camarena Affair within The Copenhagen School’s burgeoning constructivist literature on securitization. The paper will conclude by discussing the legislative fallout from the Camarena Affair’s legacy, and arguing that the successful linkage between border and security occurred long before the events of September 11th, 2001.
