The Houthi–Saudi conflict is one of the most misunderstood struggles in the Middle East. It is often described as a proxy war in which Saudi Arabia represents one side and Iran directs the other. This interpretation captures an important dimension of the confrontation, but it fails to explain how the conflict began, why the Houthis gained domestic support, why Saudi Arabia intervened, and why years of military operations failed to deliver a lasting settlement.
The conflict has three interconnected dimensions. First, it is a Yemeni political and civil conflict rooted in the breakdown of the country’s transition after the 2011 Arab Spring. Second, it is a regional confrontation shaped by Saudi Arabia’s security concerns and Iran’s efforts to expand its strategic influence. Third, it is an international security crisis because Yemen sits near the Bab al Mandab Strait, a critical maritime passage linking the Red Sea with the Gulf of Aden.
These dimensions reinforce one another. Yemen’s internal divisions created opportunities for the Houthis to expand. Iranian assistance increased their military capabilities. Saudi intervention transformed the domestic conflict into a regional war. Cross border missile and drone attacks then made the conflict a direct security concern for Saudi Arabia, while attacks on commercial shipping extended its consequences to global trade.
The human consequences have been devastating. The UN Office for the Coordination of Humanitarian Affairs estimates that 22.3 million people in Yemen will require humanitarian assistance and protection during 2026, while 18.3 million face acute food insecurity. These figures demonstrate that the conflict is not merely a contest between governments and armed movements. It is also a prolonged crisis of survival for millions of civilians.
Understanding this war therefore requires a careful distinction between documented evidence, the claims made by the parties, and broader strategic interpretations. Iran’s support for the Houthis is real and significant, but the movement has its own history and political interests. Saudi Arabia had genuine security concerns, but its military intervention did not produce the political outcome it sought. Neither observation removes the responsibility of any party for unlawful attacks or civilian suffering.
1. Who are the Houthis, and where did they come from?
The Houthis, who call their movement Ansar Allah, emerged from northern Yemen, particularly Saada Governorate. The region has a long history associated with Zaydi Shia Islam, a tradition distinct from the Twelver Shia doctrine dominant in Iran.
The movement developed during the 1990s amid religious revival, political dissatisfaction and concerns about the marginalisation of northern communities. Its supporters objected to corruption, unequal development, the conduct of the central government and what they perceived as the growing influence of rival religious and political movements.
The group takes its common name from Hussein Badreddin al Houthi, a cleric and political figure who became a prominent opponent of President Ali Abdullah Saleh. Government forces killed Hussein al Houthi in 2004. His death helped transform a political and religious movement into an increasingly militarised rebellion.
The subsequent Saada wars deepened the hostility between the movement and the Yemeni state. Military confrontation strengthened the Houthis’ organisational experience, local networks and ability to mobilise supporters. The movement became more than a protest organisation: it developed an armed structure and leadership capable of challenging the government.
This history matters because the Houthis did not originate as an Iranian creation. Their roots predate their emergence as a major regional actor and lie within Yemen’s own political and social conditions.
That does not mean Iran played no role. Rather, the sequence matters: a locally rooted movement developed first, and its relationship with Iran subsequently became more significant as the regional confrontation intensified.
The Houthis also developed an ideological identity extending beyond Yemen. Their rhetoric frequently condemns the United States and Israel and presents the movement as part of a wider regional resistance camp. That messaging has helped them establish political connections with Iran and other groups opposed to American and Israeli influence.
Yet ideological alignment is not the same as complete operational control. The Houthis have their own leadership, domestic rivals, territorial objectives and calculations about survival. Their relationship with Iran is best understood as a strategic partnership with significant external assistance, rather than an assumption that every Houthi decision is dictated in Tehran.
2. How Yemen’s political transition collapsed
The immediate background to the present war lies in Yemen’s 2011 uprising.
For decades, Ali Abdullah Saleh had maintained power through a complicated system of patronage, alliances with tribal leaders, military networks and political bargaining. His government faced longstanding criticism over corruption, economic inequality, regional marginalisation and weak public services.
