Houthi Escalation Against Saudi Arabia: Between Containment and Confrontation

Introduction

The Houthi movement’s military escalation against Saudi Arabia marks a major shift in the trajectory of the conflict in Yemen and in the relationship between the two sides, effectively ending the truce that had held since April 2022. The strikes on Abha airport (13 July) and on two oil tankers in the Red Sea (23 July)[1] were not simply a reaction to the 13 July strike on Sanaa airport aimed at preventing an Iranian Mahan Air aircraft from landing there — a strike Saudi Arabia denied responsibility for and which the Yemeni government claimed, saying it was intended to block the Iranian aircraft’s landing.[2] Rather, they revealed a Houthi strategy of launching a new phase aimed at securing economic and political gains and redrawing the rules of engagement at the regional level. The Houthis insisted on directing their response at Saudi Arabia after declaring a blockade against it, prompting the Saudi-led coalition to strike military positions on Kamaran Island and the Hodeidah coast on 24 July.[3]

The danger of this escalation lies in its move beyond the local, bilateral dimension with Saudi Arabia, becoming practically entangled with the US-Iran escalation in the Gulf and the Strait of Hormuz — turning the Red Sea and the Bab al-Mandab Strait into an auxiliary theater for the broader equation of regional tension and “mutual instrumentalization.” This is especially true following Saudi strikes on Iran-aligned Iraqi factions in response to attacks on oil facilities in the Eastern Province and Riyadh[4] — attacks the Houthis claimed responsibility for after a Saudi statement identified Iraq as their point of origin. Accordingly, the drivers and repercussions of this escalation are not confined to the Saudi-Yemeni bilateral track; they threaten regional security and global supply chains, and raise insurance costs and shipping times.

This situation assessment examines the contexts of the escalation, analyzes its drivers at the domestic and regional levels, and argues that the Houthis’ concentration of strikes against Saudi Arabia — accompanied by a relative neutralization of Yemen’s internal fronts — reflects a strategy of limited, calculated “brinkmanship” escalation aimed at extracting economic and political gains and integrating further into Iran’s axis of resistance, without sliding, at the current stage, into full-scale war.

Contexts of the Escalation

The escalation coincided with the US-Iran war and the continuation of Yemen’s “no war, no peace” condition. At the same time, the Houthi movement has faced internal pressures stemming from the suspension of salary payments, worsening living conditions, and tension in its relations with certain tribes.[5] It has also been unsettled by developments in eastern and southern Yemen this past January, which ended the Southern Transitional Council’s control there and strengthened the position of the Yemeni government — prompting the Houthis to declare general mobilization[6] and concentrate their escalation against Saudi Arabia.

Saudi Arabia, for its part, is contending with the fallout of the US-Iran war and attempts to drag it into that war through intermittent attacks targeting it. The Iranian flights and their cargo revealed coordinated Houthi-Iranian attempts to circumvent the security arrangements in place since 2015, without coordination with the Yemeni government or the Saudi-led international coalition supporting it — compounded by the supply of experts and military equipment to the Houthis, and Iranian statements threatening to close the Bab al-Mandab Strait.

The crisis began with the landing of an Iranian aircraft on 3 July, which the Houthi movement treated as a breaking of the blockade and the inauguration of resumed air travel. The aircraft carried a Houthi delegation to attend the funeral of former Iranian Supreme Leader Ali Khamenei, before the delegation returned aboard a second aircraft that landed at Hodeidah airport after being barred from landing at Sanaa. In an attempt to avoid escalation, the Yemeni government agreed to coordinate a Yemenia Airways flight to bring the delegation back, and — alongside Saudi Arabia — welcomed a Jordanian initiative to resume flights to Sanaa airport. Presidential Leadership Council chairman Rashad al-Alimi, however, described the Iranian flight as a violation of Yemeni sovereignty and of relevant UN Security Council resolutions.[7]

Reports carried by Reuters reinforced Yemeni government allegations of growing Iranian military support for the Houthis, reporting that Iran had sent Islamic Revolutionary Guard Corps commanders and advisers, along with missile- and drone-related equipment, to bolster the group’s ability to threaten navigation in the Red Sea.

Saudi Arabia, for its part, denied imposing a blockade on Yemen and denied responsibility for the strike on Sanaa airport, while affirming its right to take the measures necessary to protect its security and its vessels in accordance with international law.[8] Although Saudi Arabia did not respond militarily to the strike on Abha airport, the Houthis shifted the escalation to the Red Sea and the Bab al-Mandab Strait — in what appeared to be an attempt at mutual instrumentalization alongside Iran’s closure of the Strait of Hormuz, aimed at influencing regional and international policy, extracting political gains, and hastening an end to the US-Iran war. They declared they had struck two Saudi oil tankers as part of what they described as a “maritime blockade” of the Kingdom. This was followed by a strike on another Saudi vessel, before the coalition responded by bombing positions on Kamaran Island and the Hodeidah coast.[9] Despite the continuation of mediation channels, a statement from the UN envoy reflected the stalled prospects of earlier de-escalation efforts, warning that continued escalation could push Yemen toward a wider confrontation and deepen its entanglement in a turbulent regional environment.[10]

Houthi Motives: Exporting the Domestic Crisis and the Stakes of Regional Positioning

The Houthi movement’s motives arise from the interplay between its domestic calculations, as a sub-state armed actor, and the requirements of its regional positioning within what is known as the Iran-led “axis of resistance.”

