Saudi Arabia Reshapes Regional Alignments with Security Pivot to Israel and Egypt

Executive Summary

Saudi Arabia's hedging strategy toward the United States has reached its limits following the Houthis' seizure of the Bab el-Mandeb Strait and Washington's refusal to intervene directly. In response to President Trump's limited engagement, Crown Prince Mohammed bin Salman is diversifying the kingdom's security channels by accepting indirect intelligence support from Israel, coordinating with Egypt on Red Sea security, and signing a defense pact with Türkiye and Pakistan in Mecca. This shift should be viewed not as the victory of a specific axis but as a transitional multipolar structure where multiple security providers coexist. South Korean companies should factor in the risks to Red Sea shipping lanes as a constant cost and track the rise of Turkish, Pakistani, and Chinese competitors in the Saudi defense and infrastructure markets on a project-by-project basis. It is also necessary to separately monitor the political risks within the Islamic world that would arise if the security alignment between Israel and Saudi Arabia becomes official.

I. Situational Analysis

Saudi Arabia Reshapes Regional Alignments with Security Pivot to Israel and Egypt: A Situational Analysis

1. Background and Developments

The military balance in the Yemeni civil war shifted sharply in favor of the Houthi rebels after the first half of 2026. The Saudi-led reorganization of Yemeni government forces weakened internal cohesion by dismissing or ousting commanders from the Southern Transitional Council (STC)[11]. Exploiting this vacuum, the Houthis escalated their conflict with Saudi Arabia to its highest level since the 2022 ceasefire, immediately after two Iranian aircraft arrived in Houthi-controlled territory in July 2026[13].

The Houthis declared a naval blockade targeting Saudi Arabia and claimed attacks on three ships in the Red Sea. Saudi airports and oil infrastructure also became targets[13]. In response, Yemeni government forces struck the runway at Sana'a International Airport, and Riyadh retaliated with airstrikes on Houthi military and communication facilities on the Hodeidah coast[13]. This localized conflict quickly escalated. The Houthis launched a rapid military advance along the western coast, seizing the strategic port city of Mocha and the islands of Zuqar and Perim[1]. They ultimately brought the entire Bab el-Mandeb Strait and the strategic island of Mayun under their control[14].

Underlying these events is a structural distrust among Gulf states regarding U.S. security commitments. Following the U.S. shale revolution, the share of American crude oil imports from the Gulf fell from 25% in 2014 to approximately 8% in 2025[3][9]. With Washington's economic incentive to defend the Strait of Hormuz and the Bab el-Mandeb Strait diminished, a U.S.-Israeli airstrike on Iran occurred in February 2026, prompting Iran and its allied forces to resume missile attacks on Gulf oil-producing countries, including Saudi Arabia[3][9]. Amid these developments, Saudi Arabia, Türkiye, and Pakistan signed a mutual defense pact in Mecca on August 7, containing a clause similar to NATO's Article 5[2][5][9].

2. Current Situation

As the Houthis intensified their missile and drone offensive, alerts were issued in key Saudi cities, including Mecca, Taif, and Jeddah. According to local working-level officials, Saudi Arabia's hedging strategy toward Iran and the Houthis has reached its limits[10]. Saudi Arabia requested direct U.S. military intervention, but Washington refused. Crown Prince Mohammed bin Salman attempted to call President Trump twice on September 10, but according to U.S. officials, the White House offered only intelligence sharing and targeting support instead of direct intervention[14].

Amid this situation, the Jerusalem Post reported that Israel was providing intelligence support to Saudi Arabia for its anti-Houthi operations via U.S. Central Command (CENTCOM)[17][1]. This indirect request to Tel Aviv was first reported by Israeli media outlets Israel Hayom and the Jerusalem Post, while the Tehran Times framed it as “MBS pivots to Israel after catastrophic retreat in Yemen”[1]. From Iran's perspective, this event is being used as evidence of a substantive security alignment between Saudi Arabia and Israel.

