The disagreement over the foreign policy between Zarif, seen as a moderate, and the hardliners in recent years has mainly revolved around two issues.
First, Zarif was the face of negotiations for what became the 2015 Joint Comprehensive Plan of Action (JCPOA), better known as the Iran nuclear deal. Zarif was heavily criticized by hardliners for being seen to make a unilateral commitment to the talks with the five permanent UN Security Council members plus Germany (the P5+1) without any proportional benefits for Iran.
After President Donald Trump’s withdrawal from the deal in May last year, the hardliners went further, threatening Zarif with impeachment in the parliament. Tehran decided to continue to comply with the JCPOA after the encouragement of the European Union, hopeful that Europe will help Iran overcome this phase of US sanctions.
But even this has been tested. At the very time when Iran and the EU were negotiating over future arrangements, news broke of two foiled terrorist attacks near Paris, with some European governments pointing the finger at Iran as the perpetrator. Iran’s ambassador to Germany at the time of these attempted terror attacks implied unknown elements in Iran might be responsible for trying to sabotage Iran-Europe relations. At home, Zarif was targeted for even more political pressure, especially given the European solution to the problem of US sanctions has so far proved to be timid and limited.
The second disagreement between Zarif and hardliners was over Iran’s engagement with intergovernmental anti-money laundering body, the Financial Action Task Force (FATF). In the past, due to its failure to comply with FATF guidelines, Iran’s name was included in the list of non-compliant countries. This changed in 2015 when Iran pledged to address FATF’s concerns. Rouhani’s government has sent four bills to the parliament to improve Iran’s grade in FATF and escape the blacklist, with a FATF deadline extended until February 2019.
Two of these bills passed the Iranian parliament, but two others (the Palermo Convention, and Combating the Financing of Terrorism CFT) were blocked in the Expediency Council. Rouhani’s administration and Zarif lobbied extensively to see the bills pass but they were faced with severe opposition by IRGC-backed hardliners that saw the bills a huge blow to their capabilities in the region.
In short, Zarif’s ambition for Iran to achieve global integration deeply contradicts IRGC and hardliners who pursue a hawkish anti-Western agenda.
