Borders – both physical and otherwise – are seen to be on the rise, but in late modern warfare, a complex process of unbordering can be observed in drone warfare. Targeted killings through drone strikes have changed the battlespace, made physical occupation unnecessary and rendered the Westphalian border as contingent and arbitrary. Furthermore, drones perform a complex form of ordering without borders in unruly spaces imbued with uncertainty, violence and danger. This article examines the intersection of bordering, drones and ontological security through the CIA-led U.S. drone strikes in the Federally Administered Tribal Areas of northwest Pakistan. It examines the relationship between drone warfare and ontological security, specifically the effects produced by postcolonial unbordering and ordering. For the liberal state, drones provide a sense of ontological security and cohere with liberal values because they are deemed precise and ethical weapons that avoid collateral damage and protect military personnel, without the costs of occupation. Yet drone strikes create deep insecurity within postcolonial borderspaces, impacting communities already subject to multiple forms and legacies of power and control. This article argues that drone warfare has complex implications for bordering/unbordering practices in late modern warfare as well as hierarchical ontological insecurity in postcolonial and liberal subjects.
