The February 2026 conflict between the United States, Israel and Iran marked a decisive rupture in the regional security landscape. Strikes that began on 28 February triggered Iranian retaliation across the Gulf, disrupted maritime traffic through the Strait of Hormuz and accelerated existing doubts about the reliability of external guarantees. In the months that followed, middle powers moved quickly to explore new forms of coordination. Foreign ministers from Türkiye, Egypt, Pakistan and Saudi Arabia held a series of meetings in Riyadh, Islamabad, Antalya and Cairo. These gatherings produced joint statements on regional stability and expressed support for Pakistani mediation efforts. The 2025 Saudi-Pakistani Strategic Mutual Defence Agreement was invoked during the fighting, with Pakistani forces deployed in support of the Kingdom.
The long-standing bargain that underpinned Middle East security for decades has eroded steadily. Successive US administrations signalled reduced commitment through the 2003 Iraq invasion, the 2015 nuclear deal with Iran, the 2021 Afghanistan withdrawal and a transactional approach to partnerships. The 2026 war crystallised these trends. American and Israeli objectives focused on degrading Iranian nuclear and missile capabilities and targeting leadership. The campaign achieved tactical effects yet produced strategic spillovers that affected Gulf states directly. Iranian missile and drone strikes reached targets in Saudi Arabia, the United Arab Emirates and elsewhere. The temporary closure or severe restriction of Hormuz traffic generated global economic consequences and exposed the vulnerability of energy-dependent economies.
Gulf leaders had warned of precisely such outcomes. The war therefore reinforced perceptions that reliance on a single external guarantor carries unacceptable risks. At the same time, the conflict did not eliminate Iranian capabilities. Tehran retained significant missile stocks and proxy networks, even as it suffered leadership losses and industrial damage. Reconstruction and reconstitution efforts began during the April ceasefire and continued after the June memorandum of understanding. These developments left regional states facing a more complex threat environment. They also created political space for indigenous initiatives.
The five states under consideration bring complementary strengths that could, in principle, support greater collective resilience. Pakistan possesses the region’s only acknowledged nuclear arsenal, estimated at approximately 170 warheads. Its delivery systems include road-mobile ballistic missiles with ranges exceeding 2,500 kilometres and a developing sea-based component. The army maintains roughly 660,000 active personnel and possesses extensive combat experience. Saudi Arabia contributes substantial financial resources, with defence expenditure exceeding 78 billion US dollars in 2025, together with advanced platforms acquired from Western suppliers. Its geographic position gives it influence over key maritime routes.
Türkiye fields NATO’s second largest military and has developed a significant indigenous defence industry. Combat-proven unmanned aerial systems, the Altay main battle tank programme and the KAAN fifth-generation fighter project demonstrate growing technological autonomy. Egypt maintains the largest Arab conventional force, with approximately 440,000 active personnel. Its control of the Suez Canal confers strategic leverage, while decades of operations with equipment from multiple suppliers have produced a battle-hardened military. Qatar, though smaller in population and territory, offers sovereign wealth funds exceeding 500 billion dollars, modern airbases and advanced fighter aircraft disproportionate to its size. Its diplomatic experience in mediation adds a distinct capability.
Aggregate figures are impressive. Combined population surpasses 500 million. Defence spending across the group exceeds 150 billion dollars annually when measured in recent budgets. Manpower, armoured formations and aircraft inventories are substantial. These resources provide a foundation for enhanced deterrence, improved air and missile defence coverage and greater industrial self-reliance. Individually, however, none of the states can field a complete spectrum of capabilities spanning nuclear deterrence, integrated air defence, maritime security and advanced command systems. Pooling therefore offers logical efficiencies.
Real-world cooperation has already moved beyond rhetoric. The Saudi-Pakistani Strategic Mutual Defence Agreement, signed in September 2025, contains language that treats aggression against one party as aggression against both. During the 2026 conflict Saudi Arabia invoked the pact. Pakistani deployments, including ground forces, aircraft and unmanned systems, followed. Parallel diplomatic activity produced the so-called R4 or quadrilateral process. Foreign ministers of Türkiye, Egypt, Pakistan and Saudi Arabia convened four times between March and June 2026. Meetings addressed support for mediation, regional stability and potential security coordination. Qatar participated in some broader Islamic and Arab consultations that overlapped with these efforts. These gatherings represent the most sustained institutional dialogue among these capitals in recent years.
