Here is the strange part. After three years of the cycle that has defined the Middle East — the threats, the strikes, the retaliations, the proxies lighting up the map, the tankers seized, the airports closed, the markets convulsing every Friday afternoon — there is now, genuinely, a ceasefire on the table. Not a rumour. Not a leak. An actual document. Drafted in Muscat, refined in Rome, blessed quietly by the Saudis and the Emiratis, and currently sitting on two desks: one in the Oval Office and one in the office of the Supreme Leader. By the end of next week, depending on who you believe, either everyone signs or everyone walks away and we go straight into another summer of brinksmanship.
So the obvious question, which every defence ministry, oil trader, shipping line, sovereign wealth fund, and insurance underwriter on the planet is asking right now: does this one actually hold?
The honest answer is more interesting than yes or no. Let us walk through it.
Forget the headlines for a second. The text matters. What has leaked, and what is being confirmed off-record by people close to both delegations, is that this is not a comprehensive deal. It is a sequenced one. Phase one is a 90-day cessation of kinetic activity across all theatres — the Gulf, the Red Sea, southern Lebanon, western Iraq, eastern Syria, and the airspace over Iran itself. Phase two, which only triggers if phase one holds, is the partial unwind of the sanctions package that has strangled Iranian oil exports since the early Trump years. Phase three, which only triggers if phase two holds, is the framework for the broader political settlement — the nuclear file, the proxies, the regional posture.
In other words, what governments are about to sign is not peace. It is a 90-day audition for peace, with the right of either side to walk away if the other one cheats. That is much smaller than the headlines suggest, and it is also, frankly, the only kind of deal that ever holds in this region. The 2015 JCPOA tried to do everything at once and the political coalition that signed it could not survive the next election cycle. This one is being designed to survive its first hostile news week. That is progress.
Anyone tempted to assume Trump will torpedo this for theatrical reasons should look harder at the politics. He has spent the last six months telegraphing — loudly, on every available platform — that he wants to be the president who ended the Middle East war. Not paused. Ended. He has an election cycle behind him, a second-term mandate that needs a foreign-policy headline, and a domestic audience that is genuinely tired of cruise-missile economics. He also has the only piece of leverage that has ever moved Tehran: the credible threat that if they walk, the Pentagon will not be restrained the way it was during the Biden years. That combination — a president who wants the win, an administration willing to use the stick, and a counterparty that has run out of cheap escalations — is the most favourable backdrop for a deal in two decades.
The question is not whether Trump wants the ceasefire. He clearly does. The question is whether he can hold his coalition together long enough to deliver phase two. The Israeli government is openly opposed. A wing of his own party is opposed. The Saudis are publicly supportive and privately nervous. The Emiratis are quietly enthusiastic, which is the closest thing to a green light Washington gets from Abu Dhabi. Our earlier read on what to realistically expect from the Trump–Iran track still holds: this is a president who is willing to spend political capital on a deal, but only one that lets him claim victory immediately.
The change in tone from Tehran over the last three weeks is not a Western imagination. Araghchi has stopped saying things that make a deal impossible. The Supreme Leader's recent public addresses have skipped, conspicuously, the standard rhetorical attacks. The IRGC has been kept out of the negotiating posture in a way that is unusual to the point of being unprecedented. And, most tellingly, the Iranian oil ministry has begun preparing the export infrastructure for a sanctions unwind that, officially, has not yet been agreed.
The reason is not a sudden ideological pivot. The reason is arithmetic. Iran's economy is in the worst shape it has been in since the early 1990s. The currency is shredded. The middle class is gone. The IRGC's revenue streams, which depend on regional projection, have been cut by the simultaneous degradation of the proxy network, the loss of Syrian logistical depth, and the maritime pressure on the smuggling routes. The state needs a sanctions unwind the way a patient needs oxygen. They will not say so publicly. But every signal from inside the system says they are willing to pay a price for it that would have been unthinkable two years ago.
That said — and this is where the honest answer earns its honesty — Tehran has reached this point before. Twice. In 2015 and again in 2022, the regime made tactical concessions that it later walked back the moment the domestic political wind shifted. The discipline required to hold a 90-day cessation, when every faction inside the Iranian system has an incentive to break it, is exactly the discipline that the Islamic Republic has historically lacked. The proxies are the obvious flashpoint. One Houthi missile, one Kata'ib Hezbollah convoy, one IRGC-trained drone team in the Iraqi border zone — and the ceasefire is dead before it has matured. The question is whether Tehran can actually control the network. The honest answer, drawn from a sober look at how that proxy network actually functions, is that they can control most of it most of the time, but not all of it all of the time. And the deal needs all of it, all of the time.
The most interesting movements right now are happening in places that do not produce cable-news segments. The Saudi defence ministry, the UAE air force, the Qatari logistics command, and the Omani back-channel team have spent the last two weeks running through scenarios for what each phase of the deal means for their own posture. None of them are taking down their air defences. None of them are slowing their procurement. The Saudi 50 per cent localisation drive has, if anything, accelerated. The UAE just signed off on a fresh interceptor order that will not be delivered until 2028. These are not the decisions of governments who think the war is over. They are the decisions of governments who think the war may pause and resume, and who want to be ready for either outcome.
