In the Middle East, the two most contiguous cultures are the Egyptian and Persian civilizations. For ages, they stood as beacons of durable learning and contributed immeasurably to human progress.

With the resurgence of “firstness” (i.e. America First), with all its ominous implications of narrow nationalism, there is a profound global need for a “dialogue of civilizations.” This call is not new, having originally been proposed by former reformist Iranian president Mohammad Khatami and most recently echoed by the Grand Imam of Cairo’s Al-Azhar in a speech before the German Bundestag in 2016.

However, while a broader conversation between the Islamic and Western civilizations is still of the utmost importance, so too is intra-Islamic dialogue. Egypt, with a third of the Sunni Arab world’s population, and Iran, the biggest Shia country, can be the prime movers for reconciliation in the Muslim world and for regional stability. Relations between the two regional powers originally soured in the aftermath of the Iranian revolution, when then-Egyptian leader Anwar Sadat gave refuge to the ousted Shah and signed the Egypt/Israel peace treaty in 1979.

Efforts to reconcile the two countries have been made in the past. In 2004, one of the authors, Mousavian, then head of the foreign relations committee of Iran’s National Security Council, was invited for a confidential meeting with Osama El-Baz, the then senior political advisor to then-Egyptian president Hosni Mubarak.

After a day of negotiations in Alexandria, a package was agreed for the normalization of Iranian-Egyptian ties. Ultimately, however, the agreement was met with rejection by top decision makers in both Cairo and Tehran.

Nevertheless, one of this article’s authors, Yassin El-Ayouty, assesses that if diplomacy were tried again, it would likely succeed. In a trip to Cairo in December last year, he found a groundswell within authoritative non-governmental organizations for Iranian-Egyptian rapprochement. The reasons for the warming up to Tehran are diverse and include cooperation on terrorism. Mousavian has also found readiness for such rapprochement in Tehran.

Despite fear-mongering by some in Egypt about a so-called “Shia menace,” El-Ayouty, through his present work on a book on the “Sunni-Shia split,” ​has found no religious foundation whatsoever for such a division.

Egyptian and Iranian Islamic scholars have in the past reached historic accords on bridging Shi’ism and Sunnism. In the late 19th century, Egyptian Sheikh Muhammad Abduh and Iranian cleric Jamal al-Din Asadabadi cooperated on creating a pan-Islamic movement. In the 20th century, Iranian Grand Ayatollah Seyed Hossein Borujerdi and Al-Azhar Grand Imam Mahmud Shaltut established cordial relations. Shaltut even issued a famous fatwa recognizing Shi’ism as a recognized Islamic sect. Al-Azhar had, for many years prior to that fatwa, taught Shi’ism as a part of its curriculum.

Unfortunately, in recent years, there has been an uptick in sectarian rhetoric from prominent Egyptian figures. Sheikh Yusuf al-Qaradawi, a prominent former Muslim Brotherhood acolyte, regularly engages in divisive bombast about Shi’ism and is a leading encourager of the some of the most reactionary elements in the Muslim world.

The late Iranian scholar, Hashemi Rafsanjani, once debated with Qaradawi after he had made controversial anti-Shia remarks. Qaradawi, however, is currently out of favor with Al-Azhar and living in Qatar as a Qatari citizen, a leading proselytizer of the puritanical and exclusivist Wahhabi sect.

In addition to the religious and political tensions between Cairo and Tehran, Egypt’s increased reliance on the Gulf Cooperation Council (GCC) countries – namely Saudi Arabia, Kuwait, and the UAE – has also served to lower the chances for Egyptian-Iranian rapprochement. The Egyptian economy has for years been sliding downward, a decline in fortunes due largely to a booming population (nearing 100 million). Interestingly, a top lifeline for Egypt has been loans from the UAE, which has covertly cooperated with Al-Azhar sheikhs against the Saudi Wahhabi sect.

Egypt’s hands-off stance in the war unleashed by Saddam Hussein on Iran (1980-1988) was reversed in favor of an inter-Arab collaboration to stop Saddam from swallowing up Kuwait (1990-1991). This was followed by an apprehensive wait and see regarding America’s 2003 war of choice on Iraq. The historic pendulum of Egyptian politics towards Persian Gulf issues can be seen as emblematic of Egyptian diplomacy’s aim to balance foreign relations.

Such desire to bifurcate Egyptian foreign policy makes the resumption of ties with Tehran a necessity. There are grounds to be optimistic about a future Cairo-Tehran rapprochement, as evident by the following facts:

1. The negative reaction of the GCC towards the Iran nuclear deal found no tangible expression of sympathy in Cairo;

2. The charges by America and some regional states about Iran’s fomenting terrorism or instability find no echoes in Cairo;

3. The Egyptian role in the so-called Arab coalition against Houthis in Yemen has been confined to safeguarding safe passage through the Gulf of Aden;

4. Iran’s role in support of the Syrian regime has now been directly bolstered by Cairo’s recognition of the folly of regime change in Damascus or anywhere;

5. Cairo’s relationship with Riyadh has its ups and downs. This is especially so in regard to rising opposition by Al-Azhar to the Wahhabi stranglehold on religious practices and education in the kingdom.

Egypt and Iran are the two most historically influential and leading civilizations of the Muslim world and indeed, humanity. Furthermore, any idea of a religious animosity between them today is grossly exaggerated. After all, it was the Shia Fatimid dynasty that constructed Cairo over a millennium ago.

Egypt and Iran are the respective powerhouses of the Sunni Arab and Shia worlds. Cooperation between them can play a critical role in managing regional conflict, alleviating Sunni-Shia sectarianism, and containing calamitous regional civil wars. Critically, Iran and Egypt also have principally a similar stance on terrorist groups such as ISIS and al- Qaeda. Therefore Cairo-Tehran have great historical responsibility to establish strategic cooperation to manage devastating crises in the region.
