The establishment of the landmark Joint Comprehensive Plan of Action (JCPOA) under the Obama administration, thought to be the start of a new chapter of US-Iran relations, was uprooted by the Trump administration almost immediately after the change in leadership. In order to understand how this radical policy shift is possible, this thesis analyses and compares the policy discourses on Iran of the Obama and Trump administration in terms of Self-Other identity construction. Taking a poststructuralist approach to policy discourse analysis, the ontological link between discursive identity and policy decision making is the central subject of study. The thesis concludes that the decisions to establish and withdraw from the JCPOA are constituted by discourses which in fact construct a highly similar radical Self-Other relationship between the US and Iran, within which the US is positioned as having to change the behaviour of the Iranian regime as arbiter of the Middle East and ally of the Iranian people. Crucially, they differ when it comes to the use of orientalist binaries, the capacity for change attributed to the Iranian regime (temporal identity) and the position of the US vis-a-vis the international community (ethical-spatial identity), which is congruent with the diverging policy decisions on the JCPOA.Show less
