Yemen's Trap Is Already Sprung: Why the Houthi Front Will Define How This War Ends

Yesterday, Yemen's Houthi movement fired a barrage of ballistic missiles at southern Israel, formally entering the 2026 Iran war after a month of conspicuous silence. The Israeli military said it intercepted a missile. But the real question isn't whether Houthi projectiles reach Israel. It's whether the Houthis resume attacks on Red Sea shipping. If they do—and their military spokesman Yahya Saree said Friday that "our fingers are on the trigger"—the United States will face a problem it has tried and failed to solve twice before, at the worst possible moment.

I've been tracking the Houthi maritime campaign since it began in November 2023, and I want to walk through why this particular front matters more than most commentators seem to realize. The conventional view treats Yemen as a sideshow, a secondary theater the Pentagon can manage with a few destroyers while it prosecutes the main campaign against Iran. I think the evidence says otherwise.

Let's start with what we actually know from the last two rounds. Between November 2023 and January 2025, the Houthis attacked over 190 ships, sank two, seized one, and forced 60% of commercial shipping to reroute around Africa. The Biden administration's Operation Poseidon Archer conducted strikes throughout 2024 but failed to halt the attacks. Then Trump's Operation Rough Rider, from March 15 to May 6, 2025, hit over 1,100 targets across Yemen in 52 days. CENTCOM claimed ballistic missile launches dropped by 69% and drone attacks by 55%. Those numbers sound impressive. But here's the problem: the US intelligence community's own assessment, reported by the New York Times, concluded the strikes caused only "some degradation" and that the Houthis were in a position to "easily reconstitute, regroup, and rebound." The West Point Combating Terrorism Center's detailed analysis was even more blunt, finding that "the United States failed to defeat, decisively deter, or even significantly degrade the group." The campaign ended not with Houthi capitulation but with a negotiated ceasefire in which the Houthis agreed only to stop targeting US-flagged ships. They claimed it was the US that "backed down."

This history matters because it demonstrates a core dynamic: standoff strikes can temporarily reduce Houthi attack tempo, but they cannot eliminate the group's capacity. The Houthis survived a decade-long Saudi bombing campaign (the Saudis thought it would last "six weeks," as the West Point analysis noted), and they survived two US campaigns. The mountainous terrain, underground storage facilities, and Iranian resupply pipeline all contribute to this resilience. But there's something more fundamental going on. As IISS reported in April 2025, the Houthis have developed indigenous arms production capabilities alongside their Iranian supply line. Guidance components, engines, and seekers still require Iranian inputs, but the group can assemble and produce significant quantities of simpler drones and explosive boats domestically. Cutting the supply line hurts, but it doesn't shut down operations.

Now consider the resource competition problem. The US currently has three carrier strike groups deployed or deploying to the Middle East: the USS Abraham Lincoln in the Arabian Sea, the USS Gerald R. Ford (which withdrew for repairs to Crete after a fire in mid-March and is now returning), and the USS George H.W. Bush preparing to deploy. That is the largest concentration of American naval power in the region since 2003. These assets are consumed by Operation Epic Fury—the strikes on Iran itself, which CENTCOM says have hit over 9,000 targets. Iran has responded with near-daily missile and drone attacks on Israel, US bases across six Gulf states, and commercial shipping in the Strait of Hormuz, which it has effectively closed.

Here's the bind: if the Houthis resume Red Sea attacks, the US would need to divert naval assets to conduct intercepts, escort convoys, and strike Houthi launch sites—all while those same Aegis-equipped destroyers are needed for ballistic missile defense against Iran's strikes on Gulf allies and for carrier protection. The National, a UAE-based outlet, put it directly: a renewed Houthi campaign "could force the US to divert assets from strikes on Iran to target launch sites and explosive-laden boats." There are only so many ships. The CBO's 2025 analysis found the battle force fleet at 295 ships and projected it would shrink to 283 by 2027. You cannot run a three-carrier war against Iran, defend six Gulf states from Iranian retaliation, reopen the Strait of Hormuz, AND suppress Houthi attacks in the Red Sea simultaneously. Something gives.

The allied burden-sharing picture makes this worse, not better. One of the most striking features of this conflict has been the near-total collapse of coalition support. Germany's Defense Minister Boris Pistorius declared bluntly: "It is not our war. We did not start it." British PM Keir Starmer said the UK "will not be drawn into the wider war." Spain called it illegal and refused to allow use of its bases. France, Italy, Greece, Japan, and Australia all declined to send ships. Trump called NATO allies "cowards" and threatened the alliance's future. The EU's foreign policy chief Kaja Kallas said member states have "no appetite" to extend the Aspides Red Sea mission to the Strait of Hormuz. This is not the scaling-up of allied participation that optimists predicted would happen when the stakes got high enough. It is the opposite.

