Why Saudi Arabia’s Last War in Yemen Turned Into a Quagmire

The Saudi‑led coalition’s renewed offensive against the Iran‑backed Houthi militia in Yemen has quickly become a stark illustration of how a seemingly straightforward military intervention can devolve into a protracted and costly quagmire. When the coalition announced the latest campaign, officials framed it as a necessary step to restore the internationally recognised government of President Abdrabbuh Mansur Hadi and to curb the growing influence of Tehran in the Red Sea corridor. Yet the reality on the ground, shaped by a complex tapestry of local grievances, shifting alliances and humanitarian catastrophe, has rendered the operation far more intricate than the coalition’s initial statements suggested.From the outset, the coalition’s strategy has hinged on air power, naval blockades and limited ground incursions, mirroring the approach that characterised its earlier forays into the conflict that began in 2015..

However, the Houthis have adapted, employing a mix of guerrilla tactics, mobile artillery and increasingly sophisticated missile systems that have reached as far as Saudi oil facilities and even the United Arab Emirates. Their capacity to launch drones and ballistic missiles from within Yemen’s rugged interior has forced the coalition to divert resources to homeland defence, stretching its operational bandwidth and prompting criticism that the campaign is eroding the very security it set out to protect.Compounding the military challenges are the deep‑seated political fault lines that have long divided Yemeni society. The Houthi movement, rooted in the Zaidi Shia community of the north, enjoys significant popular support in regions where the central government’s presence has historically been weak..

Conversely, many southern factions, including the Southern Transitional Council, harbour resentment toward both the Hadi administration and Saudi involvement, fearing that a restored central authority could undermine their aspirations for autonomy. This fragmented landscape has made it difficult for the coalition to secure reliable local partners, resulting in a reliance on fragmented militias whose loyalties can shift with the promise of pay or political concessions.The humanitarian dimension has further complicated the coalition’s calculus. United Nations agencies estimate that more than 24 million people—roughly three‑quarters of Yemen’s population—now require assistance, with food insecurity, disease outbreaks and displacement reaching unprecedented levels..

The coalition’s naval blockade, intended to choke off supplies to the Houthis, has been widely criticised for exacerbating civilian suffering by restricting the flow of essential goods, including fuel and medical supplies. International pressure to ease restrictions has led to periodic adjustments, but each concession is swiftly followed by accusations from Riyadh that it undermines the campaign’s objectives, creating a cycle of tension between humanitarian imperatives and military goals.Economic considerations are equally salient. Saudi Arabia has poured billions of dollars into the Yemeni theatre over the past decade, funding not only combat operations but also reconstruction projects aimed at bolstering the Hadi government’s legitimacy..

Yet the prolonged stalemate has strained Riyadh’s treasury at a time when domestic diversification efforts under Vision 2030 demand substantial investment. Moreover, the war’s impact on regional trade routes—particularly the Bab al‑Mandeb strait, a vital conduit for global oil shipments—has heightened concerns among international investors, prompting calls for a diplomatic resolution that could restore stability and safeguard economic interests.Diplomatically, the conflict sits at the intersection of several competing agendas. Iran’s support for the Houthis, though denied by Tehran, remains a persistent point of contention, fueling broader Saudi‑Iranian rivalry that extends beyond Yemen’s borders..

At the same time, the United States and European Union have oscillated between backing the coalition’s security objectives and urging a negotiated settlement, reflecting a delicate balance between counter‑terrorism priorities and the desire to avoid entanglement in an intractable civil war. Recent back‑channel talks, facilitated by the United Nations, have produced modest confidence‑building measures, such as limited ceasefires for humanitarian aid, but a comprehensive political framework remains elusive.Within the coalition, internal dynamics have also shifted. While Saudi Arabia continues to dominate decision‑making, the United Arab Emirates has increasingly focused on supporting its own network of proxy forces, particularly in the south, often operating with a degree of autonomy from Riyadh’s central command..

This divergence has occasionally led to operational friction, as differing priorities surface on the battlefield. The coalition’s reliance on private military contractors and foreign mercenaries further blurs lines of accountability, raising concerns about compliance with international law and complicating efforts to assess the true cost of the campaign in both human and financial terms.The media narrative surrounding the campaign reflects this complexity. Early reports lauded the coalition’s swift strikes against Houthi command centres, portraying them as decisive blows that would pave the way for a quick resolution..

As the conflict has dragged on, however, coverage has shifted toward the mounting civilian toll, the proliferation of missile attacks on civilian infrastructure, and the growing sense that the coalition is fighting a war it cannot win militarily. Analyses from think‑tanks and academic institutions now stress that a purely kinetic approach is insufficient to address the underlying political grievances that sustain the insurgency.Looking ahead, experts caution that without a robust diplomatic push, the war risks becoming a self‑reinforcing vortex. Each escalation in hostilities invites reciprocal retaliation, which in turn fuels further militarisation and deepens humanitarian distress..

A potential pathway out of the quagmire would require a multilateral framework that simultaneously addresses security guarantees for Saudi Arabia, a political settlement that accommodates the diverse aspirations of Yemeni factions, and a credible mechanism to lift the blockade while ensuring that aid does not fall into the hands of combatants. Such a comprehensive approach, however, would demand concessions from all parties—a prospect that remains politically fraught.In the final analysis, the latest Saudi‑led campaign in Yemen underscores how modern conflicts often transcend the traditional calculus of battlefield victories. The interplay of regional power politics, internal fragmentation, humanitarian imperatives and economic constraints has transformed what was initially presented as a limited operation into a protracted entanglement with far‑reaching consequences..

As the coalition grapples with mounting costs and diminishing returns, the prospect of a negotiated settlement appears increasingly urgent, not only to halt the bloodshed but also to prevent the conflict from further destabilising an already volatile region..
