The Houthis, Iran’s War and Yemen’s Test of Deterrence
The bottom line for decision-makers is clear:
If the Yemeni state does not build deterrence capacity, maritime sovereignty and a unified diplomatic position, the Houthis and Iran will try to turn Yemen’s geography into a tool of threat. If the government uses this moment effectively, the danger may become an opportunity to re-anchor the state within the regional and international security equation.
Methodology and Analytical Approach
Abaad Observatory for Early Warning and Strategic Indicators adopts a multi-stage monitoring and analysis methodology designed to transform raw materials, news items, reports, and dispersed data into indicators that can be understood, measured, and assessed. The aim is to help decision-makers, researchers, and relevant stakeholders read ongoing developments in Yemen and anticipate their possible trajectories.
The methodology begins with collecting monitored materials from media sources, official statements, local and international reports, organizational outputs, and available field indicators. These materials are then classified into key tracks: political, economic, social, military, security, rights, and humanitarian indicators.
After classification, the materials are analyzed across four main levels: event intensity, indicator direction, level of impact, and early-warning significance. The Observatory does not treat news items as isolated incidents, but rather as signals that may reveal broader trends, rising risks, or exploitable opportunities.
Abaad Observatory for Early Warning and Strategic Indicators also uses artificial intelligence tools to support the processing of raw information, sorting of materials, detection of recurring patterns, classification of indicators, and generation of initial readings that help the analytical team produce faster and more structured situation assessments.
Artificial intelligence is not used as a substitute for human judgment or editorial responsibility. It is used as an assisting tool within a research and analytical process supervised by the Observatory’s team. All outputs are subject to human review, consistency checks, editorial refinement, and political and strategic interpretation before being approved in the final version.
Fixed Editorial Note
This report is not intended to provide a monthly news archive or to simply restate all developments in chronological order. Rather, it seeks to produce an analytical reading directed at decision-makers. Accordingly, the issues addressed in this report are arranged according to their level of impact and strategic significance, not merely according to the date on which they occurred.
Therefore, some events that may appear limited in media volume may receive greater analytical weight if they are connected to the future of the state, the monopoly of force, unified security command, the settlement track, or the rights and humanitarian situation.
First: Executive Summary
March 2026 revealed a clear shift in the level of threat associated with the Houthis: from warning about the possibility of their involvement in Iran’s war to a phase of open declaration and operational alignment. The Houthi group announced the start of its military participation alongside Iran. This coincided with Iranian threats to close Bab al-Mandab through the Houthis, the interception of a ballistic missile launched from Yemen toward Israel, and UN warnings about the danger of dragging Yemen into the regional war.
The main headline of March was the Yemeni government’s assertion that it will not allow Yemen to be turned into a platform for threatening regional and international security. This position reflects a shift in government discourse from political warning to a deterrence equation that connects Yemeni sovereignty, Red Sea and Bab al-Mandab security, and the protection of the region from the use of Yemeni territory as a proxy platform for Iran.
At the same time, the monitoring showed that the Houthis no longer hide their connection to Iran’s regional calculations. They moved from the language of “support” to the declaration of participation, exposing Yemen to greater military, economic, and humanitarian consequences and placing the government before the test of preventing the country from becoming an arena of open regional escalation.
March also revealed that the process of internal state reorganization is continuing. The government spoke of rebuilding institutions and increasing public revenues, while military readiness was raised and new appointments were made in the Nation Shield Forces and the General Staff. However, these steps coincided with indicators of domestic fragility, including assassination attempts in Marib and Shabwa, the continued absence of part of the state leadership from inside Yemen, and the persistence of urgent rights and humanitarian files.
Economically, the Red Sea and Bab al-Mandab emerged as both economic and security indicators. Egyptian warnings highlighted the danger of threats to Bab al-Mandab for Egypt’s national security and economy, while the European Operation Aspides reported securing the passage of more than 1,660 commercial vessels in the Red Sea.
On the humanitarian and rights tracks, detainees, abductees, press freedom, irregular migration, famine risk, and the impact of regional escalation on humanitarian conditions remained highly sensitive indicators. They show that regional war threatens not only security, but also civilian life and the humanitarian operating environment.