This point deserves emphasis because it directly contradicts a common assumption—that European nations with economic exposure to Suez disruption would naturally step up during wartime. During the 2024 Houthi crisis, the EU launched Operation Aspides, which seemed to validate that logic. But Aspides was a limited defensive mission during a period when the Houthis were attacking shipping but the US was not at war with Iran. The moment the US launched a war that Europe didn't start, wasn't consulted on, and doesn't support, the calculus inverted. Economic pain from closed trade routes is not translating into military participation. It is translating into resentment.

The timing problem is the killer. Even if strikes against Iran do eventually degrade the Houthi resupply pipeline (and there is a logical case for this), the effect operates on a delayed timeline. The Houthis have been accumulating weapons for nearly a decade. A 750-ton weapons shipment was intercepted heading to the Houthis from Iran just last June—months after both US and Israeli bombing campaigns had supposedly degraded their capacity. A Foreign Policy analysis from earlier this month noted that the Houthis' Red Sea campaign "consumed their best weapons systems" but also found that the group retained stockpiles and that "seekers, guidance electronics, and engines remain the bottlenecks" requiring imports. The Soufan Center reported that the Iran war itself has impeded weapons flow because "Iran needs its remaining missile and drone stockpile" for its own defense. That's a real constraint. But the Houthis have adapted before—their July 2025 attacks used coordinated "wolf pack" tactics with skiffs, explosive drone boats, and limpet mines alongside missiles. They don't need precision-guided weapons to sink undefended merchant ships in the narrow Bab al-Mandeb strait.

The strongest counterargument is that the Houthis have in fact shown restraint for a full month since the Iran war began, and that this restraint reflects a rational calculation that entering the war would be costly. The Soufan Center reported that Houthi leaders fear Israeli decapitation strikes like the one in August 2025 that killed most of the Houthi cabinet. They have domestic concerns, including a southern secessionist threat. They struck a deal with Trump in May 2025 and may not want to burn that goodwill entirely. I take this seriously. The Houthis are not suicidal, and they have shown they calibrate their actions based on political timing rather than pure military opportunity.

But Saturday's missile attack changes the calculus. They have now entered the war. And the Houthis' stated red lines—that the US and Israel not use the Red Sea for attacks on Iran, that no new countries join the war, and that escalation against the "Axis of Resistance" not continue—have arguably all been crossed. Axios reported yesterday that the Houthis have "yet to use their nuclear option of closing the strait of Bab al-Mandeb" but that this remains their most potent escalatory tool. If the war continues, and the Houthis escalate from missiles-at-Israel to attacks-on-shipping, we will be right back where we were in 2024—except with the Strait of Hormuz already closed, meaning the Red Sea is the last functioning bypass route for millions of barrels of oil. Shutting both would be catastrophic.

Trump has said the Iran campaign would be over in four to six weeks. Secretary Rubio said "weeks, not months." We are now at day 29. Iran has rejected the US 15-point peace plan. The IDF chief of staff has warned that the military is under "severe strain" with multiple fronts open. Trump is moving thousands of additional troops to the region while simultaneously claiming victory. This is not the trajectory of a war that ends on schedule.

I think the evidence strongly supports a conclusion that the Houthi front, if activated for maritime attacks, will extend this conflict well beyond any promised timeline and impose costs the current force structure cannot absorb without unacceptable tradeoffs elsewhere. The Pentagon doesn't need to "solve" Yemen—but managing it requires naval assets it is already burning through at an unsustainable rate.

Here is what I'd watch in the coming days and weeks: First, whether Houthi attacks expand from missile strikes on Israel to attacks on Red Sea shipping. That is the real escalatory threshold. Second, whether the US can reconstitute the Gerald R. Ford quickly enough to maintain three-carrier operations, or whether mechanical issues force a period of reduced capacity at exactly the wrong moment. Third, whether any major European navy commits assets to Red Sea defense or Hormuz escort—so far, the answer is a resounding no. And fourth, whether Iran can continue resupplying the Houthis during an active war. A second 750-ton weapons interdiction would suggest the pipeline is still flowing; continued absence of such seizures might indicate it has been meaningfully disrupted.

My prediction: the Houthis will resume Red Sea shipping attacks within two weeks. When they do, the Pentagon will face a resource allocation crisis that no amount of claims about "containment" can paper over. The war that was supposed to be over in weeks will instead have an open-ended southern front with no exit criteria, no allied support, and a cost structure that grows more unfavorable with every interceptor fired. That's not a sideshow. That's the defining constraint of this entire campaign.
