A renewed wave of Houthi attacks against Saudi Arabia’s critical infrastructure is exposing persistent gaps in the Kingdom’s air‑defense network, raising urgent questions about how a future Trump administration would manage the U.S.‑Saudi security partnership. Over the past weeks, Yemen’s Iran‑backed Houthi movement has launched salvos of drones and ballistic missiles at Saudi oil facilities, military bases, and civilian airports — strikes that have repeatedly bypassed or overwhelmed Saudi Patriot and THAAD batteries. For Washington, the timing is fraught: former President Donald Trump, who has signaled a return to the White House in 2026, built his Middle East policy around a transactional alliance with Riyadh, but the Houthi onslaught threatens to turn that relationship into a costly liability.
**Contexto**
The Houthi campaign against Saudi Arabia is not new. Since 2015, the group has fired thousands of projectiles into the Kingdom, but the scale and precision of recent attacks have escalated sharply. In early October 2026, Houthi forces claimed responsibility for a drone strike that ignited a fire at a major Aramco facility in the Eastern Province — the same region hit in the devastating 2019 Abqaiq‑Khurais attack that temporarily halved Saudi oil output. U.S. and Saudi officials have acknowledged that the Kingdom’s layered air‑defense system, built around American‑made Patriot PAC‑3 and THAAD batteries, has struggled to intercept low‑flying drones and hypersonic‑like ballistic missiles supplied by Iran.
Saudi Arabia has invested tens of billions of dollars in defense over the past decade, including the purchase of advanced radars and interceptors. Yet independent analysts and leaked Pentagon assessments have long noted that the Kingdom’s air‑defense network suffers from critical gaps: insufficient coverage over the vast southern border with Yemen, a shortage of high‑altitude interceptors to counter ballistic missiles, and a reliance on manual rather than automated threat‑detection systems. The Houthis have exploited these weaknesses by launching saturation attacks — volleys of cheap drones that overwhelm expensive Patriot batteries, followed by precision missiles aimed at high‑value targets.
The current onslaught comes amid a fragile ceasefire in Yemen that has repeatedly collapsed. The Houthis, emboldened by Iranian support and their own battlefield successes, have made clear they will continue targeting Saudi infrastructure as leverage in any future negotiations. For Riyadh, the immediate concern is economic: a sustained disruption to oil exports could destabilize global markets and undermine the Vision 2030 diversification plan championed by Crown Prince Mohammed bin Salman.
**Analise**
For Donald Trump, the Houthi challenge represents a test of his “America First” doctrine. During his first term, Trump took a hard line against Iran, withdrawing from the nuclear deal and ordering the killing of Qasem Soleimani. He also approved the sale of advanced weapons to Saudi Arabia, including THAAD systems, and maintained a robust U.S. military presence in the Gulf. However, Trump was also deeply skeptical of open‑ended foreign entanglements. In 2019, after the Abqaiq‑Khurais attack, he chose not to retaliate militarily against Iran, instead tightening sanctions — a decision that critics said emboldened Tehran and its proxies.
If Trump returns to office in January 2027, he will face a more dangerous Houthi threat. The group now possesses drones with ranges exceeding 1,500 kilometers and ballistic missiles that can reach deep into Saudi territory. U.S. intelligence assessments indicate that Iran has provided the Houthis with advanced guidance systems and solid‑fuel rocket motors, making their missiles harder to intercept. Meanwhile, the U.S. military’s own air‑defense resources are stretched thin by commitments in Europe and the Indo‑Pacific. A major Houthi strike that causes significant casualties or a prolonged oil disruption would force Trump to decide whether to escalate U.S. involvement — potentially deploying additional Patriot battalions or launching direct strikes on Houthi launch sites — or to pressure Riyadh to negotiate a settlement that could legitimize the Houthis as a political force.
Either option carries risks. A deeper U.S. military commitment would contradict Trump’s promise to end “forever wars” and could draw American forces into a protracted conflict with Iranian‑backed proxies. Pressuring Saudi Arabia to negotiate, on the other hand, would anger the Gulf allies who have long relied on Washington’s security umbrella and could embolden Iran across the region. Trump’s own transactional approach — demanding that Riyadh pay more for its defense — may also backfire if the Kingdom’s vulnerabilities are seen as a weakness that can be exploited by adversaries.
The Houthi onslaught also has implications for the broader U.S.‑Saudi relationship. The Biden administration, despite its early criticism of the Kingdom, ultimately deepened security cooperation, including intelligence sharing and joint air‑defense exercises. A Trump administration might reverse that trend, but it cannot afford to ignore the strategic importance of Saudi oil and the Red Sea shipping lanes. The Houthis have already demonstrated they can threaten global energy supplies and disrupt maritime traffic through the Bab el‑Mandeb strait. For Trump, the problem is not just Saudi Arabia’s defense vulnerabilities — it is that those vulnerabilities now directly affect U.S. economic and strategic interests.
