The Strategic Posture of Yemen's Houthis Amidst Regional Escalation
Iranian Appraisals and Regional Alliances
In his inaugural statement following his succession, Iran's new Supreme Leader, Mojtaba Khamenei, lauded Yemen's Houthi movement, characterizing them as "brave and loyal." The Houthis represent one of the two militia factions within Iran's "Axis of Resistance" that have not yet been directly embroiled in the ongoing Middle Eastern conflict. In contrast to Hamas in Gaza, whose offensive capabilities have been significantly degraded after three years of war with Israel, the Houthis have emerged as Tehran's most potent regional ally. Given Iran's current existential struggle, it is improbable that the Houthis will remain passive observers for an extended period.
Control Over Vital Maritime Chokepoints
Iran has already imposed restrictions on shipping through the Strait of Hormuz, one of the world's most critical maritime passages, through which one-third of global oil sea trade transits. The other crucial maritime artery is the Bab al-Mandeb Strait in the Red Sea, which remains open for now, with dozens of oil tankers gathered off the Saudi coast, being loaded with oil rerouted from the east.
While Iran possesses limited direct influence in the Red Sea, approximately a thousand kilometers distant from the Persian Gulf and Saudi Arabia, recent data reveals that nearly thirty oil tankers assembled near the Saudi port of Yanbu have become potential targets for the Houthis. With just a few missile and drone strikes, the Houthis could assist Tehran in achieving comprehensive control over regional oil transit.
A History of Disrupting Shipping and Motivations for Engagement
During the Gaza war, this militia group succeeded in paralyzing Red Sea shipping. Currently, the Houthis have limited their actions to issuing solidarity statements and releasing a propaganda music video. This video hints at potential military intervention in support of Iran, featuring AI-generated imagery of missiles and drones, and vowing to "attack, burn, and sink the faltering American Pharaohs."
According to Ahmed Nagi, a senior Yemen analyst at the International Crisis Group, "They are awaiting a signal from Iran. I believe this is a calculated choice. Ultimately, the Houthis perceive this escalation as targeting not just Iran, but the entire 'Axis of Resistance.' If Iran is weakened, they will be the next target."
Independent Strategic Decision and Domestic Challenges
From the outbreak of the Gaza war in 2023 until the ceasefire agreement between Hamas and Israel last year, the Houthis launched missile and drone attacks against vessels in the Red Sea. Hundreds of airstrikes by the United States, the United Kingdom, and Israel failed to deter this radical militia. The group's slogan famously declares: "God is greatest. Death to America. Death to Israel. A curse upon the Jews. Victory to Islam."
The group controls most of northern Yemen, including the capital, Sana'a, and receives weaponry and training from Iran. However, unlike the Iraqi Shia militias that have attacked U.S. bases, the Houthis appear to function more as allies than outright proxies. The group seems to have independently decided to participate in attacks, a decision likely made after carefully weighing their precarious domestic situation. Four years ago, the group signed a ceasefire agreement with the Saudi-led coalition.
April Longley Alley, a senior fellow at the Washington Institute for Near East Policy and a former advisor to the UN Special Envoy for Yemen, states, "The Houthis are partners, not proxies; it is their own decision. They have suffered significant losses. They need to weigh this carefully, and there will be a considerable domestic cost."
In the south, Saudi-backed militias and the nominal, albeit powerless, Yemeni official government have been poised to attack Houthi positions and push them back into their northern mountain strongholds.
The Houthi sect of Shia Islam differs from those in Iran and Lebanon; they regard their leader, Abdelmalik al-Houthi, as their most significant religious figure, holding a status above the late Ayatollah Ali Khamenei and other clerics. Alley elaborates, "They are acutely aware of the consequences of engaging in this conflict. They have only just recovered from strikes by the U.S. and Israel. Those attacks were devastating, and they are still in the process of recovery."
Alley notes that since the war began, the Houthis have been reinforcing frontline positions and deploying forces along the Red Sea coast, but it remains unclear whether these troop movements are defensive or preparation for a new wave of operations targeting vessels.
She adds, "If they have made their decision, it may simply be a matter of timing, combined with better concealment of leadership and deployment of weaponry."
The choice of timing could hinge on the duration of the war. Even if oil tankers in the Red Sea are currently loaded and depart safely, the crude oil they carry will struggle to significantly depress oil prices, a leverage Iran likely wishes to preserve for a protracted conflict.
Alley suggests, "For now, Iran creating a crisis in the Strait of Hormuz to pressure global shipping is sufficient. However, if the United States takes any action against Iran in the Strait of Hormuz, and Iran believes the Houthis need to close the Bab al-Mandeb Strait, that is when we will see Houthi intervention."
