Relations between Iran and Saudi Arabia have been tense ever since the establishment of the Islamic Republic back in 1979. Initially, Iran’s doctrine of exporting its revolution and its leaders’ negative view of countries such as Saudi Arabia, together with Riyadh’s creation of the Gulf Cooperation Council and support for Iraqi dictator Saddam Hussein’s regime during its 1980-1988 war with Iran, led to mutual political pessimism. Ties were further strained in 1987 after the massacre of over 400 Iranian pilgrims by Saudi security forces in the holy city of Mecca. With the passing of Ayatollah Ruhollah Khomeini, the founder of the Islamic Republic, in 1989, followed by the pragmatic presidency of Ali Akbar Hashemi Rafsanjani, tensions began to ease — but were never fully eliminated.

In 2011, as the Arab Spring spread across the Middle East, the wall of mistrust between Tehran and Riyadh grew thicker. The civil wars in Syria and Yemen pushed the two sides into indirect military confrontations. Riyadh’s Jan. 2 execution of Shiite cleric Sheikh Nimr al-Nimr, amid Tehran’s protestations, brought the worsening tension to a head. Indeed, Saudi Arabia’s decision to cut ties with Iran after its diplomatic facilities were stormed by Iranian protesters, with countries such as Sudan, Somalia, Bahrain and Djibouti soon following suit, brought about a novel state in the Iranian-Saudi relationship. In this atmosphere, media pundits are asking whether it is possible that Tehran and Riyadh may enter direct military confrontation. The answer is clear: There will not be a war between Iran and Saudi Arabia, for five main reasons.

First, the administration of Iranian President Hassan Rouhani is pursuing a policy of constructive engagement with the world — which is what Iranians elected him for in 2013. In Iran’s complicated political system, the executive and legislative branches are elected by popular vote, though the Guardian Council’s vetting of candidates makes the elections process not entirely free. Within this political system, making a decision to engage in war is not an easy task. Therefore, while some Saudi leaders may beat the drums of escalation, the possibility of outright war depends on factors such as whether there is political will for such action and how the two countries choose to handle the crisis in their relations. In sum, engaging in war is not something that can be done by one side alone. Moreover, Iran’s government has no incentive to increase tensions, as evidenced by the condemnation of the attack on the Saudi Embassy in Tehran by the triangle of power in Iranian foreign policy, meaning Supreme Leader Ayatollah Ali Khamenei, Rouhani and Foreign Minister Mohammad Javad Zarif. In a goodwill effort, Iran has also announced that it will continue to send pilgrims to Saudi Arabia for the hajj this year. Thus, if Saudi Arabia intends to initiate war, the Iranian public — seeing themselves as victims of a violation — will mobilize, and also gain the sympathy of the international community.

Second, the majority of Iran’s current leaders were involved in the destructive war with Iraq and are fully aware of its costs. Rouhani held several military positions during the conflict, while Zarif and his deputies also remember the hardships of that era in their capacity as diplomats. Khamenei, who was president at that time, also served as chairman of the Supreme Defense Council, while Rafsanjani served as the de facto commander-in-chief of the Iranian military. Even Iran’s parliament speaker, Ali Larijani, served as a commander with the Islamic Revolutionary Guard Corps (IRGC). Larijani’s brothers, including incumbent judiciary chief Sadegh Larijani, were also involved in the conflict. Many other influential Iranian figures, including a great number of parliamentarians and Friday prayer leaders, also have bitter memories of war, some of them as war veterans. Moreover, although the IRGC at times seems to favor showdowns — such as in the cases of the recent detention of US sailors or its surveillance of the aircraft carrier USS Harry Truman in the Persian Gulf — it is not empowered to take arbitrary actions.