The Arab Spring protests intensified demands for political change. Saleh transferred power in 2012 under a transition arrangement supported by Gulf states, and his deputy, Abd Rabbu Mansour Hadi, became president.
The transition was supposed to create a more inclusive political system. A National Dialogue Conference brought political parties, regional representatives and other constituencies together to discuss the country’s future.
However, negotiations failed to resolve several fundamental questions.
Who would control the military? How would state revenue be distributed? What degree of autonomy would regions receive? How would southern separatist demands be addressed? What political position would the Houthis occupy? And how could a weak central government implement an agreement across a country with powerful local armed networks?
Disputes over federalism became particularly contentious. The Houthis opposed proposed arrangements they believed would leave their strongholds disadvantaged in terms of territory, resources and access to economic opportunities.
These disputes unfolded while the state remained fragile and Saleh retained considerable influence through military and political allies.
In 2014, public anger over fuel price increases and dissatisfaction with the transitional government created an opening for the Houthis. They advanced towards Sana’a and took control of the capital in September 2014, benefiting from cooperation with forces loyal to Saleh.
The alliance was remarkable because Saleh’s government had fought the Houthis for years. It was a tactical partnership based on shared short term interests, not a reconciliation of their previous conflict.
The takeover fundamentally weakened the political transition. An armed movement had gained control of the capital without an agreed national settlement, and the government’s authority deteriorated further.
Hadi eventually left Yemen and appealed for international support.
This was the point at which an internal political crisis became an internationalised war. According to the UN Department of Political and Peacebuilding Affairs, the Saudi led coalition intervened militarily on 26 March 2015 at Hadi’s request.
The central lesson is that the conflict did not begin as a simple confrontation between Saudi Arabia and Iran. Yemen’s internal political failure created the conditions in which external powers could intervene and pursue their own strategic interests.
3. Iran’s support for the Houthis: What is established?
Iranian support is one of the best documented aspects of the conflict, but the details need careful interpretation.
The United Nations Panel of Experts on Yemen has reported foreign assistance to Houthi forces and identified similarities between Houthi operated weapons and systems produced or used by Iran and associated networks.
A 2024 UN report noted that the Houthis would not have the capacity to independently develop and produce a wide range of complex weapons without foreign support. The systems discussed included ballistic and cruise missiles, one way attack drones, maritime radars and other sophisticated military equipment.
The Council on Foreign Relations, in an analysis updated on 10 April 2026, describes Iran as the Houthis’ primary external benefactor, providing security assistance including weapons transfers, training and intelligence support. It also notes that the relationship has strengthened the Houthis’ ability to project power beyond Yemen.
What does Iranian support provide?
Iranian assistance has several potential components.
Weapons and components. External supply networks can provide components, technical designs and systems that would be difficult for the Houthis to manufacture independently.
Technical expertise. Advanced missiles and drones require specialised knowledge of propulsion, guidance, communications and targeting. Technical assistance can help a movement assemble, maintain or modify weapons systems.
Training and military advice. Assistance may improve the organisation’s ability to plan attacks, operate complex systems and integrate different capabilities.
Strategic knowledge. Experience shared by regional partners can help the Houthis develop tactics against air defences and conduct operations over greater distances.
These forms of assistance are not interchangeable. Evidence of an Iranian designed component does not necessarily establish who ordered a specific attack. Evidence of weapons transfers does not automatically prove that Iranian officials exercise direct command over every operation.
The most defensible conclusion is that Iranian assistance has substantially increased Houthi military capabilities, particularly in missile, drone and maritime operations.
Why Iran supports the Houthis
For Tehran, the Houthis offer strategic influence near Saudi Arabia’s southern border and close to the Bab al Mandab Strait.
Iran does not need to deploy a conventional army into Yemen to create pressure on Saudi Arabia or complicate Western security planning. A capable armed partner can threaten military installations, energy infrastructure and commercial shipping while requiring a much smaller direct Iranian commitment.
The relationship also fits Iran’s broader strategy of building partnerships with regional armed movements that share some of its strategic objectives. These relationships can create multiple points of pressure against rivals and complicate the calculations of Saudi Arabia, Israel and the United States.
