While critical scholars have provided countless analyses of migration, its securitisation, and the practice of border security, they have tended to ignore tourism, its securitisation, and the practice of touristic security. Even rarer are critical studies that look at the relationship between these processes and practices. Using a Global North / Global South geopolitical framework, this paper (re)theorises migration and tourism as two-sides of the same neocolonial global matrix of power and, following, it links critical studies of the securitisation of migration and border security, with critical studies of the securitisation of tourism and touristic security. Focusing on the geopolitical relationship between the United States of America (USA) and Latin America, it shows how these two security practices are working together to fortify and secure—primarily white—US-American subjects, spaces, and mobilities and, in the process, how they are implicated in the fragilisation and insecuritisation of—primarily poor and black and/or brown—Latin American subjects, spaces, and mobilities. Through focusing on the relationship between migration and tourism, the paper identifies a self-sustaining neocolonial system of (in)fragilisation and (in)securitisation that powerfully underpins the contemporary global (im)mobility regime.