Simultaneously, Saudi Arabia requested direct support from Egypt. Mohammed bin Salman visited Cairo and agreed with President Abdel Fattah el-Sisi to enhance coordination for protecting Red Sea shipping lanes[4]. President el-Sisi stated his support for Saudi Arabia's self-defense measures[4]. The visit took place days after Houthi missile and drone attacks struck Saudi cities and a separate drone attack forced Riyadh to temporarily shut down a key oil pipeline to the Red Sea[4]. The French-language outlet La Nouvelle Tribune reported on this with the headline, “Abandoned by Trump, MBS asks Israel and Egypt for help”[14]. Separately, Saudi Arabia is also reported to have requested air defense support deployments from France, the United Kingdom, Pakistan, and Egypt, as its interceptor missile stockpiles are being depleted[7]. The United States itself is facing a shortage of interceptor missiles due to its war with Iran[7].

3. Key Actors and Positions

Saudi Arabiais under dual pressure from the collapse of its proxy forces in Yemen and the Houthis' seizure of strategic locations in the Red Sea. The U.S. refusal to intervene militarily has substantially shaken Riyadh's confidence in the Washington-centric security umbrella[10][14]. Riyadh is simultaneously activating three safety nets: intelligence support from Israel, security coordination with Egypt in the Red Sea, and the Mecca pact with Türkiye and Pakistan. However, this appears to be more of an ad hoc response to the rapid collapse of the Yemeni front than an integrated strategy.

Egypthas expressed political support for Saudi Arabia's request but remains noncommittal about actual military involvement[15]. Cairo shares Riyadh's interest in the Red Sea shipping lanes via the Suez Canal but has not stated an official position on joining the Mecca pact[3][6]. This suggests a cautious calculation of the potential repercussions of a direct conflict with the Houthis.

Israelofficially denies involvement, but there have been successive reports that effectively acknowledge its provision of intelligence support through U.S. Central Command[17][1]. A shared perception of the threat posed by Iran and the Houthis underpins this informal security cooperation with Saudi Arabia. However, without official diplomatic relations between the two countries, this cooperation is only visible through the United States as an intermediary.

Iranis using the current situation as evidence that its regional strategy is succeeding. The Tehran Times has framed Saudi Arabia's outreach to Israel as a “pivot following a catastrophic retreat,” highlighting the Houthis' military successes[1]. Evidence of close involvement by Iran's Islamic Revolutionary Guard Corps with the Houthis has also been confirmed by local Yemeni analytical organizations[8].

Türkiye and Pakistanhave entered into a collective defense commitment with Saudi Arabia through the Mecca pact, similar to NATO's Article 5[2][5], but their actual military involvement remains uncertain. Türkiye faces political constraints due to its dual alliance structure within NATO, while Pakistan is limited by its focus on India and its commitments to the IMF[6][9]. Pakistan is also playing a mediating role, conveying Riyadh's messages to Tehran and demanding a halt to Houthi attacks[12].

The United Stateshas refused Saudi Arabia's request for direct intervention, limiting its involvement to providing intelligence and targeting support[14]. This, combined with the structural shift of reduced U.S. dependence on Gulf oil since the shale revolution[3][9], is accelerating the decline in the credibility of Washington's regional security commitments.

4. Key Issues

The first issue is whether Saudi Arabia's multi-pronged security strategy is complementary or contradictory. The intelligence support from Israel and the Mecca pact centered on Islamic nations have different orientations. The former is predicated on U.S. mediation, while the latter presents itself as an alternative to U.S. security commitments. The fact that these two tracks are being pursued simultaneously suggests that Riyadh's strategic direction has not yet been finalized.

The second issue is the effectiveness of the Mecca pact. Attacks from Iran and the Houthis have actually intensified since the agreement was signed[6][9]. Given that the official text has not been released and the political-military coordination body is still in its early stages, it is more likely that the pact will serve as a symbolic signal rather than exert real deterrence[3][6][9].

The third issue is the structural implication of losing control over the Bab el-Mandeb Strait. The Houthis' seizure of this strait and Mayun Island directly affects the stability of the entire Red Sea-Suez shipping route[14]. This extends beyond a security concern for Saudi Arabia alone, touching upon the interests of Egypt, European nations, and Asian trading partners.

The fourth issue is the sustainability of the informal cooperation between Israel and Saudi Arabia. A structure where security cooperation precedes the normalization of official relations is vulnerable should U.S. willingness to mediate weaken. Iran is likely to continue exploiting this asymmetry as a theme in its propaganda[1].