But the alliance is not identical to Iran’s relationship with every other member of its regional network. The Houthis have their own history, religious tradition and domestic interests. Their cooperation with Tehran does not eliminate their independent agency.
Are the Houthis an Iranian proxy?
The answer depends on what the term means.
If “proxy” means an armed movement that receives Iranian assistance and whose actions can advance Iranian strategic interests, the description captures part of the relationship.
If it means an organisation entirely controlled by Iran, with no independent political agenda, it becomes misleading.
The Houthis existed before their relationship with Iran became as important as it is today. Their leaders make decisions about Yemeni territory, domestic opponents, political control and revenue. They may cooperate with Iran while still pursuing objectives shaped by their own interests.
A balanced assessment therefore recognises both realities: Iran has helped make the Houthis a more capable regional military actor, but the conflict cannot be explained by Iranian influence alone.
4. Why Saudi Arabia intervened
Saudi Arabia’s intervention was shaped by security concerns, regional competition and the desire to preserve the recognised Yemeni government.
Fear of Iranian influence
Saudi leaders viewed the Houthi takeover of Sana’a as a major strategic setback. Yemen shares a long border with Saudi Arabia, and an armed movement hostile to Riyadh could threaten border communities and strategic infrastructure.
The prospect of an Iran aligned movement consolidating power in Yemen also raised fears that Tehran would gain another position from which to pressure Saudi Arabia.
Those concerns became more concrete as the Houthis developed and used missiles and drones capable of reaching targets inside Saudi territory.
However, the strength of Saudi Arabia’s threat perception should be distinguished from the question of Iranian operational control. Riyadh had reasons to be concerned about the Houthis’ capabilities and alignment even if Iran did not directly command every Houthi operation.
Supporting the internationally recognised government
Saudi Arabia and its coalition partners argued that the intervention was intended to restore the recognised government and reverse the Houthi advance.
This argument reflected the international recognition of Hadi’s government and the concern that a political transition could be overturned by force.
Critics, however, questioned whether an air campaign could restore political legitimacy or rebuild institutions that had already been weakened by years of corruption, rivalry and poor governance.
A government can be internationally recognised while facing serious domestic weaknesses. Likewise, an armed movement’s territorial control does not automatically establish a democratic mandate.
Yemen needed a political settlement that could address both international recognition and domestic legitimacy. Military intervention alone could not resolve that dilemma.
Regional credibility and deterrence
Saudi Arabia also wanted to demonstrate that it would not accept the consolidation of a hostile armed movement on its border.
Allowing the Houthis to control Sana’a and expand southwards could have been interpreted by regional rivals as a sign that Saudi Arabia was unwilling or unable to defend its strategic interests.
The intervention therefore served several purposes simultaneously: supporting Hadi, countering Iranian influence, defending Saudi territory and demonstrating regional resolve.
The strategic gamble was that military pressure would quickly reverse Houthi gains and restore the government.
That expectation proved unrealistic. The Houthis were deeply embedded in northern Yemen, the anti Houthi camp was fragmented, and air power could not create a stable political order.
5. Operation Decisive Storm: From intervention to prolonged war
On 26 March 2015, Saudi Arabia led a coalition that launched air operations against the Houthis and their allies. The campaign was named Operation Decisive Storm.
Its initial objectives included targeting air defences, missile capabilities, military camps, troop concentrations and weapons depots. The coalition sought to prevent further Houthi advances and weaken the movement’s ability to threaten the recognised government.
On 22 April 2015, the coalition announced the beginning of Operation Restore Hope. The change was presented as a shift towards political efforts and humanitarian relief, although military operations continued.
The coalition included several regional partners, with participation and commitments changing over time. The United Arab Emirates became a particularly important military actor, especially in southern Yemen and along the coast.
Why the air campaign did not win the war
Air power can destroy weapons, damage infrastructure and impose costs on an opponent. It cannot automatically produce political legitimacy, reliable local governance or national reconciliation.
