Reports of Iran's potential inclusion in the Mecca Joint Defence Agreement have raised questions about the broader direction the emerging coalition could take. Joining the alliance could transform a nascent mutual-defence arrangement into the foundation of a wider regional security framework.
Mehdi Rahimi, director of the Iranian parliament's news agency, noted that the country's leadership was reviewing the proposal and contended that establishing a regional security framework would constitute a gain for Iran. Not long after, Esmail Baghaei, a spokesperson for the Iranian Foreign Ministry, clarified that Tehran had not been extended any official invitation, though the possibility of dialogue with the agreement's member states on shared regional security arrangements had been put forward.
At present, the move appears to be a diplomatic gesture aimed at gauging how the various parties respond, rather than the launch of any formal accession procedure. According to that reading, the pact is designed not to target Tehran as an adversary, but to establish a regional security framework in which Iran would be a participant.
On August 7, the Mecca Agreement was formalised with the signatures of Crown Prince Mohammed bin Salman of Saudi Arabia, President Recep Tayyip Erdoğan of Turkey, and Prime Minister Shehbaz Sharif of Pakistan. The treaty's core clause holds that a hostile act targeting any one signatory nation is treated as an assault upon all members collectively.
The arrangement would, in principle, draw on complementary assets from three countries: Saudi Arabia's vast wealth and leverage over global oil supply, Türkiye's sizeable armed forces and developed defence manufacturing sector, and Pakistan's extensive military experience and nuclear capabilities. The communiqués, however, outline no structured process for reaching decisions and leave unaddressed the specific obligations each signing party would bear in the event of a crisis. The agreement currently functions as a shared political commitment to deterrence rather than a formal defence alliance.
Trump endorsed the agreement and indicated his approval that nations in the area were taking on a larger share of responsibility for their own security. The position aligned with a view he had held for some time — that partner nations ought to take on a greater portion of defence spending, freeing the United States from both the financial burden and the obligation of serving as an open-ended security guarantor for other countries.
Analysts have pointed to the Mecca Pact as the most concrete institutional development yet showing that neighbouring states have moved toward building independent power structures rather than relying solely on external security guarantees, though they note it may not represent the first indication of a shifting balance in the region. While the United States retains its military bases, weapons systems, intelligence networks, and relationships with influential regional actors, analysts have questioned whether its once-dominant role in shaping Middle Eastern security arrangements remains as unchallenged as it once was.
The military conflict between the United States and Israel on one side and Iran on the other hastened that shift by exposing the contradictory dimensions of American security commitments. Missile attacks attributed to Iran, along with interference with maritime commerce and vulnerabilities in energy supply networks, illustrated that an alliance with Washington offers nations in the region only partial protection against external pressures.
The three founding member states are maintaining their defence procurement and diplomatic relationships with the United States while also seeking independent frameworks that can operate when their interests and Washington's priorities do not align.
Extending an invitation to Iran offers the alliance's three founding members a way to head off a dispute that could otherwise escalate into a fresh point of contention. Should Tehran remain outside the agreement, the three-way pact between Saudi Arabia, Türkiye and Pakistan may be interpreted by Iran as an attempt to establish a Sunni security bloc directed against it.
Granting Tehran membership in the grouping has shifted the alliance's central debate away from identifying adversaries and toward determining what norms its dominant regional powers are willing to observe. Regardless of whether Iran participates, the ongoing talks themselves lower the probability that the accord will function as a tool for excluding it.
The arrangement positions Saudi Arabia to balance military deterrence with ongoing diplomatic outreach, reinforces Türkiye's standing as a neutral broker, and allows Pakistan to preserve ties with both Riyadh and Tehran without being forced to take sides. Broader Iranian involvement in the agreement could alter its fundamental character. The arrangement would no longer function as a coalition of states bound by shared interests, but rather as a framework of collective constraint in which no member's protection could be pursued at the expense of another's exposure.
A mutual defence commitment alone would not be sufficient to address the full scope of what is involved. Agreed protocols under discussion would cover urgent lines of communication, procedures to avert military incidents, systems for sharing data on missile activity, guarantees of free passage at sea, and pledges to refrain from backing armed aggression against fellow signatories.
Addressing the militia factions with ties to Iran was expected to pose the greatest challenge. Should Tehran become party to the agreement, there would likely be an expectation that it bear accountability for the conduct of armed groups receiving its weapons and backing. Concurrently, the remaining parties would face an expectation to avoid capitalising on fractures within Iranian society as a tool for pressuring its government. Analysts have described mutual exchange of this kind as the means by which an attractive framework could be transformed into a workable arrangement across the region.
Joining the group could open pathways for Iran toward both political engagement and broader economic participation, given that the region's growth has historically been held back not by insufficient resources, but by prolonged instability. Armed conflict tends to drive up maritime insurance premiums, push states toward military stockpiling, deter long-term capital allocation, and transform transit routes into tools of geopolitical leverage.
The financial resources of Saudi Arabia, Turkey's manufacturing base, Pakistan's consumer market, and Iran's energy reserves and transit corridors each hold potential for mutual reinforcement. Joint engagement between the parties holds the potential to establish trade and transit corridors linking Central Asia, the Persian Gulf, the Mediterranean, and the Indian Ocean, while governance of the Strait of Hormuz could shift from a tool of reciprocal pressure into a matter of common strategic interest.
Ongoing sanctions on Iran, rivalries over transit corridors, diverging ambitions between Turkey and Saudi Arabia, and longstanding tensions between Pakistan and India all carry the potential to introduce pre-existing regional disputes into the emerging framework. Among the external challenges ahead, the future ties between the Mecca Pact and Israel stand out as a particularly unresolved question.
Israel has expressed reservations about the agreement and may view any Iranian membership as a threat to its regional position. Should the alliance's members clearly define the accord as defensive in character and extend to Israel assurances aimed at averting hostilities, the arrangement may serve to limit escalation rather than lay the groundwork for it. Greater clarity on the matter is expected following the Knesset vote set for 27 October 2026.
Should Netanyahu and his coalition retain office, regional friction could escalate, particularly given ongoing Israeli military operations against Iran and Syria alongside a posture that views Türkiye's expanding role as a potential challenge. A prospective governing alliance could prioritise diplomatic accommodation over sustained hostilities, seeking to integrate Israel into a reconfigured regional order.
The Mecca Agreement represents a stated commitment to regional change rather than an established new order in the Middle East. Should the organisation succeed in integrating Iran as a member, establishing shared norms of restraint, and reaching a stable arrangement with Israel, the region's states could find themselves with a collectively built security framework for the first time in many decades.