II. In-Depth Analysis

Saudi Arabia Reshapes Regional Alignments with Security Pivot to Israel and Egypt: An In-Depth Analysis

1. Analysis of Root Causes

The current crisis was triggered by the United States' refusal to fulfill its security commitments. Crown Prince Mohammed bin Salman attempted to call President Trump twice on September 10. According to U.S. officials, the White House offered only intelligence sharing and targeting support instead of direct intervention[14]. This was not a one-time refusal. The share of U.S. crude oil imports from the Gulf fell from 25% in 2014 to approximately 8% in 2025[3][9]. The economic incentive for Washington to deploy military assets to defend the Strait of Hormuz and the Bab el-Mandeb Strait has structurally diminished.

This erosion of incentive was demonstrated during the Iran-Israel war. When Iran and its allied forces launched missiles at Gulf oil-producing countries, including Saudi Arabia, following the U.S.-Israeli airstrike on Iran in February 2026[3][9], Washington's response was limited. According to local observers, this experience led Saudi Arabia to conclude that the U.S. security umbrella, while existing in name, does not function in a real-world conflict[10].

A second cause is the depletion of Saudi Arabia's own military capabilities. Facing a shortage of missile interceptor stockpiles, Saudi Arabia requested air defense support from France, the United Kingdom, Pakistan, and Egypt[7]. The United States, its primary arms supplier, had itself depleted its interceptor stockpiles in the war against Iran[7]. This case exposed the vulnerability of Saudi Arabia's security structure, which had relied on a single supply chain.

A third cause is the failure to manage proxy forces within Yemen. The Saudi-led reorganization of Yemeni government forces weakened internal cohesion by dismissing and ousting commanders from the Southern Transitional Council (STC)[11]. The Houthis exploited this vacuum. Immediately after two Iranian aircraft arrived in Houthi-controlled territory in July 2026, the level of conflict surged to its highest point since the 2022 ceasefire[13]. Without the internal collapse of the proxy forces, it is unlikely that the Houthis' advance along the western coast and their seizure of the Bab el-Mandeb Strait would have occurred at its current pace.

2. Structural Context

Security Structure: The Exhaustion of a Hedging Strategy

For a long time, the cornerstone of Saudi foreign policy has been hedging: maintaining alignment with its primary ally, the United States, while also engaging diplomatically with adversaries[10]. This strategy requires two conditions to hold. First, there must be confidence that the United States remains the ultimate backstop. Second, adversaries must refrain from substantive military action that goes beyond creating negotiating leverage. With the continuation of attacks by Iran and the Houthis and Washington's refusal to intervene directly, both conditions have collapsed simultaneously[10]. Saudi Arabia's move to diversify its security partners to include Israel and Egypt is more of an ad hoc measure to manage the failure of its hedging strategy.

Political Structure: Standing in the Islamic World vs. National Survival

For Saudi Arabia, public exposure of its security cooperation with Israel is a political liability. Given its identity as the custodian of Mecca and Medina and Arab public opinion on the Palestinian issue, cooperation with Israel must take an indirect form, routed through U.S. Central Command rather than direct channels[1][17]. The fact that the Iranian outlet Tehran Times immediately reported this with the frame “MBS pivots to Israel after catastrophic retreat in Yemen”[1] carries the political implication that this indirect channel itself can damage Saudi Arabia's leadership narrative within the Islamic world.

The simultaneous strengthening of cooperation with Egypt, Türkiye, and Pakistan represents an alternative path with relatively less political liability. Mohammed bin Salman visited Cairo to agree with President el-Sisi on coordinating the protection of Red Sea shipping lanes[4]. On August 7, Saudi Arabia, Türkiye, and Pakistan signed a mutual defense pact in Mecca containing a clause similar to NATO's Article 5[2][5][9]. As a collective defense framework within the Sunni Islamic world, this pact is a more politically palatable option than cooperation with Israel.