The Houthis adapted by dispersing military assets, maintaining local networks and exploiting divisions among their opponents. The coalition faced difficult choices about ground operations and relied on Yemeni partners whose objectives did not always align.
The anti Houthi camp was never a single political force. Some factions prioritised restoring the recognised government; others sought southern independence or local autonomy. Those differences weakened the possibility of building a unified alternative.
The result was a prolonged conflict in which Saudi Arabia retained substantial military superiority but failed to eliminate the Houthis or restore stable national governance.
The civilian consequences
The air campaign produced serious concerns about civilian casualties and damage to infrastructure.
A UN Human Rights Council investigation reported that approximately 18,000 coalition air raids took place between March 2015 and June 2018, citing Yemen Data Project figures. It also discussed the intensity of the early campaign and serious concerns about attacks affecting civilians and civilian infrastructure.
These figures refer to a defined period and should not be confused with the total number of civilian deaths in the war.
The broader conflict has caused harm through airstrikes, shelling, landmines, missile attacks, detention abuses, restrictions on movement and the collapse of public services. Different actors have been responsible for different forms of harm, and specific incidents require careful investigation.
The coalition’s air campaign must be scrutinised, particularly where attacks affected homes, markets, ports or other civilian infrastructure. Houthi attacks and abuses must be scrutinised as well.
The destruction of port infrastructure illustrates the wider problem. Hudaydah is a critical entry point for food, fuel and humanitarian supplies. Damage to its facilities can affect civilians far beyond the immediate area of an attack by disrupting imports and increasing transport costs.
The transition from Decisive Storm to Restore Hope did not end the war. It marked a change in the campaign’s public framing while the military and political conflict continued.
6. Religion and identity: Is this a Sunni–Shia war?
Religion influences the conflict, but it cannot adequately explain it.
The Houthis emerged from Yemen’s Zaydi Shia tradition. Iran’s governing religious system follows Twelver Shia Islam, while Saudi Arabia has a Sunni majority and a state religious tradition historically shaped by Sunni interpretations.
These differences have influenced political rhetoric and perceptions of regional alliances. Yet the conflict is not simply a religious war.
Yemen’s history includes political alliances across sectarian lines and disputes driven by land, resources, patronage, regional autonomy and the distribution of power.
The Houthi alliance with former president Saleh is a clear example. Saleh’s government had fought the Houthis for years, yet the two sides cooperated when their immediate interests aligned. Their partnership later collapsed, and Saleh was killed by Houthi forces in December 2017.
This demonstrates that political calculations can outweigh religious or historical divisions.
Religious language can also intensify conflict by portraying opponents as existential enemies. When political rivals are framed as threats to an entire religious community, compromise becomes more difficult.
However, reducing the war to sectarian hostility obscures practical questions that any settlement must answer: Who controls public revenue? How will salaries be paid? What authority will local governments exercise? How will roads and ports reopen? What protections will exist for communities outside Houthi control?
These are central political and economic questions, not merely theological disputes.
7. Cross border attacks and the Saudi security dilemma
The Houthis’ missile and drone attacks on Saudi territory transformed the conflict into a direct security problem for the kingdom.
Attacks and claimed attacks against airports, military installations and energy infrastructure demonstrated that Yemen’s war could impose costs well beyond the battlefield.
Modern drones and missiles create a difficult defence problem. An attacker may use relatively inexpensive systems to force a defender to deploy costly interceptors, maintain continuous surveillance and protect critical infrastructure across a large area.
Even when most incoming weapons are intercepted, repeated attacks can create uncertainty and economic disruption.
The September 2019 attacks on Saudi oil facilities at Abqaiq and Khurais were a major turning point in regional perceptions of vulnerability. The Houthis claimed responsibility, while Saudi Arabia and the United States attributed the attack to Iran. Attribution of an individual attack requires evidence about weapons, launch locations, command and operational planning; public statements by the parties are not sufficient on their own to settle every question.
The episode nevertheless demonstrated how vulnerable critical infrastructure can be to drones and cruise missiles.
