The recent Houthi attacks on Saudi Arabia, including a deadly strike on Riyadh’s King Khalid International Airport on October 10, mark a dangerous escalation. The confrontation has become more than an extension of the war in Yemen. It can no longer be understood as a limited military clash between a state and an armed group.
The region is entering a more dangerous phase. Iran’s calculations intersect with the ambitions of armed groups, while the Gulf becomes an arena for military and economic pressure. The danger lies less in the number of missiles and drones launched than in the targets chosen and the political messages behind them. These attacks could gradually erode the rules of engagement that have so far helped prevent a wider regional confrontation.
There is a fundamental difference between striking a military facility during an armed conflict and bringing war into passenger terminals and crowded public spaces. The latter goes beyond military escalation. It challenges the legal and moral limits of warfare and creates risks that the parties may struggle to contain.
The Risk of a Wider Conflict
It would be a mistake to view the Houthis as a local group operating independently of regional power dynamics. Over the past several years, they have become part of a wider military and political network linked to Iran. This network allows Tehran to exert pressure beyond its borders.
That relationship does not mean every Houthi decision follows a direct Iranian order. The group has its own calculations and interests. Still, the overlap between Iranian interests and Houthi capabilities makes Yemen a particularly sensitive front for Gulf security.
Tehran may see broader Houthi attacks as a way to raise the cost of confrontation for its adversaries. This could serve efforts to strengthen its negotiating position or ease the military and economic pressure it faces. In such calculations, the Houthis could become a means of wearing down opponents, even at the risk of severe damage to the group’s military capabilities and organizational structure. Regional powers that rely on proxies may be more willing to absorb losses among their allies than direct losses on their own territory.
Yet escalation through proxies carries an inherent contradiction. As attacks spread and impose greater costs on targeted states, political and military pressure grows to eliminate the sources of the threat rather than simply contain them. An apparent bargaining chip can become a strategic liability once red lines are crossed.
From Gulf Airports to Iraqi Armed Groups
The risks extend beyond Saudi Arabia. Networks of Iran-linked armed groups in Iraq, Yemen, and elsewhere could open several fronts if the regional confrontation widens. One scenario that deserves serious attention is the possible involvement of Iraqi armed groups in further attacks on strategic facilities or critical infrastructure across the region.
The danger would increase if those attacks reached international airports, commercial centers, and crowded civilian facilities. This does not mean such attacks are inevitable or that decisions to carry them out have already been made. It is, however, a security risk that requires preparation. Drones and long-range missiles are increasingly available to armed groups operating outside the institutional constraints of states.
This presents Gulf states with a central dilemma. They face more than a conventional military threat that can be deterred by balancing military capabilities. They also face asymmetric conflicts that can target economies, societies, and public confidence in government as much as military facilities.
Disrupting an international airport or threatening shipping does not require a military victory. A persistent threat alone can produce mounting economic and psychological costs.
The Red Sea and the Global Economic Cost
Houthi attacks on commercial vessels have shown that disrupting shipping does not require direct control of a maritime chokepoint. Threats to passing ships can be enough to force shipping companies to reassess their routes. Insurance premiums rise, and some vessels take longer, more expensive journeys.
The consequences have extended beyond the states involved in the confrontation. Egypt, countries in the Horn of Africa, and the global economy have all been affected, although to different degrees.
Egypt has been among the hardest hit. Reduced traffic through the Suez Canal has hurt an important source of foreign currency and government revenue. The decline in canal revenues during 2024 illustrates how attacks by an armed group in the southern Red Sea can damage the economy of a country that is not directly involved in military operations against it.
Countries in the Horn of Africa have also faced disruptions to maritime trade and increased security risks. The scale and nature of the damage vary across countries. Yet the broader implication is clear: the Houthi threat extends beyond Yemen and Saudi security. It raises questions about the security of international shipping routes and the international community’s ability to protect trade from military coercion.
This next phase requires the states of the Gulf Cooperation Council (GCC) to move beyond expressions of political solidarity. They need to align collectively behind Saudi Arabia, support its efforts to protect its national security, and back Yemen’s legitimate government against Houthi threats. Attacks on Saudi territory have become a test of Gulf unity and the credibility of collective security and defense.
Statements of condemnation are insufficient. Solidarity must translate into practical measures. These include activating joint Gulf defense mechanisms, strengthening military and intelligence coordination, and improving protection for critical facilities and maritime routes.
GCC states also need a unified political position that supports Yemen’s legitimate state institutions and prevents the Houthi armed group from imposing political and military realities by force. Yemen’s stability has become an integral part of Gulf security.
Perhaps the most important lesson is that Gulf security cannot remain dependent on responses to individual attacks. The challenge requires a regional strategy that addresses the sources of threats and the networks that finance and arm them. Military defense must be connected to economic security, maritime security, and infrastructure protection.
Differences among Gulf states on particular issues do not change the risks they share when airports, ports, and energy routes become potential targets. Collective security requires a shared strategic commitment: an attack on any Gulf state threatens them all. Defending Yemen’s stability and sovereignty is therefore also a defense of the Gulf’s security and future.
Who Can Start a War, and Who Can Stop It?
The most dangerous feature of the current confrontation is the growing influence of armed groups over regional decisions about war and peace. Their military strength is only part of the problem.
When an armed group can threaten an international airport or disrupt a maritime passage, it gains more than the ability to inflict violence. It seeks a role in shaping regional security without assuming the political and legal responsibilities borne by states.
Iran may calculate that opening multiple fronts and dispersing threats will make confrontation more costly for its adversaries than negotiation. But the strategy could backfire. Wider attacks may narrow the space for diplomacy and strengthen military coordination among Iran’s opponents. Armed groups that once provided leverage could instead become a drain on political and military resources.
The region does not need another conflict to understand the danger of crossing the limits of engagement. Recent years have shown that launching missiles is easier than containing their consequences. Using civilians as instruments of pressure does not produce a stable political settlement. It creates the conditions for the next crisis.
The question for Tehran and its allies is what leverage they would retain if the war expanded beyond their ability to stop it. In the Middle East, a weaker actor may be able to trigger a major confrontation. It may have far less ability to survive the consequences.
