Drawing on the Strategic Culture Theory, this article analyzes Iran’s evolving ballistic missile program (BMP), by focusing especially on the period of the Trump administration (January 2017-January 2021), including both Iran’s Islamic Revolutionary Guard Corps (IRGC) shooting down a US surveillance drone in the Strait of Hormuz in June 2019 and Iran’s attack on the US military bases following the assassination of IRGC General Qasem Soleimani, in January 2020. This work demonstrates the increasing reliance on the ‘revolutionary’, more offensive narrative, which has become additionally reinforced after the assassination of General Qasem Soleimani and Professor Mohsen Fakhrizadeh. This has consolidated the retaliatory aspects in Iran’s foreign and security policy, while it has also marginalized moderated actors willing to engage in negotiations with the US.