Saudi Arabia faced a strategic dilemma. Continuing military operations could impose costs on the Houthis, but the movement could retaliate against Saudi infrastructure. A reduction in hostilities could lower the immediate threat, but it would require credible arrangements to prevent future attacks.
The 2022 UN brokered truce substantially reduced major fighting and cross border attacks. It did not become a comprehensive peace agreement. Front lines remained largely frozen for a period, while political disputes, economic fragmentation and the division of public institutions continued.
This distinction is important: a ceasefire reduces violence, but peace requires institutions and agreements capable of preventing the next round of violence.
8. The UAE, Western powers and competing interests inside Yemen
Saudi Arabia’s coalition partners did not always share a common vision for Yemen’s future.
The United Arab Emirates supported the intervention but developed strong relationships with southern separatists and other local armed forces. These groups did not always share Saudi Arabia’s preference for maintaining a unified Yemeni state under the recognised government.
The Southern Transitional Council became an influential political and military actor in the south. Its expansion created tensions within the anti Houthi camp, demonstrating that opposition to the Houthis did not automatically produce agreement over Yemen’s political future.
The United States and United Kingdom supported the Saudi led coalition in various ways at different points in the conflict. Their involvement prompted debate over arms sales, military assistance, civilian harm and the responsibilities of states that support a party to an armed conflict.
Later, the United States and United Kingdom carried out strikes against Houthi targets in response to attacks on shipping in the Red Sea. Those operations were presented as attempts to protect navigation and deter further attacks. The Houthis framed their maritime campaign as part of the confrontation surrounding Gaza and Israel.
The wider lesson is that external involvement can strengthen local military actors while complicating political settlement. Each outside power may seek a different outcome, and its local partners may have goals that diverge from those of their sponsors.
9. The Red Sea crisis and global trade
Yemen’s geography gives the Houthis strategic influence beyond the country’s borders.
The Bab al Mandab Strait connects the Gulf of Aden with the Red Sea. Through the Red Sea and Suez Canal, vessels can travel between Asia and Europe without going around the southern tip of Africa.
Disruption of this route can increase shipping times, fuel consumption, insurance costs and freight prices. When operators consider the risk of missile or drone attacks too high, vessels may divert around the Cape of Good Hope.
This is why attacks on shipping can have consequences far beyond Yemen. The impact is not limited to vessels that are struck. The threat itself can alter commercial decisions and increase costs across supply chains.
The Houthis have described their maritime attacks as pressure against Israel and its supporters in the context of the Gaza war. Yet attacks and threats affecting commercial shipping have raised serious questions about the safety of civilian crews and vessels.
International maritime law does not permit indiscriminate attacks on civilian shipping. A political cause does not remove the obligation to distinguish military targets from civilian objects.
Retaliatory strikes also carry risks. Military action can damage launch sites and weapons stocks, but it can also provoke further escalation, affect infrastructure and make a political settlement harder to achieve.
By 2026, the regional context had become even more dangerous. The Council on Foreign Relations reported in April that the Houthis had entered the US–Israeli war against Iran that began in February 2026, opening another front in the wider confrontation.
This is a warning against treating Yemen as an isolated conflict. Regional escalation can increase Houthi incentives to demonstrate military relevance, while Houthi attacks can draw further outside intervention.
10. Yemen’s humanitarian catastrophe: The statistics behind the war
The most important measure of the conflict is not how many weapons each side possesses, but what has happened to Yemen’s population.
Years of war have damaged health facilities, water systems, roads, schools, homes and livelihoods. The economy has been weakened by currency instability, disrupted public revenue, fragmented institutions, restrictions on movement and trade, and interruptions to public sector salaries.
The country also faces climate related shocks and disease risks that compound the consequences of conflict.
The UN humanitarian outlook for 2026
According to the UN Office for the Coordination of Humanitarian Affairs’ 2026 Humanitarian Needs and Response Plan:
Indicator | 2026 estimate |
|---|---|
People needing humanitarian assistance and protection | 22.3 million |
People facing acute food insecurity | 18.3 million |
Internally displaced people | 5.2 million |
Children under five with acute malnutrition | More than 2.2 million |
Children with severe acute malnutrition | More than 516,000 |
People expected to need water, sanitation and hygiene assistance | 14.4 million |
Health facilities fully functional | 59.3% |
Humanitarian response funding requested | US$2.16 billion |
Source: UN OCHA, Yemen Humanitarian Needs and Response Plan 2026. These are planning estimates and indicators, not a final count of conflict deaths.
