Kourosh ZiabariAsia Times: Iran and Saudi Arabia are inching towards a rapprochement that, if achieved, would profoundly shift the region’s dynamics, diplomacy and stability. Officials from both sides have recently hailed backchannel talks held first in Iraq and now in Oman as “constructive.”

In May, Iraqi President Barham Salih confirmed his country had been hosting quiet talks between the two often bitter rivals. The talks, which started in April, have recently been attended by high-profile delegates, including Saudi chief of General Intelligence Directorate Khalid al-Humaidan and Iranian Deputy Secretary of the Supreme National Security Council Saeed Iravani.

The first symbolic breakthrough could be seen as early as next week. Iranian media have reported that Saudi Arabia has signaled it could send an envoy to attend President-elect Ebrahim Raisi’s inauguration scheduled for August 5. If so, the diplomatic overture would mark a significant departure since the two sides broke off diplomatic relations in 2016.

Raisi, in his first press conference as president-elect on June 21, said there were no barriers to the reopening of Iranian and Saudi Arabian embassies, and Iran was prepared to embrace normalized ties with its predominantly Sunni neighbor. Burying the past, of course, won’t be easy.

On January 2, 2016, an angry mob enraged by the Saudi kingdom’s decision to execute dissident Shia cleric Sheikh Nimr al-Nimr stormed the Saudi embassy in Tehran and its consulate in the city of Mashhad, ransacked the offices, set the diplomatic compounds on fire and caused other substantial damage.

Saudi authorities responded by freezing diplomatic ties with Iran and expelling Iranian diplomats. Although Iranian-Saudi relations have been marked perennially by rivalry for the upper hand in the Middle East and wider Muslim world, the embassy saga marked a new nadir in bilateral ties.

Iran never formally apologized over the embassy attack, even though President Hassan Rouhani decried the incident, saying in a message, “the action taken by a group of extremists in Tehran and Mashhad, causing damage to the embassy and consulate of Saudi Arabia, which should be religiously and legally in safety under the protection of the Islamic Republic of Iran, is by no means justifiable.”

Upon Rouhani’s instruction, the Ministry of Interior and Ministry of Intelligence opened investigations into the incident, and 40 people involved in the siege were eventually arrested. Yet, these gestures failed to pacify Saudi Arabia, which has long opposed Iran’s alleged interference in the affairs of Arab nations and its destabilizing role in the wider Persian Gulf.

The larger bilateral conflict was sparked when Saudi Arabia initiated a bombing campaign on Yemen in March 2015, where the Islamic Republic had been siding with and backing Houthi rebels opposed to the internationally recognized government of President Abd-Rabbu Mansour Hadi.

Houthis are a Zaydi Shiite minority that emerged as a resistance movement against the corruption of Yemen’s deposed President Ali Abdullah Saleh, who they believed plundered and stashed the resources of the impoverished Arab country to serve his inner circle and family, like the other Arab dictators in Egypt, Tunisia and Syria. They also resented the United States and Saudi Arabia’s sponsorship of the autocratic leader.

As the Arab Spring protests spread to Yemen in 2011, Houthis instigated an uprising against Saleh, causing him to resign in February 2012. Saleh’s deputy, Abd-Rabbu Mansour Hadi, took power, but Houthis were still disgruntled as they had no share of power.

They thus moved to expand their ties with Iran. Direct air traffic linking Tehran and Sanaa was launched, and Iran committed discounted oil to the insurgents, who in 2014 took control of the Yemeni capital, motivating Saudi Arabia to unleash airstrikes in support of the government.

The ongoing cataclysm in Yemen has been described as the worst humanitarian disaster worldwide, resulting in at least 130,000 fatalities. Meanwhile, a chronic famine has elevated the vulnerability of Yemen’s malnourished, destitute population in the time of Covid with no access to vaccines or reliable healthcare.

Saudi Arabia has so far refused to suspend its military operations, and Iran continues to supply drones, surface-to-air missiles, explosives and ammunition as well as financial aid to the Houthis, amounting to at least $10-15 million annually since 2010. The Yemeni question is the major fault line in Iran-Saudi Arabia relations, and the crisis will be a major roadblock to the normalization of ties.

Ali Bakir, an assistant professor at the Ibn Khaldon Center for Humanities and Social Sciences, Qatar University, says any prospective reconciliation between Iran and Saudi Arabia will require determination and commitment from both sides after years of debilitating proxy war.
