TEHRAN, Iran — Turki al-Faisal Al Saud’s call for regime change in Tehran, let alone his mere participation at the July 9 Mujahedeen-e-Khalq’s (MEK) annual conference in Paris, is an unprecedented move against Iran by a high-ranking Saudi royal.

Prior to Faisal’s statements at the MEK convention, the Saudi deputy crown prince, Mohammed bin Salman, paid a 10-day visit that started on June 14 to Washington and then Paris, during which he stressed the necessity to counter the "Iranian threat.” Meanwhile, as has been the norm during his tenure so far, Saudi Foreign Minister Adel al-Jubeir, who accompanied Mohammed, went even further in his criticism of Iran's regional policy, demanding that Tehran stop “exporting its revolution.”

This situation has in fact been prevalent ever since King Salman bin Abdul-Aziz Al Saud was crowned in January 2015. As such, one can assume that there has been a paradigm shift in Riyadh's regional policy, which encompasses relations with Tehran. At this point, Saudi Arabia has crossed so many unwritten rules in its dealings with Iran that some observers anticipate a war between the two nations.

Yet despite all these changes, there are no parallels in Iran’s policy toward Saudi Arabia. Even with reference to the abovementioned developments, Iran did not bother to reciprocate — at least in terms of the level of its reaction. The question as to why it did not react has two logical answers. The first would be that Iran accepts the Saudi accusation that it is the main source of instability and terror in the region. However, given internal debates on regional policy in Tehran, this assumption has no basis. The second possible answer is that Iranian elites do not perceive the Saudi moves against Iran as being of importance, in terms of their effect. This answer is more relevant in Iran’s internal debates.