The scale of the emergency is staggering. More than half of the population is estimated to face acute food insecurity. Millions struggle to access sufficient food, safe water, healthcare and other basic services.
Malnutrition is particularly dangerous for young children. It weakens immune systems and increases the risk that otherwise treatable illnesses become fatal. When health facilities lack medicine, electricity, staff or functioning equipment, the consequences multiply.
Displacement also has long term effects. Families lose homes, income, education and social networks. Women, children, people with disabilities and marginalised communities may face additional barriers to aid and protection.
Why humanitarian assistance cannot solve the crisis alone
The UN’s 2026 response plan aims to reach 12 million people, including 9.4 million prioritised for targeted assistance based on severity. The plan requests US$2.16 billion to deliver assistance at scale.
Humanitarian aid is essential, but it cannot by itself restore a functioning economy or resolve the political divisions that sustain the conflict.
Aid agencies need reliable access, adequate funding and protection for their personnel. Restrictions on movement, bureaucratic obstacles, security threats and detention of humanitarian workers can undermine relief efforts.
All parties should facilitate impartial humanitarian assistance and protect those delivering it. Aid must not be diverted for military or political purposes.
Responsibility for civilian suffering should also be assessed carefully. Coalition airstrikes and restrictions have caused serious harm. Houthi attacks, mines, shelling, detention practices and restrictions on humanitarian work have also harmed civilians. Other armed factions have committed abuses, while the collapse of public institutions has multiplied the effects.
Acknowledging multiple sources of harm is not an attempt to excuse any party. It is necessary for a serious assessment of the conflict and for accountability.
11. International law: The standards that apply to all parties
International humanitarian law requires parties to distinguish civilians and civilian objects from combatants and military objectives. It also prohibits attacks expected to cause excessive civilian harm in relation to the concrete and direct military advantage anticipated.
Parties must take feasible precautions to reduce civilian harm. These principles apply to airstrikes, missile attacks, drone operations and other forms of warfare.
An attack on a military objective is not automatically lawful in every circumstance. Its legality depends on factors including the target, the expected civilian consequences, the military advantage anticipated and the precautions taken.
Similarly, Houthi attacks against civilian airports, energy infrastructure or commercial vessels raise serious legal questions. The circumstances of individual attacks must be examined, rather than assuming that every claim by a party to the conflict is established fact.
The legal basis for intervening in a war and the legality of how that war is conducted are separate questions. Saudi Arabia’s stated justification rested on a request from Yemen’s internationally recognised president. But even if an intervention is argued to have a legal basis, each attack must still comply with international humanitarian law.
The Houthis’ seizure of Sana’a by force also raises questions about political legitimacy. International recognition does not eliminate the need for domestic inclusion, but territorial control does not automatically confer a democratic mandate either.
A durable political settlement must protect Yemenis who oppose the Houthis as well as those who support them. It must also address the interests of southern communities and other groups that fear domination by rival authorities.
12. Current status in October 2026: The return to large scale fighting
The situation has deteriorated significantly in 2026.
A UK House of Commons Library briefing published on 5 October reported renewed Houthi–Saudi and Yemeni government fighting after a period of largely frozen front lines following the 2022 truce. It also described a major reordering of forces in southern Yemen and new Houthi advances along the Red Sea coast.
On 9 October, UN Special Envoy Hans Grundberg warned the Security Council that Yemen had slid back into full scale war, with hostilities spreading across multiple front lines. The briefing described intensified fighting in areas including Taiz, Lahj, Marib, al Jawf and Hajjah, alongside aerial attacks and a government counter offensive around Bab al Mandab.
The UN briefing also reported Houthi attacks affecting civilian and energy infrastructure in Saudi Arabia, including Abha International Airport and King Khalid International Airport in Riyadh, with civilian deaths and injuries reported.