Domestically, the group operates according to two levels of motivation. The first is compulsion-driven:

• Exporting internal crises outward and placing responsibility on Saudi Arabia. Through escalation, the group seeks to re-militarize society in the areas under its control and contain grievances and protests linked to the suspension of salaries, declining services, and worsening poverty. It also aims to secure economic gains that reinforce its control, by pressuring Saudi Arabia to influence the Yemeni government into accepting its demands regarding a share of state revenue.
• Weakening the Yemeni government and its allies. At a more ambitious level, the group is betting on weakening Saudi support for the Yemeni government and the components allied with it militarily and politically — reinforcing its own influence and improving its prospects for expanding its control in the future.

Regionally, this is expressed through:

• The group’s pursuit of entrenched recognition as a political and regional actor, using the threat to navigation as a pressure tool that compels states and shipping companies to engage with it to secure safe passage for their vessels — ultimately granting it political and economic leverage and gains.
• The group’s attempt to influence the course of the US-Iran war, within the framework of its commitments as part of the Iranian axis, by threatening energy sources and shipping lanes and raising the economic and political cost of the war’s continuation.

Regional Strategic Convergence and the Limits of Iranian Instrumentalization of the Houthis

Iran has a direct interest in escalation and in shifting the theater of conflict to the Red Sea and the Bab al-Mandab Strait, including threatening Saudi Arabia and alternative energy export routes. Iran’s role has been present since the earliest stages: Tehran invested early in building the group’s organizational, logistical, and military capabilities, with a moment such as the present one in mind, aimed at imposing new deterrence equations. This operational presence was reflected in the timing of the air bridge, and in the meetings held by Iran’s ambassador to the Houthi movement with the group’s deputy foreign minister on 5 July and with the head of its government on 11 July.

Reuters also cited three sources on 16 July as saying that Iran had asked the Houthi movement to prepare to close the Bab al-Mandab Strait should the United States strike Iran’s electricity grid infrastructure.[11] In the same context, Iran’s Tasnim news agency quoted the commander of the Islamic Revolutionary Guard Corps’ Quds Force, General Esmail Qaani, calling on Saudi Arabia to draw on what he described as “irrational and costly American policies” and to end the blockade of Yemen.[12] That such a statement came from a senior military commander reflects security messaging directed at Saudi Arabia. This coincided with the participation of Iran-aligned factions in Iraq in striking Saudi oil facilities — developments that, taken together, serve Iranian interests.

This convergence does not mean the two sides’ interests are fully aligned, nor that Houthi decision-making is wholly subordinate to Tehran; rather, it reflects a confluence of interests at this particular stage. Iran benefits from the group’s ability to threaten Bab al-Mandab and expand its deterrence reach, while the group uses regional escalation to improve its terms in the Yemeni file and in its relationship with Saudi Arabia.

Saudi Strategy: Containment and Building a Collective Deterrence Umbrella

Three main considerations have governed the Saudi response: protecting the objectives of Vision 2030, avoiding a return to full-scale war, and internationalizing the Houthi threat to international navigation. Accordingly, the Kingdom has combined a denial of imposing a blockade on Yemen with an assertion of its right to protect its security and its vessels, continued support for the Yemeni government, and calls on the international community to implement relevant UN Security Council resolutions — foremost among them Resolution 2216 on Yemen and Resolution 2722 on the security and freedom of navigation in the Red Sea.[13] The Security Council had condemned Houthi attacks on Red Sea shipping in January 2024.[14]

In parallel, Saudi Defense Minister Khalid bin Salman held talks with Turkish and American officials, before Saudi Arabia announced a move to form an international maritime coalition to protect waterways and confront threats to global navigation and trade.[15] Saudi Arabia relies on a policy of international coalition-building in addressing threats. This international alignment has provided Saudi Arabia with a deterrence umbrella that has allowed it to contain the escalation and distribute its costs, without resorting to a unilateral war against the Houthi movement. Yet internationalizing the confrontation remains a double-edged tool: it raises the cost of attacks for the group, but at the same time increases the likelihood that the confrontation becomes tied to, and expands into, a broader regional conflict.

