This thesis aims to further and deepen the understanding of the American resistance to the support of Ukraine, a pressing and relevant issue, but to which none of the existing IR-theories has had a natural explanation. The thesis posits that ontological security studies can provide a meaningful addition to the partial understanding that the constructivist field of American identity studies can provide about the issue. The analysis does this by constructing a narrative from the statements of opponents of US support for Ukraine and then analysing this narrative through the lens of Ontological security, applying the concept of anxiety to help explain the mechanism through which narrative and action are co-constituted. The conclusion of the thesis is that introducing the dynamics of ontological security seeking through an application of the concept of anxiety allows for a furthering and deepening of the understanding of the American resistance to the support of Ukraine by illustrating the specific mechanism through which a narrative could be understood as guiding behavior.
