As Houthi rebels tighten a blockade on the Red Sea, Saudi Arabia is racing to build an international coalition to protect shipping before the conflict spreads further. The blockade, imposed on July 20th, disrupted oil shipments that were already diverted to the Red Sea following the closure of the Strait of Hormuz. The Houthis accused Riyadh of “an unjust and oppressive siege” on Yemen, an allegation Saudi Arabia denies. Since the blockade, the Houthis have launched attacks on Saudi ships in the Red Sea, with Saudi Arabia responding with strikes on what it claims is a Houthi military facility at Yemen’s Hodeidah port. The Saudi Ministry of Defense has since met with nearly fifty countries in Riyadh to establish the coalition, and at least thirteen countries, including Turkey, Egypt, Pakistan, and Nigeria, have affirmed their support. This blockade has opened a new front in the wider Iran conflict, expanding attacks on tankers into waters beyond the Strait of Hormuz and pushing oil prices higher.

In a lengthy televised address before the meeting of the proposed Saudi-led coalition, Houthi leader Abdul-Malik al-Houthi proclaimed, “The indicators show that the Saudi side is heading towards full escalation, and we will respond to its full escalation with full escalation.” A minister of Yemen’s internationally recognized government accused the Houthi rebels of acting under Iranian guidance to establish a system of tolls for ships passing through the Red Sea and the Bab al-Mandeb Strait. In a Truth Social post, President Donald Trump stated that Iran will be held responsible for future Houthi attacks and the Houthis themselves. Shipping data from the analytics platform Kpler shows the effect already taking hold; Red Sea shipping has slowed considerably, with only eleven cargo vessels passing through the strait in a recent stretch, the lowest number in months.

This potential new front in the Iran, U.S., and Israel war is alarming, as it would make the path to peace negotiations much more difficult. The proposed coalition by Saudi Arabia, centered around military deterrence, risks further escalation, especially if other gulf states are included in the military defense for ships. Direct gulf state involvement could be read by Iran not as a defensive measure against the Houthis, but as a wider anti-Iran alignment, drawing more countries directly into the broader conflict and adding another front to the war in the region. Deterrence is not a permanent solution, and one must be sought between Saudi Arabia and Iran, as Iran continues to fuel the Houthis’ actions. A similar coalition led by the U.S. was formed in 2023 and 2024 to protect shipping from Houthi attacks tied to the war in Gaza, but the attacks continued regardless. Security coalitions can manage outright violence in the short term, but escalation risk grows the longer a real resolution is delayed.

The history of this conflict is directly tied to the Yemen civil war, which began in 2014, when the Houthi rebels, backed by Iran, seized the capital of Sanaa and much of northern Yemen from the recognized government, sending it into exile. Saudi Arabia intervened militarily in 2015, aiming to restore the government, beginning a war that has continued in various forms and clashes for over a decade. The Houthis have used Yemen’s access to the Red Sea and crucial global shipping lanes as leverage, especially in 2023 and 2024, when they targeted Israeli vessels in response to Israel’s war in Gaza. This new blockade, however, adds a new front to the broader Iran conflict that began in February 2026, connecting Yemen’s long civil war to the wider regional confrontation between Iran, Saudi Arabia, and their allies. It’s worth noting that Saudi Arabia and Iran restored diplomatic relations in 2023 through a China-brokered deal, proof that de-escalation between these two rivals is possible when both sides have an incentive to pursue it.

The coalition, if used solely for military deterrence, has a high chance of failure if not followed by larger conversations between Iran and Saudi Arabia. What resolution actually requires is a return to that same diplomatic table, this time addressing Yemen directly rather than treating it as a proxy battleground. Military deterrence can act as a cover for a larger military escalation in the region and can become another longstanding clash rather than a step toward peace. Resolving this conflict requires addressing the rivalry between Iran and Saudi Arabia head-on, along with a genuine resolution to Yemen’s own civil war, not another coalition managing the fallout of a fight nobody has tried to end.
