In this paper, we explore how (im)politeness and face are managed by two top diplomats of the US and Iran amidst
an ongoing conflict where both claim to occupy moral high grounds. To that end, 360 relevant tweets posted on the Iranian Foreign
Minister and US Secretary of State’s official accounts over one year were selected and analyzed qualitatively through the
theoretical lens of Culpeper’s (2011) impoliteness formulae and implicational
impoliteness framework. Three overarching pragmatic functions were identified: criticizing the adversary, giving directives, and
showing solidarity with allies while projecting a significant amount of face-threat to the adversary. We also identified three
main strategies that they used to justify their impoliteness, namely, appeal to the moral order, appeal to common sense, and
appeal to international conventions and regulations. These findings can contribute to impoliteness literature by providing
insights into the pragmatic functions and justifications in political communication, where the speakers have to balance their face
needs and their communicative goals.
