Half a Year Into Iran Conflict, Gulf Security Framework Begins to Shift

Six months into the Iran conflict, it is worthwhile to take stock of what has actually shifted across the Gulf.

Following Iran’s June 2025 missile strike on Al Udeid Air Base in Qatar, I warned that the coming years would be more dangerous for the Gulf and that deeper defense cooperation and integration would become unavoidable. Earlier this month I noted that the Gulf can no longer depend solely on its traditional security toolkit and must develop a more indigenous security ecosystem. So far, events have confirmed the general thrust of both points.

Over the past six months it has become evident that the war is doing more than altering defense budgets or spawning new security pacts. It is reshaping how Gulf states conceive of security—determining whom they should partner with, what they should expect from those partners, and what cooperation ought to look like when a crisis erupts.

Some of these shifts are apparent. The conflict has starkly revealed the susceptibility of cities, energy facilities, airports, ports, and shipping lanes to missiles, drones, and other disruptive means. Threats once confined to tabletop exercises and planning documents have turned into pressing operational challenges.

For decades, Gulf security has been anchored by a familiar pattern: the United States supplied the primary external security shield, Gulf states upheld bilateral ties with Washington and other Western capitals, and the GCC offered a regional framework where defense integration remained patchy.

That pattern has not vanished, nor should it. The United States remains essential to Gulf security and will continue to play a central role for the foreseeable future. What is evolving is the belief that this arrangement alone suffices.

The conflict has hastened the shift toward a more layered security architecture. Gulf states are bolstering intra‑regional cooperation while expanding ties with a broader set of partners. Turkey is growing in significance. European nations now have a greater chance to assume an operational role. Long‑standing bilateral military ties are being called upon to do more, and novel regional mechanisms are emerging alongside the established ones.

A prominent recent illustration is the Mecca Joint Defence Agreement among Saudi Arabia, Turkey, and Pakistan. Its stipulation that an armed attack on any one member be regarded as an attack on all has naturally drawn parallels with NATO.

The underlying principle is not novel to Gulf security. The GCC’s own Joint Defence Agreement already treats an attack on one member as an attack on all, a pledge that GCC members have repeatedly reaffirmed throughout the current war. The Mecca accord differs in that it extends this collective‑defense concept beyond the GCC, binding Saudi Arabia to Turkey and Pakistan.

While the NATO analogy is understandable, it can also obscure the real developments. The Gulf does not need to replicate NATO, and the broader Middle East is ill‑suited to a monolithic security alliance predicated on a single hierarchy and a uniform threat perception.

The threat confronting a Gulf state may be a state actor one day and a non‑state actor the next. Nations that share a similar view of one threat may diverge sharply on another. Moreover, no regional state, however capable, is likely to be embraced as the enduring political and military leader of every conceivable coalition.

Instead, what is taking shape is a network of overlapping partnerships rather than a single grand alliance. Various countries will collaborate against distinct threats—some arrangements will be Gulf‑led, while others will incorporate regional or Western partners.

This model also demands a revised conception of leadership. A regional security framework predicated on a fixed hierarchy will inevitably encounter resistance, as Gulf and Middle Eastern states guard their sovereignty and contribute disparate capabilities.

Leadership ought to follow the threat. The state confronting the immediate danger should hold the primary political voice in defining response objectives, acceptable escalation levels, and the use of its territory. However, operational leadership does not have to mirror the political hierarchy.

A maritime crisis might be best managed by the partner possessing the strongest naval capability, whereas an air‑defense crisis could necessitate the partner with the most relevant assets assuming a larger operational role.

Such flexibility may be the sole realistic foundation for deeper security cooperation, but it hinges on whether these overlapping relationships can effectively link up when required.

This is where interoperability becomes crucial. If several nations pledge mutual support in a crisis, can they actually deliver? Can they exchange information swiftly, communicate across their militaries, synchronize decisions, and know beforehand who is authorized to act?

An attack on one nation does not obligate every partner to respond identically. Support may manifest as intelligence sharing, air defense, logistics, maritime protection, or, in the gravest scenarios, direct military action. The clearer these expectations are established beforehand, the more credible the commitment proves when a crisis arises.

Concrete examples already show what deeper integration can resemble without a large regional institution. Qatar’s military partnership with Britain has transcended the classic buyer‑seller dynamic; British and Qatari personnel have trained and flown Typhoon aircraft together within the joint squadron, and Qatar and Turkey have established a combined military command structure.

These arrangements existed prior to the current war. The UK‑Qatar partnership, however, was also put to the test during it: in March, an RAF Typhoon flying with the joint squadron intercepted and downed an Iranian attack drone aimed at Qatar.

Integration need not commence with a treaty signed by ten nations; sometimes it starts with two militaries learning to operate effectively together.

Europe can assume a larger role without supplanting the United States. Washington will likely stay the Gulf’s foremost security partner, even as Gulf states forge deeper operational ties with Britain, France, Turkey, and other capable allies.

The past six months have bolstered the argument for this approach. Gulf and European militaries are increasingly confronting similar operational challenges—missiles, drones, maritime insecurity, electronic warfare, and threats to critical infrastructure. Consequently, the next phase of Gulf‑European defense relations should be evaluated less by the monetary value of signed contracts and more by the ability of their forces to cooperate when circumstances demand it.

That entails more exercises, embedded personnel, joint planning, and mechanisms that enable bilateral partnerships to link with broader GCC and regional frameworks.

The Mecca accord will undergo the same evaluation. Turkey’s defense ministry has indicated that the three nations intend to pursue political and military coordination, joint exercises, air‑defense cooperation, and deeper defense‑industrial ties.

For the moment, however, these remain plans rather than proof of operational integration. The agreement’s ultimate significance will hinge on whether Saudi, Turkish, and Pakistani forces cultivate habits of cooperation—namely, the ability to share intelligence, coordinate air defense, sustain joint operations, and leverage defense‑industrial collaboration to solve practical military challenges.

Six months into the Iran conflict, then, the contours of a new Gulf security architecture are beginning to emerge.

It is unlikely to comprise a single alliance, a sole leader, or a monolithic threat definition. Nor is the Gulf discarding the United States or dismantling the security relationships that have served it for decades. Instead, a more flexible system is coalescing around those existing ties: stronger Gulf‑internal cooperation, additional regional partnerships, deeper links with European militaries, and heightened focus on whether states can genuinely operate together.

Some of this momentum could wane if the immediate threat subsides. The challenge now is to ensure the lessons of the past six months endure. Ultimately, the test is straightforward: when the next missile is launched, the next drone breaches a border, or the next shipping lane comes under threat, can the involved states perceive the danger collectively, decide together, and respond in unison?

If they can, then the war’s most significant legacy may not be another treaty or alliance. It could signal the inception of a Gulf security system that is more interconnected, more adaptable, and better attuned to the region it is meant to safeguard.
