Riyadh, September 22, 2026

Saudi Arabia is once again facing one of its most difficult strategic and security challenges in years.

Recent Houthi attacks targeting Riyadh and Saudi energy infrastructure have revived a question that many had hoped was becoming less urgent:

What would happen if Riyadh once again entered a major war against the Houthis inside Yemen?

The attacks have also raised broader questions about the resilience of Saudi Arabia’s economy, its air-defence capabilities and the vulnerability of the wider Gulf security system.

The central dilemma is becoming increasingly difficult to ignore.

Saudi Arabia has the resources to wage a war. But does it have a clear path to ending one?

The Riyadh dilemma

Saudi Arabia is not entering this crisis without military or economic power.

The kingdom possesses substantial financial resources, sophisticated weapons systems, extensive energy infrastructure and one of the region’s most heavily funded militaries.

But economic strength and military strength do not automatically translate into the ability to win a prolonged asymmetric war.

The Saudi-led intervention in Yemen began in 2015 with the stated objective of restoring Yemen’s internationally recognized government and pushing back the Houthi movement.

More than a decade later, the Houthis remain a major military and political force.

They have developed and deployed ballistic missiles and drones capable of threatening targets deep inside Saudi territory.

That creates a difficult strategic question for Riyadh:

If the previous war did not eliminate the Houthi threat, what would fundamentally change in another military campaign?

The economic vulnerability

Saudi Arabia is attempting to transform its economy through Vision 2030 and reduce its dependence on oil.

A major regional war could complicate that transformation.

Repeated attacks on energy facilities, ports, pipelines, airports or other critical infrastructure would not only create direct repair costs.

They could also affect:

• investor confidence;
• insurance costs;
• shipping;
• energy exports;
• tourism;
• foreign investment;
• and the broader implementation of Vision 2030.

The issue is therefore larger than the cost of individual missile interceptions or damaged infrastructure.

The deeper concern is whether sustained insecurity could increase the economic price of maintaining Saudi Arabia’s regional ambitions.

The changing nature of the Houthi threat

The Houthis have demonstrated that they can use relatively inexpensive drones and missiles to create pressure on a much wealthier adversary.

This creates an important asymmetry.

A sophisticated air-defence system may cost millions of dollars to operate and replenish, while an attacking force may be able to launch a considerably cheaper weapon.

That does not mean Saudi air defences are ineffective.

They can and do intercept incoming threats.

But no missile-defence system provides an absolute guarantee against every attack, particularly when an adversary can launch weapons from multiple directions and use different types of systems.

The strategic problem is therefore not simply whether Riyadh can intercept individual missiles.

It is whether it can sustain that defence indefinitely without allowing the cost of the conflict to become strategically damaging.

Yemen is no longer an isolated battlefield

Another war in Yemen would take place in a dramatically different regional environment from that of 2015.

The conflict is now closely connected to the security of the Red Sea, Bab al-Mandab and the wider confrontation involving Iran and the United States.

Bab al-Mandab is particularly important because it connects the Red Sea with the Gulf of Aden and provides a major route for international shipping.

Any sustained disruption would have consequences beyond Yemen and Saudi Arabia.

Shipping costs could rise.

Insurance premiums could increase.

Supply chains could be disrupted.

And pressure could spread to Egypt, East Africa, the Gulf states and international energy markets.

This is what makes a renewed Saudi-Houthi confrontation potentially more dangerous than a conventional bilateral conflict.

Could another Saudi-led offensive backfire?

This is one of the most important questions now being debated.

A renewed Saudi campaign could take several forms.

Riyadh could rely primarily on air strikes.

It could increase military assistance to anti-Houthi forces inside Yemen.

Or it could support a broader ground campaign involving several regional actors.

Each option carries different risks.

A limited military response might fail to change the strategic balance.

A larger campaign could produce a stronger Houthi response against Saudi territory and potentially against regional infrastructure.

A ground offensive could become particularly complicated because Yemen’s geography, fragmented political landscape and history of irregular warfare make decisive military outcomes difficult to achieve.

The central question is therefore not simply:

Can Saudi Arabia strike the Houthis?

It is:

Can Saudi Arabia control what happens after it strikes them?

The Gulf’s wider vulnerability

The wars and confrontations involving Iran, the United States and regional actors have exposed the vulnerability of Gulf infrastructure to missile and drone warfare.

