The use of armed drones has emerged as a principal counterterrorism tool for western militaries, especially France and the United States. While France submits its strikes to the United Nations for approval, the United States typically does not. Does this difference matter for public support and perceptions of legitimacy? To better understand these dynamics, we fielded original survey experiments across nationally representative samples in France and the United States totaling in over 1800 respondents. Our results reflect that international approval is associated with both higher public support and greater perceived legitimacy for a strike. Further, we find that respondents emphasize international law as the basis for support and legitimacy, suggesting a cross-national belief in multilateralism for normative rather than strictly instrumental reasons. These relationships are moderated by the identity of the country conducting a hypothetical strike, implying both an “othering” effect and the emergence of distinct models of strikes across countries that deserve more study amid the ongoing proliferation of armed drones.
