The UNHCR promotes resettlement as an important protection tool to express solidarity with vulnerable refugees and countries of refuge. Yet, as resettlement is discretionary, its guiding principles and objectives are not binding and can be reinterpreted by states and supranational organizations. Against the background of UNHCR’s resettlement guidelines, this article examines the EU’s justifications of resettlement. Advancing theories of pragmatic sociology and based on an in-depth qualitative analysis, it teases out justifications of (1) humanitarianism, (2) border security, and (3) assimilability in EU discourses and policies. Revisiting EU policy advancements from the early 2000s until 2023, it shows that these justifications increasingly interlace and present resettlement as an instrument to protect refugees as well as EU borders and access to EU polities. The article argues for the need to understand the EU as a resettlement actor in its own right, with significant power to reshape resettlement as a protection tool.