Economic Structure: The Dual Risk of the Red Sea and Hormuz

The vulnerability of the Saudi economy lies in the concentration of its energy export routes in two choke points. The Strait of Hormuz is under direct threat from Iran, while the Bab el-Mandeb Strait and the Red Sea have fallen under the effective control of the Houthis[14]. The Houthis have seized the entire Bab el-Mandeb Strait, including Mayun Island[14]. Saudi Arabia was even forced to temporarily shut down a key oil pipeline to the Red Sea due to a drone attack[4]. A situation where both routes are threatened simultaneously severely limits Saudi Arabia's ability to secure alternative crude oil export routes. This demonstrates that cooperation with Egypt (which controls the Suez Canal and the Red Sea coast) is not merely a diplomatic gesture but a matter of tangible economic security.

3. Historical Precedents and Comparative Cases

The History of the Arab League's Structural Failures in Collective Security

Attempts at regional multilateral security systems have a poor track record of success. The Arab League has intervened in only a quarter of all regional conflicts, with a success rate of just 20%[6]. There have only been three instances in its history where the Arab League's collective security measures led to actual action: the 1962–1967 Yemeni civil war, the response to Iraq's threat to Kuwait in 1961, and the response to Iraq's invasion of Kuwait in 1990[6]. It is too early to predict whether the Mecca mutual defense pact will break this historical pattern. A previous EAI analysis assessed that the pact is "most likely to function as a symbolic deterrent signal for the time being (55% probability), given that the official text has not been released and the political-military coordination body is in its nascent stages"[3].

Contrast with the 2019 Abqaiq Airstrike

The United States also refrained from a direct military response during the 2019 drone and missile attack on Saudi Arabia's Abqaiq and Khurais oil facilities. The current crisis is a repetition and intensification of that pattern. The difference is that at the time, Saudi Arabia had not completely given up its expectations of the United States. Today, the fact that Mohammed bin Salman immediately pivoted to the Israeli and Egyptian channels after being directly rebuffed in his call with President Trump[14] suggests that Saudi Arabia's expectations for a U.S.-centric, single-pillar security framework have structurally diminished.

Precedents for Gulf States Diversifying Arms Suppliers

Saudi Arabia's move to diversify its sources of air defense support to include France, the United Kingdom, Pakistan, and Egypt[7] is an extension of the ongoing trend of arms procurement diversification. The JoongAng Ilbo reported that Saudi Arabia is considering the "Chinese ballistic missile card"[15]. This is evidence that the Gulf states were already structurally aware of the risks of relying on a single supplier. The current crisis is acting as a catalyst, accelerating the pace of this diversification.

4. Key Variables Shaping Future Developments

First is the level of exposure of intelligence cooperation with Israel.Currently, it is maintained as an indirect channel via U.S. Central Command[1][17]. If this channel is upgraded to direct cooperation or if its media exposure increases, it could create political liabilities for Saudi Arabia's leadership narrative within the Islamic world and for its relations with its Mecca pact partners, Türkiye and Pakistan.

Second is whether Egypt will intervene militarily.President el-Sisi has so far limited his stance to expressing support for Saudi Arabia's self-defense measures[4]. However, the JoongAng Ilbo reported that Egypt is being pushed into a situation where it must weigh whether to enter the conflict[15]. If Egypt deploys its own military assets under the pretext of protecting the Suez Canal and Red Sea shipping lanes, it would open a path for a separate Saudi-Egyptian bilateral security axis to solidify outside the framework of the Mecca pact.

Third is the pace of Houthi military escalation.The Houthis have already seized control of the entire Bab el-Mandeb Strait, including Mocha and the islands of Zuqar, Perim, and Mayun [1][14]. If the Houthis leverage this control to effectively blockade Red Sea shipping lanes, it would directly impact not only Saudi Arabia but also Suez-related revenues for Egypt and Jordan. This could shift the pressure for regional realignment more strongly toward Egypt.

Fourth is the possibility of a U.S. policy shift.The speed at which Saudi Arabia builds an alternative security axis depends on whether the Trump administration maintains its current level of intelligence and targeting support or pivots to direct military asset deployment. If Washington adheres to its existing position, Saudi Arabia’s multi-pronged reliance on Israel, Egypt, Turkey, and Pakistan is likely to solidify from a temporary measure into a structural realignment.