This does not mean that Gulf states lack military capabilities.

Saudi Arabia, the United Arab Emirates, Qatar, Bahrain and other Gulf countries possess advanced defence systems and maintain extensive security relationships with international partners.

But recent conflicts have demonstrated that sophisticated air-defence networks can face enormous pressure when attacks are numerous, dispersed and unpredictable.

The Gulf’s economic model depends heavily on stability.

Oil and gas facilities, ports, airports, financial centres and major cities all require a high degree of security.

A prolonged regional conflict could therefore create a contradiction at the heart of Gulf strategy:

The states have enormous resources to defend themselves, but their economic prosperity depends on avoiding the kind of prolonged instability that makes those resources necessary.

Iran and the wider regional equation

Any renewed Saudi-Houthi war would also have to be considered within the broader Saudi-Iranian relationship.

The Houthis are closely associated with Iran, although the movement has its own Yemeni political and military interests.

A major Saudi offensive could therefore become part of a wider regional confrontation rather than remaining confined to Yemen.

That could increase the possibility of pressure on Saudi energy infrastructure, shipping routes and other strategic assets.

It could also place greater demands on the United States and other Saudi security partners.

The danger is escalation.

One military action could produce another.

One missile launch could produce an air strike.

One attack on shipping could trigger a wider naval operation.

And a conflict that begins in Yemen could eventually involve several theatres.

Saudi Arabia’s difficult choice

Riyadh now faces two broad strategic approaches.

The first is to respond militarily and attempt to restore deterrence by demonstrating that attacks against Saudi territory will carry a significant price.

The second is to seek diplomatic mechanisms aimed at reducing the conflict while maintaining border security and preventing the Houthis from interpreting restraint as weakness.

Neither approach is without risk.

A major military response could create a prolonged conflict.

Diplomatic restraint could raise questions about deterrence and encourage further pressure if the Houthis interpret it as an opportunity.

This is the strategic dilemma facing Riyadh.

Could the Gulf become the battlefield?

The greatest danger is that Yemen could become only one part of a much wider regional confrontation.

If the Red Sea, Bab al-Mandab, the Gulf of Aden and the Gulf itself become interconnected theatres of conflict, the economic consequences could extend far beyond the immediate combatants.

The potential effects include:

Energy: disruption to oil and gas production or transportation.

Shipping: higher insurance and freight costs.

Investment: increased risk perceptions among international investors.

Infrastructure: repeated attacks on ports, energy facilities and transportation networks.

Regional security: greater dependence on foreign military protection.

Humanitarian consequences: further deterioration of Yemen’s already fragile situation.

The question would then become whether the Gulf states can absorb the economic and security costs of a prolonged confrontation.

The real test for Riyadh

Saudi Arabia today is not the same country it was in 2015.

Its economy is larger and more diversified in several areas. Its international partnerships are broader, and its ambitions under Vision 2030 are considerably greater.

But the Houthis are not the same force they were in 2015 either.

They have gained battlefield experience, developed longer-range capabilities and demonstrated their ability to connect Yemen’s conflict with the security of the Red Sea.

That creates a new strategic equation.

A renewed Saudi-led war would therefore not simply be another chapter in the Yemen conflict.

It could become a test of:

• Saudi Arabia’s military strategy;
• the resilience of its economy;
• the credibility of Gulf air defence;
• the future of Red Sea security;
• the stability of international shipping;
• and the ability of regional powers to prevent escalation.

Conclusion

Saudi Arabia may have the financial and military resources to launch another campaign against the Houthis.

The more difficult question is whether such a campaign could achieve its political objectives without producing a wider and more expensive conflict.

The experience of the previous Yemen war demonstrates the difficulty of converting overwhelming conventional resources into a decisive result against a resilient non-state actor operating from difficult terrain.

Today, the stakes are even broader.

Yemen is connected to the Red Sea.

The Red Sea is connected to Bab al-Mandab.

Bab al-Mandab is connected to global shipping.

And the security of the Gulf is increasingly connected to the wider confrontation involving Iran, the United States and other regional powers.

For Riyadh, therefore, the fundamental question may not be who possesses greater military power.

It may be something more difficult:

Who can control the escalation once the war begins?
