In response to the United States' renewal of the Iran Sanctions Act (ISA), President Hassan Rouhani ordered his top nuclear negotiators to take international measures and to begin developing a nuclear propulsion system used in “marine transportation.”
On Dec. 13, Iran’s official news agency IRNA published Rouhani’s separate letters to Foreign Minister Mohammad Javad Zarif and Ali Akbar Salehi, the head of Iran's Atomic Energy Organization. Rouhani ordered Zarif to “seriously implement the anticipated steps in the JCPOA [Joint Comprehensive Plan of Action] for addressing violations and required legal and international proceeding.”