For such coordination to mature into a functioning security arrangement, several operational conditions must be met. Extended deterrence arrangements require clear consultation mechanisms. Pakistan’s nuclear status creates both opportunities and sensitivities. Confidential planning forums, analogous to historical NATO structures, could allow non-nuclear members to participate in threat assessment and scenario development without exercising direct control over weapons. Survivability of command, control and early-warning systems would need reinforcement through redundant links and hardened facilities spanning the group’s geographic depth.
Integrated air and missile defence represents another priority. The 2026 exchanges demonstrated the scale of missile and drone threats. Layered systems combining Saudi Patriot and S-400 equivalents, Turkish and Egyptian assets, and Pakistani technologies could improve coverage. Interoperability, however, demands standardised protocols, joint exercises and shared data links. Conventional force integration would benefit from common doctrine in areas such as counter-drone operations, maritime chokepoint defence and rapid deployment. Existing bilateral training relationships, particularly between Pakistan and Saudi Arabia or Türkiye and Pakistan, provide a starting point.
Defence-industrial cooperation offers a further avenue. Türkiye’s experience in unmanned systems and Saudi Arabia’s localisation targets under Vision 2030 could be aligned with Pakistani and Egyptian production capacities. Joint development or co-production programmes would reduce external dependencies and generate economies of scale. Intelligence fusion and cyber cooperation would complement these efforts. A permanent secretariat or working groups could coordinate threat assessments and exercise planning.
Extra-regional pressures will shape any such framework. The United States retains bases, arms supply relationships and diplomatic leverage. China offers economic partnerships and has played a background role in mediation. Russia maintains ties with several actors. Iran, though weakened, continues to pose asymmetric threats. Successful coordination would therefore need to manage relations with these powers rather than confront them directly. It would also need to accommodate differing national priorities. Türkiye maintains NATO membership and complex relations with both Russia and the West. Egypt balances ties with the United States and Russia. Pakistan focuses heavily on its eastern border. Saudi Arabia and Qatar pursue distinct hedging strategies.
Political obstacles remain substantial. Historical rivalries, ideological differences and competing regional ambitions have repeatedly complicated Arab and Islamic cooperation. Trust deficits are not easily overcome. Divergent threat perceptions persist. Some states view Iran as the primary challenge. Others worry more about Israeli actions or internal stability. Institutional capacity varies widely. Sustained political will across changing leaderships will be essential.
Technical barriers compound these difficulties. Equipment from diverse suppliers creates logistics and maintenance challenges. Classification and data-sharing restrictions limit intelligence cooperation. Command arrangements would require careful design to preserve national sovereignty while enabling collective action. Resource allocation poses further questions. Defence budgets face competing domestic demands, particularly in Pakistan and Egypt. Large-scale joint programmes would require multi-year financial commitments that governments may hesitate to make.
The risk of proliferation or escalation deserves careful attention. Any perception that Pakistani nuclear capabilities are being extended could provoke reactions from India, Israel or other actors. Clear declaratory policies and confidence-building measures would help manage these dangers. Equally, over-ambitious structures risk collapse if early tests reveal weaknesses. A phased approach therefore appears prudent.
Initial steps might focus on existing bilateral channels and the quadrilateral forum. Regular military staff talks, joint exercises in areas such as air defence and maritime security, and shared early-warning protocols could build habits of cooperation. Industrial offset agreements and technology transfers would deepen interdependence. Over time, these measures might evolve into more formal consultation mechanisms on extended deterrence and crisis management. A twelve-year horizon for meaningful operational capability seems realistic, assuming consistent political support.
The 2026 war demonstrated both the costs of strategic dependence and the limits of unilateral action. Middle powers now confront a choice between continued fragmentation and pragmatic coordination. The arithmetic of combined capabilities favours the latter. Political realities, however, constrain the pace and scope of integration. A loose yet credible consultative architecture, anchored in the quadrilateral process and the Saudi-Pakistani agreement, offers the most viable path forward. Whether the five states can translate recent diplomatic momentum into durable security arrangements will help determine the character of the Middle East order for decades to come. Success would mark a significant evolution in regional autonomy. Failure would leave individual states more exposed to coercion and spillover from great-power competition. The coming years will test whether shared vulnerability can overcome entrenched divisions.