These are serious developments. Because the front lines are changing quickly, specific operational claims should be checked against current UN reporting and independent investigations.
The renewed fighting reveals the weakness of a truce that never became a comprehensive political settlement. The cessation of large scale hostilities after 2022 reduced immediate risks, but it did not resolve questions of governance, public revenue, salaries, security arrangements or the future of Yemen’s competing authorities.
Saudi Arabia now faces a difficult strategic choice. Greater military escalation could impose costs on the Houthis, but it could also expose Saudi infrastructure to further attacks and draw the kingdom deeper into a renewed war. Diplomacy could reduce the risk of a wider conflict, but any agreement would need credible security arrangements and meaningful participation by Yemeni actors.
The humanitarian outlook makes the stakes particularly high. Further fighting threatens food supplies, health services, aid access and the livelihoods of people already facing acute deprivation.
13. What could happen next?
Several broad scenarios are possible.
Scenario one: A prolonged and dangerous stalemate
Fighting could continue across several fronts without producing a decisive military outcome. Each side might try to improve its bargaining position through local offensives, missile and drone attacks, or pressure on strategic routes.
The danger is that an attack causing mass casualties or major damage to energy infrastructure could trigger a wider cycle of retaliation.
Even without a formal declaration of regional war, civilians would face additional displacement, higher prices and greater uncertainty.
Scenario two: Regional de escalation
Saudi Arabia and Iran could pursue arrangements intended to reduce cross border attacks, constrain weapons flows, protect maritime traffic and support UN led negotiations.
Such arrangements would need credible monitoring and mechanisms for investigating violations. A political understanding between Riyadh and Tehran could reduce the regional temperature, but it would not automatically resolve Yemen’s internal conflict.
The Houthis, the recognised government, southern actors and other Yemeni constituencies would need meaningful roles in the political process.
A deal that treats Yemenis merely as pieces on a regional chessboard would risk reproducing the conditions that led to war.
Scenario three: A negotiated Yemeni settlement
The most sustainable path would combine security arrangements with political and economic agreements.
A settlement would need to address the distribution of public revenue, payment of salaries, governance, local autonomy, roads, ports, detainees, public services and the future of armed forces. It would also need to address southern political aspirations and provide guarantees for communities that fear domination by the Houthis or rival factions.
This would be difficult. The institutions are fragmented, mistrust is deep, and the armed actors have different visions for Yemen’s future.
Nevertheless, years of conflict demonstrate the limits of relying on military force alone. Saudi Arabia failed to eliminate the Houthis, while the Houthis have not established an uncontested political order across Yemen.
A lasting settlement requires credible implementation, economic recovery and sustained international support.
What would count as genuine progress?
A sustained reduction in cross border attacks and airstrikes.
Protection of commercial shipping and civilian infrastructure.
Reliable payment of public sector salaries and agreements on revenue sharing.
Humanitarian access and the release of arbitrarily detained people.
Inclusive negotiations involving the Houthis, the recognised government, southern actors and other affected communities.
Independent investigation of serious alleged violations and measures to prevent recurrence.
These are practical tests of progress. A temporary decline in fighting is important, but it should not be mistaken for a permanent solution.
Key takeaways
1. The conflict began inside Yemen. Local grievances, state weakness and the failure of the post 2011 political transition preceded the Saudi led intervention.
2. Iranian support is real and consequential. UN reporting documents foreign assistance and advanced weapons systems linked to Iranian designs, but this does not prove Tehran controls every Houthi decision.
3. Saudi Arabia had genuine security concerns. The Houthi takeover and later missile and drone attacks threatened the kingdom’s border and strategic infrastructure.
4. Military superiority did not produce a political victory. The coalition failed to restore a stable national government, while divisions among anti Houthi factions weakened its position.
5. Civilian protection must apply to every party. Airstrikes, attacks on civilian infrastructure, landmines, detention abuses and restrictions on humanitarian access require evidence based scrutiny.
