The paper utilizes the theory of neoclassical realism as its theoretical foundation to understand the relations between the Islamic Republic of Iran and countries of the Gulf Cooperation Council (GCC). An insight is provided into defining Rouhani’s foreign policy discourse and slogan, primarily towards the GCC, while addressing the significant shifts in the region, which implicated Iran’s Rouhani stance towards the GCC and its members. The paper concludes with how the recent developments of the Iranian elections and Ebrahim Raisi will impact the future of Iran-GCC relations. From an analytical standpoint, it was found that Rouhani had difficulty engaging with the GCC countries due to impediments by the Islamic Revolutionary Guard Corps (IRGC). Similarly, the article highlights Rouhani’s era in Iran’s foreign behavior towards the GCC while exploring whether he achieved his foreign ambitions and provided a vision for the significant challenges awaiting the Raisi presidency.