Second: General Risk Indicator
Overall risk level: Red / Very High
The risk indicator in March rises to an advanced red level because five major factors converged.
First, the Houthis announced the start of military participation alongside Iran, moving the group from a potential threat to a direct actor in the regional conflict.
Second, Iran threatened to close Bab al-Mandab through the Houthis, meaning that Yemen is being used in Iranian discourse as a maritime pressure card affecting trade, energy, and global supply chains.
Third, government and UN warnings increased over the risk of dragging Yemen into the regional war, reflecting an understanding that any Houthi escalation could open the door to strikes, reactions, and interventions that go beyond Yemen’s internal conflict.
Fourth, security fragility persisted inside liberated areas, especially through assassination attempts, the need to raise military readiness, and the strengthening of military and security leadership at a moment of severe regional turbulence.
Fifth, humanitarian and rights pressures intensified, with the continued detainee file, growing famine risks, migrant deaths and disappearances on the Red Sea route, and ongoing targeting of journalists.
The risk in March does not lie only in Houthi military escalation. It lies in the possibility that Yemen may become a regional confrontation platform, where Yemeni geography, islands, coasts, ports, borders, missiles, and drones are used as pressure tools in a war whose decision Yemen does not own.
Third: Key Transformations in March
1. Political Transformation: From Warning to a Deterrence Equation
March saw a shift in government discourse from general warnings about Houthi involvement in Iran’s war to a firmer political position: Yemen will not be allowed to become a platform for threatening regional and international security.
This shift is important because it links Yemeni sovereignty with regional and international security. The government is no longer presenting the issue merely as an internal dispute with the Houthis, but as a threat extending beyond Yemen to the Red Sea, Bab al-Mandab, Saudi Arabia, the Gulf, and international trade.
The repeated Yemeni condemnations of Iranian attacks on Arab and Islamic states, and Yemen’s welcome of international resolutions condemning Iranian attacks, reflect an attempt to build a diplomatic alignment against the use of the Houthis as an Iranian instrument.
The strategic implication is that the government is trying to move the Houthi file from a purely domestic issue into a regional and international security file. This may open opportunities for political and security support, but it also places greater responsibility on the government to present a clear vision on deterrence, de-escalation, and protecting Yemeni territory from proxy use.
2. Regional Transformation: Yemen at the Center of Iran’s War and Red Sea Risks
March was decisive in linking Yemen to the regional war. The Houthis announced military participation alongside Iran, Iran threatened to close Bab al-Mandab through the Houthis, and reports referred to the interception of a missile launched from Yemen toward Israel.
This means Yemen is no longer merely affected by regional tensions. It is now at risk of becoming one of Iran’s pressure tools against the United States, Israel, and regional states.
In this context, Bab al-Mandab and the Red Sea gain multiplied importance. Threats to navigation do not harm Yemen alone; they affect Egypt, Saudi Arabia, the Horn of Africa, Europe, and global supply chains. Therefore, the role of the European Operation Aspides and its report of securing the passage of more than 1,660 vessels is not a minor security detail, but an indicator of the growing internationalization of the Red Sea file.
The implication is that Yemen faces a delicate equation: the more the Red Sea gains international importance, the greater the opportunity to support the Yemeni state; yet the greater the risk that Yemen may be bypassed if it fails to present itself as a capable partner in securing maritime routes.
3. Military and Security Transformation: Raising Readiness in the Face of a Dual Threat
In March, the military and security indicator rose through heightened readiness, warnings by the Chief of Staff about the implications of regional developments, new appointments in the Nation Shield Forces and the General Staff, the seizure of an Iranian smuggling vessel heading to the Houthis, and assassination attempts in Marib and Shabwa.
This indicates that the state faces a dual threat: an external/regional threat represented by the Houthis as an instrument in Iran’s war, and an internal threat represented by security fragility, assassination attempts, and the targeting of political and military figures.
The seizure of an Iranian smuggling vessel heading to the Houthis strengthens the conclusion that the Houthi threat does not rely only on political decisions or ideological rhetoric. It is also sustained by supply, smuggling, and weapons networks that must be dismantled through sustained security, maritime, and intelligence efforts.