That is the Gulf playbook, and it is the right playbook. The Gulf monarchies have learned, expensively, that the moment you confuse a ceasefire with a settlement is the moment you get caught short by the next escalation. The structural shift in regional procurement after the Red Sea crisis was a direct response to the realisation that the security environment in this part of the world does not move in straight lines. It moves in cycles. You arm for the cycles, not for the headlines.
If the deal collapses — and there is at least a 35 per cent chance it does — it will be for one of four reasons. The first is an Israeli action that Tehran cannot ignore. A strike inside Iran, an intelligence operation that produces visible casualties, a southern Lebanon escalation that the IRGC feels compelled to answer. The Netanyahu government has every incentive to find a way to make the ceasefire impolitical, and the operational capacity to do so.
The second is a proxy that goes off-script. The Houthis are the most likely actor here. Their incentives are not Tehran's incentives. They have a domestic political logic in Sanaa that does not always align with the strategic calculations in Tehran, and they have demonstrated repeatedly that they will fire when they feel they need to, ceasefire or not.
The third is a US domestic political event that forces Trump to walk away. A terrorist attack with an Iranian connection. A leaked intelligence assessment that embarrasses the negotiating team. An election-year congressional resolution that boxes the White House in. None of these are predictable. All of them are possible.
The fourth, and the most underrated, is a Saudi or Emirati decision that the deal as drafted is unsafe. The Gulf is not a passive observer in this process. If Riyadh or Abu Dhabi conclude that the sanctions unwind in phase two will refuel the IRGC's regional projection, they will quietly use every lever they have — and there are many — to delay or dilute it. They have done it before. They will do it again if they need to.
If the deal holds — and there is at least a 50 per cent chance it does, which is the highest that number has been in nearly four years — it will hold for one of three reasons. The first is that Trump, against every prior expectation, manages to keep his coalition aligned through the first hostile news cycle. That requires him to absorb domestic political pain in exchange for foreign-policy credit, which is something he has done before when the credit is large enough.
The second is that Tehran enforces discipline on the proxy network with a seriousness it has not shown in two decades. There are early signs this is happening — the recent quiet recalls of senior IRGC-Quds officers from Iraq and Lebanon are not random — but the test comes the first time a proxy commander decides his local political logic overrides Tehran's strategic logic.
The third is the one almost no one is talking about: that the Gulf, which has the most to lose from a failed ceasefire and the most to gain from a successful one, becomes the active stabiliser of the process. Saudi and Emirati diplomatic capacity, paired with Omani back-channel infrastructure, is the only force in the region capable of catching the deal when one of the principal parties wobbles. If the Gulf decides this ceasefire is in its interest to defend, it will be defended. That is the variable to watch.
Here is the misconception worth correcting. A successful ceasefire does not end the defence procurement cycle. It does not even slow it meaningfully. Our earlier note on whether countries will keep arming if the war ends walked through this in detail, and the conclusion has not changed. The structural drivers of the current procurement supercycle — NATO restocking, Indo-Pacific buildup, Gulf modernisation, the new entrants from Africa and Latin America — are not contingent on Iran. They are contingent on the lessons that have been learned over the past four years about what modern war actually costs and what modern deterrence actually requires. Those lessons do not unlearn themselves because a ceasefire is signed in Muscat.
What changes, if the ceasefire holds, is the composition of the demand. Less emergency procurement, more long-cycle modernisation. Less ammunition restocking under panic conditions, more deliberate replenishment with precision-guided variants. Less expeditionary posture, more home-base air defence. The cycle stays. The character shifts. That is the practical takeaway for anyone trying to plan a procurement strategy through the back half of 2026.
So — does this ceasefire end the war?
The honest answer is that this ceasefire ends the active phase of the war. It does not end the conflict. The conflict is structural and will continue to define the security environment of the Middle East for years. But the active phase — the strikes, the proxies hot, the tankers seized, the airspace closed — has a real chance of ending here, and that real chance is higher than it has been at any point since 2022.
The probability the ceasefire is signed is high. The probability it holds for 90 days is roughly even money. The probability it survives long enough to mature into phase two is lower than that, but not by much. And the probability of a permanent, comprehensive settlement is still low — perhaps one in five, on the most optimistic read. None of those numbers are zero. None of them are certain. The headline will be ambiguous, the small print will be technical, and the only honest framing is this: we are closer to the end of the active phase than we have been in years, and the smartest thing anyone in the defence sector can do is plan for the deal to hold while remaining fully prepared for the day it does not.
The cameras will tell you it is over. The cycle will tell you it is paused. The Gulf is acting like both can be true at the same time. That is the right posture. The next ninety days will tell us which one it actually was.