6. The 2022 truce was not comprehensive peace. Renewed fighting in 2026 shows how quickly frozen front lines can collapse when fundamental political questions remain unresolved.
7. The humanitarian crisis is immense. OCHA estimates that 22.3 million people will need assistance in 2026 and 18.3 million face acute food insecurity.
8. Yemen cannot be settled only by Riyadh and Tehran. A durable solution must give Yemenis a meaningful role in determining their political future.
Conclusion: A regional rivalry built on a Yemeni tragedy
The Houthi–Saudi conflict is both a Yemeni civil war and a regional security struggle. Neither description alone explains its full complexity.
The Houthis emerged from northern Yemen’s political and religious environment, exploited the collapse of the transition and built a powerful armed movement. Iranian assistance increased their military reach and strategic importance. Saudi Arabia, fearing an Iran aligned force on its border and seeking to restore the recognised government, launched a military intervention that became a prolonged and costly campaign.
The war challenges the assumption that military power can create political order by itself. The Saudi led coalition possessed substantial air power but failed to eliminate the Houthis or establish stable national governance. The Houthis survived, developed more sophisticated weapons and used Yemen’s geography to project influence into the Red Sea. Iran gained strategic leverage, but Yemen’s institutions and society suffered devastating consequences.
The renewed escalation in 2026 demonstrates that a lull is not peace. A ceasefire without political inclusion, functioning institutions, economic arrangements and security guarantees can freeze a conflict without resolving it.
A credible way forward requires regional de escalation, protection of civilians, secure maritime navigation, humanitarian access, economic recovery and an inclusive Yemeni political process. No side can credibly claim victory while millions face hunger and the state remains fractured.
The ultimate measure of success will not be the number of targets destroyed or the amount of territory captured. It will be whether Yemenis can live safely, earn a living and determine their future without permanent war.
Frequently asked questions
1. Who are the Houthis?
The Houthis, or Ansar Allah, are a Yemeni armed and political movement that emerged from the Zaydi Shia community in northern Yemen. They took control of Sana’a in 2014 and govern much of the country’s north.
2. Why did Saudi Arabia intervene in Yemen in 2015?
Saudi Arabia said it intervened at the request of President Hadi to reverse the Houthi advance and support Yemen’s internationally recognised government. Riyadh also feared that an Iran aligned armed movement would threaten its southern border and regional influence.
3. Does Iran control the Houthis?
Iran provides significant support, including weapons related assistance and technical expertise. However, the Houthis have their own leadership, domestic interests and decision making capacity. Complete Iranian control should not be assumed.
4. What was Operation Decisive Storm?
It was the opening phase of the Saudi led coalition’s military campaign launched on 26 March 2015. The coalition subsequently announced Operation Restore Hope, although military operations continued.
5. Is the conflict a Sunni–Shia war?
Religious identity influences political language and alliances, but the war cannot be reduced to sectarian hostility. Governance, regional marginalisation, resources, state power and regional security are central drivers.
6. How many people need humanitarian assistance in Yemen?
OCHA’s 2026 response plan estimates that 22.3 million people need humanitarian assistance and protection, while 18.3 million face acute food insecurity.
7. Did the 2022 truce end the war?
No. It reduced major fighting and cross border attacks, but it did not produce a comprehensive peace agreement. UN reporting in October 2026 described renewed full scale fighting.
8. Why does the conflict threaten global trade?
Yemen lies near the Bab al Mandab Strait, a key maritime passage linking the Gulf of Aden, Red Sea and Suez Canal. Attacks or threats against ships can raise insurance and freight costs or force vessels to take longer routes.
9. Are civilian casualties caused only by Saudi airstrikes?
No. Coalition airstrikes have caused serious civilian harm, while Houthi attacks, mines, shelling and abuses, along with actions by other armed groups and the collapse of public services, have also harmed civilians. Specific incidents should be investigated on the evidence.
10. What is the most realistic path to peace?
A durable settlement would require regional de escalation and an inclusive Yemeni process addressing security, governance, revenue, salaries, public services, humanitarian access, detainees and the concerns of southern and other local actors.
