SHORTLY after protesters took to the streets on Dec 28, Israeli Prime Minister Benjamin Netanyahu posted a video on his Facebook page wishing the Iranian people success in their noble quest for freedom. In Saudi Arabia, meanwhile, state-run media hailed the protesting Iranians with such joyful hysteria that Saudis could be forgiven for believing that the government in Tehran was on the verge of collapse.

Israel and Saudi Arabia have no formal diplomatic ties and decades of enmity behind them. However, their mutual pleasure over the grassroots demonstrations in Iran is the latest manifestation of a growing convergence of political interests, between the two Middle Eastern countries against their shared regional nemesis: Iran.

If the Saudi-Israeli rapprochement continues, their collaboration could lead to improved Israeli relations with other Arab states, removing Iran’s security buffer and possibly making Tehran more vulnerable to direct Israeli military action.

The first signs of the thaw between Saudi Arabia and Israel appeared in 2015, when both nations opposed the nuclear deal struck between Iran and the six world powers known as the P5+1. According to the terms of the deal, Tehran would cut back its nuclear programme in return for relief from economic sanctions.

To compensate for its nuclear concessions and concerned that Washington might not honour its commitment to the agreement, Iran followed its signing of the Joint Comprehensive Plan of Action (JCPOA) by intensifying the consolidation of its regional power base.

To that end, the Islamic Revolutionary Guards Corps (IRGC) and their overseas operations arm, the Quds Force, doubled down on their support for like-minded and mostly Shia paramilitary groups across the Middle East. In Syria, Iranian intervention in favour of Bashar al Assad, coupled with a relentless Russian air campaign against the rebels, finally turned the tide of civil war and kept Assad in power.

Tehran also took the opportunity to help oust extremist anti-Shia groups like the militant Islamic State (IS) from Syria. Iranian leaders insisted their intent was to nip terrorism in the bud, but their tacit goal was also and more importantly to maintain land access and supply lines to their main proxy, Lebanons Hezbollah, as part of Iran’s commitment to the axis of resistance and its strategic depth policy in the region.

The recapture of Aleppo by Syrian government forces in Dec 2016 relieved Iranian-backed militia forces stationed in northwestern Syria of a formidable battlefield challenge, enabling them to concentrate their manpower and firepower on the southwestern and eastern fronts.

This sounded alarm bells for the Israeli government, which feared entrenchment of Iran’s military foothold in its immediate neighbourhood.

Ali Akbar Velayati, a senior adviser to Iran’s Supreme Leader, has spoken figuratively of a resistance highway that starts in Tehran and continues through Mosul, Damascus and Beirut to the Mediterranean.

Similarly, with the expulsion of IS from Syria’s eastern province of Deir al Zor, IRGC-affiliated media outlets such as Mashregh News and Javan Online have promoted the establishment of a land corridor, linking Iran to the Mediterranean and potentially useful for military as well as trade purposes.

Israel’s response

Israel has responded to this perceived threat militarily and politically. On the military front, it has embarked on a sustained campaign of targeted air strikes against arms convoys believed to be delivering game-changing weapons to Hezbollah as well as a reported Iranian military base in Syria. On the political front, Israel has sought to build an anti-Iran coalition with the Arab bloc led by Saudi Arabia.

In an unprecedented Nov 16 interview with Elaph, the popular independent Arabic news site, Israel’s army chief of staff Lt Gen Gadi Eizenkot offered to cooperate with Saudi Arabia against Tehran, which he labelled the biggest threat in the Middle East.

“We are ready to exchange experiences with moderate Arab countries and to exchange intelligence to confront Iran,” he said, adding that in this matter there is complete agreement between the Jewish state and Saudi Arabia. Less than two months later, in a Dec 28 BBC interview, Israeli education minister Naftali Bennett echoed Eizenkot, explaining that Israel hoped to form coalitions with moderate Arabs in order to contain Iran.

Riyadh, too, has been cautiously building closer ties with Tel Aviv. In the summer of 2016, one year after Iran’s nuclear deal, an unofficial Saudi delegation, headed by retired general Anwar Eshki, met Israeli foreign ministry officials and Knesset members in an unusual visit to Jerusalem.

During the meeting, Eshki tried to persuade the Israelis to accept the Arab peace initiative, arguing that a two-state solution to the Israeli-Palestinian conflict would foil Iran’s attempts to exploit the Palestinian cause and delegitimise its support for anti-Israeli groups like Hamas, Islamic Jihad, and Hezbollah. Israel made no commitments, but welcomed the improvement of ties with Arab states.

The growth of Iranian power and influence in the region, however, is not the only driver of Saudi-Israeli entente. The Trump administration’s determination to counter Iran, along with Washington’s close relations with Saudi Arabia and Israel, have facilitated bilateral efforts to form such an alliance.

In November, Saudi Crown Prince Mohammed bin Salman summoned Palestinian leader Mahmud Abbas to Riyadh and presented him with the blueprint for a US-devised peace plan that favoured Israelis.

The powerful prince then demanded that Abbas either accept the scheme or resign. Tellingly, the Palestinian leader’s urgent trip to Riyadh came less than two weeks after Jared Kushner, President Trump’s son-in-law and adviser on the Middle East, visited the Saudi capital to discuss the plan with Mohammed bin Salman.

As delegates gathered in Davos this week, there were no official Saudi-Israel meetings reflected on the public programme. But Israeli Prime Minister Benjamin Netanyahu and top Saudi officials, including Foreign Minister Adel al Jubeir, are at the summit and have already made it clear that their governments view countering the threat from Iran as a primary foreign policy goal.

Iranian leaders are clearly worried about the emerging Saudi-Israeli alliance, which is likely to bring Riyadh’s Sunni allies, including the United Arab Emirates and Bahrain, into its fold as well. In a recent address to the Iranian parliament, President Hassan Rouhani declared that Iran would not resume its ties with Saudi Arabia unless Riyadh ended its friendship with Israel.

The new realpolitik of the Middle East means that Tehran may face even greater strategic challenges in the future.