The Yemeni Government: Between Containment and Preparing for Confrontation

The Yemeni government, in coordination with the Saudi-led coalition, has pursued two parallel tracks in response to the escalation. The first has involved attempting to avoid further escalation by offering alternatives to the Iranian flights, agreeing to some of the Houthi movement’s demands, and raising the level of military readiness in coordination with the Saudi-led coalition. Presidential Leadership Council chairman Rashad al-Alimi’s announcement of the resumption of oil exports at this particular time represented a political and economic move, aimed at activating state revenue and providing resources that would allow for the payment of salaries — after the Houthis had disrupted oil exports by striking the ports of Hadramawt and Shabwa in October 2022, strikes the group justified at the time by demanding that oil revenues be allocated to paying the salaries of employees in the areas under its control.[16]

On the second track, the Yemeni government — backed by the positions of allied components — declared its adherence to its sovereign rights and adopted a more hardline tone in its political rhetoric and military measures, affirming the readiness of the armed forces to fight to retake control of the capital, Sanaa, and the remaining areas, as a guaranteed pathway to achieving peace in the region. Presidential Leadership Council chairman Rashad al-Alimi also held meetings with the National Defense Council and with accredited ambassadors to rally international support and to convert the Houthi threat to international navigation into a geostrategic opportunity to re-enable the Yemeni government to impose its control over the entirety of Yemeni territory.

Scenarios

Scenario One: A Return to De-escalation (Medium probability)

This scenario assumes that regional and international efforts succeed in reviving earlier de-escalation understandings, supported by a response from the Yemeni government and the Saudi-led coalition to some of the Houthi movement’s demands under the roadmap — particularly the resumption of flights from Sanaa airport and the payment of salaries to employees in areas under the group’s control. These are steps the Yemeni government has previously shown willingness to accept, and others may be met as well, with negotiations on the remaining files continuing during the truce period.

This scenario rests on the continuation of mediation efforts and the parties’ recognition of the cost of sliding into a broader confrontation, alongside lessons drawn from earlier de-escalation experiences. Its prospects are further reinforced by indicators suggesting Saudi Arabia’s preference for a path of containment and de-escalation.

However, this scenario faces challenges, including the possibility that the Houthi movement raises the bar of its demands with every concession granted, as well as the fact that the de-escalation track remains tied to developments in the US-Iran war and their repercussions on the behavior of the various parties.

Scenario Two: Continued Partial Escalation (Most likely scenario)

This scenario assumes the continuation of limited and controlled military escalation, allowing the parties to secure political and military gains and improve their negotiating positions without sliding into full-scale confrontation. Its likelihood depends on how Saudi Arabia assesses the scale of the threat posed by this level of escalation and the nature of its response to it.

This path is considered the most likely, given the various parties’ recognition of the high cost of full-scale war, set against the political and military leverage that limited escalation provides — particularly amid the continuing influence of the US-Iran war on the calculations of regional actors. This scenario also explains the Houthi movement’s focus on targeting Saudi Arabia primarily, while keeping internal confrontations within Yemen at limited levels.

While this scenario is considered most likely at the current stage, it remains subject to change depending on the course of negotiations, and could constitute a transitional phase preceding either a return to de-escalation or a slide toward broader escalation, depending on developments inside Yemen, the level of Iranian influence over the Houthi movement, and the trajectory of the US-Iran war.

Scenario Three: Full-Scale War (Low probability)

This scenario assumes an expansion of the escalation to include repeated strikes on critical infrastructure and an expansion of ground confrontations, leading to the conflict’s transformation into open warfare — in the event that efforts to restore de-escalation fail and the parties come to believe their objectives can be achieved through the military option.

The likelihood of this scenario is tied to the collapse of negotiations, the ceiling of conditions the Houthi movement sets for halting its attacks, an increase in the levels of military escalation, developments in the US-Iran war, the parties’ capacity to strengthen their defensive and offensive systems, and the possibility of sudden developments that shift the balance of power.

Nonetheless, the prospects for this scenario remain limited, given indicators reflecting Saudi Arabia’s preference for avoiding involvement in a full-scale war, particularly alongside the ongoing US-Iran war and the attendant rise in military and economic costs, as well as the lack of clarity over the time required to achieve strategic objectives through this type of confrontation.

Conclusion

The Houthi movement’s motives for escalation intertwine domestic and regional considerations, making its behavior the product of an interaction between local pressures and regional-positioning calculations. On one hand, the group seeks to manage its internal challenges and consolidate its political and economic gains; on the other, it continues to play its role within the network of Iran-linked regional alliances.

By contrast, the Saudi approach rests on prioritizing the containment of escalation and avoiding renewed involvement in a broad military confrontation, while simultaneously affirming the protection of its national security, its continued support for the Yemeni government and people, and the preservation of navigational security in the Red Sea.

Accordingly, the scenarios for escalation remain open, shaped largely by the interaction between domestic variables and regional and international developments, and by the parties’ capacity to balance the costs of escalation against the gains of de-escalation. Nevertheless, continued partial escalation remains the most likely scenario in the near term: it provides the Houthis with a tool of pressure while allowing Saudi Arabia to build an international deterrence umbrella without resorting to unilateral war. This path, however, remains fragile, and could slide into broader confrontation should strikes on critical infrastructure recur, mediation fail, or Bab al-Mandab become directly instrumentalized within the US-Iran war.