The strategic implication is that deterrence cannot be achieved through statements alone. It requires a readiness system covering frontlines, coasts, entry points, intelligence, the Coast Guard, and political communication with regional and international partners.
4. Economic Transformation: Bab al-Mandab as an Economic Stability Indicator
Although direct economic materials were limited, the economic dimension in March was strongly present through Bab al-Mandab and the Red Sea. An Egyptian parliamentarian warned that threats to Bab al-Mandab represent a direct danger to Egypt’s national security and economy, while Operation Aspides announced that it had secured the passage of more than 1,660 commercial vessels.
This means the maritime threat has become an economic indicator no less important than the exchange rate or salaries. Closing or threatening Bab al-Mandab increases shipping costs and affects ports, trade, insurance, energy, food, and the stability of countries connected to this corridor.
Domestically, the government continued to speak about increasing public revenues and supporting economic recovery plans. It also discussed with China the activation of cooperation under the Belt and Road Initiative and projects related to energy and infrastructure.
The implication is that Yemen has a strategic economic opportunity if it restores its role in protecting maritime corridors. However, it may also become a regional economic burden if the Red Sea remains hostage to the Houthis and Iran.
5. Rights and Humanitarian Transformation: Civilians Pay the Price of Escalation
March showed that regional escalation threatens not only frontlines and maritime corridors, but also civilians and vulnerable groups. International reports warned of an expanding famine risk in Yemen due to regional tensions, while the United Nations warned of further deterioration in the already fragile humanitarian situation as a result of military escalation.
The detainees and forcibly disappeared file also remained stalled, with disagreement over exchange lists involving thousands of detainees, and renewed calls for the release of UN staff and humanitarian workers held by the Houthis.
Press freedom concerns also remained visible, including the killing of journalist Abdul-Samad Al-Qadi and the unlawful summons of a journalist in Hadramawt. The migrant tragedy also resurfaced, with 2025 recorded as the deadliest year on the Red Sea migration route.
The implication is that rights and humanitarian issues must be read as part of early warning. Every expansion of the regional war will increase hunger, migration, violations, service collapse, and the vulnerability of Yemeni society to recruitment, smuggling, and political blackmail.
Fourth: What March’s Indicators Mean for Decision-Makers
March’s indicators show that Yemen has entered a more dangerous phase than warning alone. The Houthis declared military alignment with Iran, Iran threatened to use Bab al-Mandab through the Houthis, and the Yemeni government declared that it will not allow Yemen to become a platform for threatening regional and international security.
This means decision-makers face three interconnected tests.
The first is the test of deterrence: can the state prevent the Houthis from using Yemen as an Iranian military platform?
The second is the test of maritime sovereignty: can the government turn international interest in the Red Sea into direct support for Yemeni state capacities, rather than arrangements that bypass it?
The third is the domestic test: can the government raise readiness and stabilize institutions without being distracted by assassination attempts, internal fragility, and political differences?
The most important indicator is that Yemen has become central to a regional equation that cannot be managed through scattered reactions. What is needed is an integrated Yemeni strategy that brings together diplomacy, deterrence, maritime security, military readiness, and humanitarian protection.
Fifth: Rising Risks
1. Yemen Becoming a Proxy War Platform
The Houthi announcement of military participation alongside Iran increases the risk that Yemeni territory, coasts, missiles, and drones will be used in a conflict that does not serve Yemen’s national interest.
2. Threats to Bab al-Mandab and the Red Sea
Iran’s threat to close Bab al-Mandab through the Houthis places international navigation, trade, energy, and the national security of affected coastal and regional states at risk.
3. Declining State Role if Institutional Readiness Is Absent
If the government relies on statements without building maritime, military, and intelligence capabilities, it may shift from a needed actor to a marginal party in an international equation.
4. Assassinations and Domestic Fragility
Assassination attempts in Marib and Shabwa show that the government-controlled interior itself needs stronger security control and more effective protection and investigation mechanisms.
5. Worsening Hunger, Migration and Violations
Any regional escalation will increase food costs, disrupt supplies, weaken humanitarian work, increase irregular migration, and deepen the suffering of detainees and forcibly disappeared persons.
