The Houthis have spent years as a regional irritant. They are now a systemic threat to global energy markets. Their seizure of the Yemeni port of Mocha and several Red Sea islands gives them operational control over the Bab al-Mandeb strait — a chokepoint carrying roughly 12 percent of global oil trade. Combine that with drone and missile strikes on Yanbu, home to Saudi Arabia's critical East-West Pipeline capable of moving up to seven million barrels a day, and you have a group that can credibly threaten two of the world's three most important oil transit routes simultaneously. France's response — soldiers, radars, and defence systems dispatched to Yanbu — is notable for what it reveals about Riyadh's own defensive gaps. Macron framed it as protecting infrastructure "not to involve ourselves in any conflict," but French troops guarding a Saudi oil terminal is involvement by any operational definition. The deployment signals that Saudi air defences, despite intercepting six ballistic missiles on Thursday alone, cannot guarantee the safety of fixed industrial assets without allied reinforcement. The Mecca Joint Defence Agreement meeting between Saudi, Pakistani, and Turkish foreign ministers is the diplomatic headline, but its operational significance remains uncertain. The pact treats an attack on one member as an attack on all — NATO's Article 5, Gulf edition — but it has never been formally triggered, and both Pakistan and Turkiye are simultaneously working as mediators in the broader Middle East conflicts. Their utility as military allies and their credibility as peacemakers are in direct tension. The energy market arithmetic is unforgiving. Saudi Arabia had been using the East-West Pipeline to route crude exports around the Strait of Hormuz, which is restricted amid the US-Iran war. The Houthis have now disrupted that workaround, forcing some Saudi exports back through the very chokepoint Riyadh was trying to avoid. This creates a double vulnerability: both the Red Sea and the Persian Gulf routes are now contested. Brent crude briefly topped $108 a barrel on Thursday before settling to $105.77 — and Sparta Commodities analyst June Goh projects oil will stay above $100 as long as the Iran conflict continues, with global inventory gaps widening. The United States is conspicuously absent from direct military involvement, though Saudi Foreign Minister Prince Faisal bin Farhan Al Saud confirmed ongoing partnership. This absence shifts the burden to a coalition of the willing — France, Pakistan, Turkiye — none of whom have the force projection capabilities the US Navy would bring to a Red Sea chokepoint fight. The gap between what the situation requires and what these allies can deliver is the story's central tension. Saudi Arabia's grand mufti calling on soldiers to lay down their lives against the Houthis underscores how seriously Riyadh takes the escalation. But rhetoric is not strategy. The kingdom's decade-long military campaign against the Houthis produced a stalemate, not a victory. The Houthis are now better armed, better positioned, and fighting in a context where Israeli operations against Hamas and Hezbollah — and the US war on Iran — give them ideological momentum and operational cover. At the UN General Assembly, Yemen's vice president warned the Houthis were "taking hostage the entire global economy." That framing is hyperbolic but structurally correct: a non-state actor now controls enough geography to impose a tax on 12 percent of global oil trade and threaten the infrastructure that moves the rest. Every consumer on Earth is paying that tax at the pump.
