The website Asre Iran published an article by Ali Keidari analyzing the roots and future of the tension between Saudi Arabia and Iran. Under the headline “Saudi Arabia is an enemy of Iran,” he wrote that no one in Iran today has any positive thoughts about Saudi Arabia. Obviously, this feeling is mutual and most Saudis think negatively of Iran. The source of this mutual negativity, beyond the historical reasons, can be found in the broad-ranging disagreements between the countries on many regional issues. These disagreements have caused tension between the two countries and created a formidable wall of mistrust between them. The site then surveys the events following the Islamic revolution that led to the escalation of tension between the two countries. The starting point is the separation of Bahrain from Iran during reign of the Pahlavi dynasty. It then explores the root of the disputes, claiming that although many argue that these differences stem from regional rivalry between Iran and Saudi Arabia, the relationship between the two countries has long surpassed rivalry and become a conflict. For example, Saudi Arabia’s extensive efforts to boycott Iranian oil is more than rivalry; it can be considered a consciously hostile step, because of the importance of Iran’s oil exports. The lack of common interests between the two countries in many areas is worsening and increasing the divisions between them. For example, although Iran and Turkey have serious disagreements on various issues, such as the crisis in Syria, their common interests have prevented the relationship between Ankara and Tehran from becoming a conflict. But the story of Saudi Arabia and Iran is completely different. The only plausible resolution: Tehran wins and Riyadh looses or the other way around. The deep religious rift between Iran and Saudi Arabia (Shi‘ites versus Wahabis) is another significant factor in disputes. Although the root of the dispute cannot be attributed to foreign intervention, there is no doubt that the involvement of foreigners has played an important role in the relationship. The author argues that the state of the relationship between Iran and Saudi Arabia will continue to deteriorate. In his opinion, events in the region (the Arab Spring) are to the detriment of Saudi Arabia and its current role in the region, which far exceeds its real, logical weight. Apparently it will be reduced to its proper proportion as Egypt and Iraq return to the regional equations, but this will take time. It is further claimed that the Saudis are clearly interested in toppling the current regime in Syria but not because it desires democracy in Damascus! Rather it wants to topple Assad to compensate for the imbalance created with Iran after the fall of Mubarak. In any case, as long as the current upheaval and resistance in the Middle East remains, and stability is not achieved, the relationship between Tehran and Riyadh will not relax, until one of the parties waves a white flag.
