Two days after Mohammed bin Salman, Recep Tayyip Erdogan and Shehbaz Sharif signed the Mecca Joint Defense Agreement, a drone hit Aramco’s refinery at Jizan and started a fire. The Saudi energy ministry confirmed the blaze on the morning of August 9, said it had been extinguished, and reported no casualties. The Houthi military spokesman claimed the strike and called it precise. Nobody in Ankara or Islamabad was asked to do anything about it, and nobody was going to be.
That gap, 48 hours between the signing ceremony and the strike, is the most useful thing to have happened in the Gulf this month. It shows exactly what the pact is for, and what it cannot touch.
The pact is denominated in the wrong currency
The Mecca agreement says that an armed attack on any of the three signatories is an attack on all of them. Commentary since August 7 has focused on the aggregate: roughly 1.4 million active personnel, 3,400 aircraft, 6,000 tanks, more than 340 naval assets. NATO’s second-largest army, the world’s largest oil exporter, the only nuclear-armed Muslim state.
None of that inventory is relevant to the threat currently landing on Saudi territory. Tanks do not intercept drones. A nuclear deterrent does not deter a movement that has already absorbed seven years of Saudi airpower and a seven-week American bombing campaign, and concluded from both that it can keep going.
There is also precedent, and it is not encouraging. Saudi Arabia has had a mutual defense treaty with Pakistan since September 2025 and a collective defense arrangement with the GCC states since 2000. Neither has ever produced anything resembling an Article 5 response. What the Mecca text adds is a third signature and a holy city, which is symbolism, and symbolism has its uses, but it does not put interceptors over Jizan.
What the Houthis are actually doing
Since declaring a maritime blockade of Saudi Arabia on July 20, the Houthis have run a campaign that is cheap, legible and hard to answer. ACLED counted sixteen attacks on Saudi assets between July 13 and August 14: seven oil facilities and six tankers among them. Najran airport on August 4. The tanker Wafa off Yanbu on August 5. Jizan on August 9. Two more drone attacks on Najran province on August 20.
Yanbu matters more than the others. It sits about a thousand kilometres north of Yemen, which means range has stopped being a constraint on this campaign. The Houthis have framed all of it as a siege answering a siege, a direct trade against the Saudi-enforced restrictions on ports and airspace in the territory they hold. That framing tells you the objective. This is not an attempt to defeat Saudi Arabia militarily, which the Houthis cannot do and have never claimed they could. It is an attempt to make the Red Sea coast expensive enough that Riyadh pays to make it stop.
The coast is where Saudi Arabia has been putting its future. Yanbu and Jizan are export and refining infrastructure; NEOM and the wider Vision 2030 build-out sit on the same water. An insurgent group with a few hundred kilometres of coastline and a workshop economy has found the one place where cheap munitions meet expensive assets, and it is hitting there on purpose.
What Ankara and Islamabad can actually supply
The pact does have content, but the content is industrial rather than operational. Turkey brings drones, missiles, sensors, electronic warfare and naval systems from a defense industry that has spent a decade learning to build them at volume. Pakistan brings manpower, training and the ability to supply things like 155mm shells at scale. Both matter more than usual right now because Western export approvals have become unpredictable, and Riyadh has been looking for suppliers who will not attach conditions or delay deliveries during a shooting war.
Pakistan has reportedly already sent troops and air defense to the kingdom. That is real, and it is more relevant to Saudi security this month than the treaty language is. But it is a procurement relationship with a security wrapper. It changes what Saudi Arabia can buy and how fast. It does not change the arithmetic of a one-way drone against a refinery, which is the arithmetic that is currently beating the kingdom.
Iran has noticed this. An IRGC statement on August 20 said Riyadh would be unable to contain the Houthis, and a member of the Iranian parliament made the sharper point earlier in the month: paper agreements with Turkey and Pakistan will do for Saudi Arabia roughly what decades of dependence on Washington did for it. That is propaganda, and it is also correct about the specific problem.
The exit runs through Muscat
While Riyadh signs deterrence agreements in Mecca, it is reportedly talking to the Houthis through Oman, which brokered the end of the American air campaign in May 2025 and has been the channel of choice for a decade. Saudi officials deny the talks. The denial is consistent with there being talks.
The alternative on the table is worse. Riyadh has been weighing a ground operation fronted by Yemeni government forces, which is the same theory of victory that failed between 2015 and 2022, attempted now with a government that took the south from the Southern Transitional Council only in January and has not resolved anything with the STC since. The STC retains its forces and its support base. A northern offensive that pulls government units away from the south is an invitation for that file to reopen, and a two-front Yemen would end Saudi freedom of action entirely.
Oman is also the mediator on the Strait of Hormuz interim arrangement with Iran. The same small state now sits on both of the region’s active maritime chokepoint files. If Riyadh gets out of this in the next quarter, the venue will be Muscat, and the price will be some version of lifting the restrictions the Houthis have been calling a siege since July.
Indicators worth tracking
Watch for a pause in strikes on Saudi territory that is not matched by a pause inside Yemen, which would indicate a bilateral understanding taking shape while the civil war continues. Watch Saudi air movements over Saada and Hodeidah, since the Houthis have tied each round of retaliation to claimed airspace violations there. Watch whether Yemeni government forces mass toward Marib or the Red Sea coast rather than trading fire in place. Watch the STC. And watch whether Turkish or Pakistani air defense equipment shows up in the southern Saudi provinces, which would be the first evidence that the Mecca agreement has produced anything more than a photograph.
The pact answers a question Saudi Arabia may face later. The drones are a question it faces now.