Sixth: Available Opportunities
1. Building International Support for the Yemeni State
Growing concern about the Houthis and the Red Sea gives the government an opportunity to present itself as an essential partner in protecting regional and international security.
2. Turning Bab al-Mandab into a Sovereignty File, Not Only a Crisis File
Rather than limiting itself to warning against threats, the government can launch a Yemeni vision for Bab al-Mandab security that includes the Coast Guard, ports, intelligence, and maritime partnerships.
3. Strengthening Cooperation With Europe, China and Regional Partners
The European Operation Aspides, cooperation with China in infrastructure and energy, and Saudi-British support for stability are all opportunities for building practical partnerships.
4. Using Smuggling Seizures Strategically
The seizure of an Iranian smuggling vessel should be transformed into a political, security, and international file proving that support for the Houthis is not merely rhetorical but part of a cross-border supply network.
5. Turning the Humanitarian File into a Pressure Track
Detainees, UN staff, famine risk, and migrants can become humanitarian and political pressure files against the Houthis if managed professionally and documented carefully.
Seventh: Possible Scenarios
Scenario One: Containment Through Coordinated Deterrence
Probability: Medium
The government, with Saudi and international support, succeeds in limiting Houthi escalation, strengthening its presence in the Red Sea file, and turning the threat into an opportunity to build a broader security partnership.
Scenario Two: Limited Maritime Escalation
Probability: Medium to High
The Houthis carry out limited operations or intermittent threats in the Red Sea and Bab al-Mandab to demonstrate involvement in Iran’s war without entering a full confrontation. This raises shipping costs and increases international military presence.
Scenario Three: Exposure of Domestic Fragility
Probability: Medium
Assassination attempts or internal disturbances increase in liberated areas, weakening the government’s ability to focus on the Houthi and regional threat.
Scenario Four: Accelerated Humanitarian Deterioration
Probability: Medium to High
Regional escalation leads to reduced funding, disrupted supplies, higher food prices, worsening famine risk and migration, and additional social and humanitarian pressure.
Eighth: Recommendations for Decision-Makers
1. Build a Clear Yemeni Deterrence Strategy
The government should define what constitutes the use of Yemen as a threat platform and what political, military, legal, and diplomatic tools it will use to prevent it.
2. Establish a National Red Sea and Bab al-Mandab Security Cell
This cell should include the government, Coast Guard, ports, intelligence, naval forces, and diplomatic bodies, and should coordinate with Saudi Arabia, Egypt, Europe, and the United States.
3. Internationalize the Smuggling File
All arms-smuggling and Iranian-support operations for the Houthis should be documented and turned into evidence before the UN Security Council, the European Union, and maritime security bodies.
4. Raise Readiness Without Militarizing Public Life
Readiness is necessary, but it must be institutional and disciplined so it does not become disorder, overlapping authority, or uncontrolled mobilization.
5. Protect Political and Military Leaders in Liberated Areas
Assassination attempts require a review of protection plans, faster investigations, and transparent publication of results to prevent recurrence.
6. Link Red Sea Security to Economic Recovery
The government should present a clear message: protecting Bab al-Mandab is not only a security matter; it is also a condition for the recovery of ports, trade, investment, energy, and food security.
7. Prioritize the Humanitarian File in Diplomatic Engagement
Famine, detainees, UN staff, and migrants should be part of every international discussion on escalation, not marginal files.
8. Develop a Unified Political Message
State institutions should speak with one message: Yemen is not Iran’s platform; the Houthis are responsible for any escalation; and the Yemeni state is the legitimate partner in protecting regional and international security.
Ninth: Concluding Situation Assessment
March 2026 marked the Houthis’ transition from threat to declaration, and from political support for Iran to military alignment with it. In response, the Yemeni government moved from warning to formulating a deterrence position centered on preventing Yemen from being used as a platform for threatening regional and international security.
The risk is high because Yemen has entered the center of a war whose decision it does not control. The opportunity also exists because this risk gives the government space to redefine the role of the Yemeni state as a partner in protecting the Red Sea and Bab al-Mandab, not as a marginal actor in an internal crisis.
