The Saudi-Pakistani-Turkish Joint Defence Agreement, concluded on 7 August and referred to as the Mecca Joint Defence Agreement, marks a significant development in evolving strategic thinking in the Middle East.
The new alliance between the three Middle Eastern Sunni heavyweights draws a line across the troubled region and amplifies the sectarian divide with Shia Iran.
The agreement was signed in a ceremony held in Islam’s most holy city of Mecca by Saudi Crown Prince Mohamed bin Salman, Pakistani Prime Minister Shehbaz Sharif, and Turkish President Recep Tayyip Erdogan.
It establishes the principle that an armed attack on any one of the three countries would be treated as an attack on all three, reinforcing a collective defence commitment among the agreement’s members.
It builds on the Strategic Mutual Defence Agreement signed between Saudi Arabia and Pakistan in September 2025 and seeks to broaden defence and security cooperation among the three countries.
It also comes hard on the heels of the formation of a Saudi-led maritime force that Riyadh said is aimed at enhancing maritime security, protecting international maritime corridors, and countering threats targeting maritime navigation and global trade.
Saudi Arabia said 14 countries have affirmed their support for the Multinational Maritime Defence Coalition, including Turkey, Egypt, Pakistan, Nigeria, and several other Arab and African nations.
The coalition’s forces will be led by Saudi Rear Admiral Abdullah bin Salem Al-Shehri. Its detailed operational mechanisms, specific military commitments, and implementation provisions have not been publicly disclosed.
On the face of it, the tripartite bloc makes Turkey and Pakistan frontline states, while the naval force set up under the coalition will be tasked with protecting crucial routes for Saudi oil exports threatened by attacks by the Houthis in Yemen.
The new alliance, which has been touted as an “Islamic NATO”, will supposedly shift the balance of power against Iran, which has faced decades of multinational containment.
It will provide a framework for deeper military cooperation, including in areas such as joint exercises, defence-industrial collaboration, technology transfer, and intelligence sharing.
Turkey and Pakistan share over 1,400 km of land borders with Iran, and they will become the northern and eastern flank of the alliance, while Saudi Arabia will be on its southern border across the Arabian Gulf.
Saudi Arabia hopes other Sunni nations will join the alliance, and it has reportedly invited other countries including the United States and some European countries to join the new maritime coalition.
On paper, the new bloc and naval force will influence the management of regional security and will gradually erode most of the leverage Iran has enjoyed in its conflict with regional rivals.
Turkey and Pakistan combined possess greater strategic depth, greater military capabilities, a population of 400 million, four times that of Iran, and share military partnerships with the United States.
With Turkey maintaining roughly 355,000 to 481,000 active personnel and Pakistan fielding roughly 650,000 to 940,000 soldiers, the two nations rank ninth and 14th, respectively, out of the world’s 145 military powers.
While Pakistan ranks sixth or seventh globally in its total nuclear weapon inventory, holding an estimated 170 warheads, NATO member Turkey is a leading global power in drones that combine advanced artificial intelligence, precision munitions, and high-endurance flight capabilities for military operations.
The two countries outweigh Iran significantly in total firepower, and in theory they could shape a coordinated response with Saudi Arabia to Iran’s and its proxies’ threats and even advance their own version of a regional security structure.
As the current crisis in the region drags on, Pakistan has deployed some 8,000 troops, along with fighter jets, drones, and an air-defence system in Saudi Arabia, and it has opened negotiations with Kuwait to provide security in exchange for energy cooperation and investment.
Turkey, meanwhile, plays an active military role in the Middle East through mutual drills, cross-border operations, its military bases in Iraq, Somalia, Syria, and Qatar, and its defence exports.
However, while the three countries have sent a signal to Iran by signing the agreement with some pomp and circumstance, they have showed little desire to release details about the pact or explain its raison d’être to a sceptical public opinion in the region that is wary of further wars.
Historically, Saudi Arabia is bound by defence guarantees with the United States, and the two countries were close to sealing a bilateral defence treaty before the recent turmoil in the Middle East.
The deal was torpedoed by Washington’s insistence that the Saudis normalise relations with Israel first, even as it was pushing for American and Israeli commitments to Palestinian statehood.
More recently, Trump’s misbegotten Operation Epic Fury against Iran has empowered Tehran at the expense of its neighbours on the western side of the Gulf. It seems likely that once Trump has found a way out of the conflict, he will leave the Saudis and others to deal with the fallout.
However, with an American victory over Iran still out of reach, the situation has been further complicated by US concerns about the commitments made to Saudi Arabia and other Gulf allies.
General Dan Caine, chairman of the US Joint Chiefs of Staff, had reportedly warned Trump about the mismatch between the mission’s stated objectives and the resources at hand and had cautioned that the operation as a whole would be difficult without allied support.
Saudi Arabia cannot afford to abandon Washington, but its bid for closer integration among partners in the region may reflect a more apprehensive approach to its security needs and a way of facing up to US pressure.
With Trump beginning to “lower his profile” on the Iran issue, Tehran and its “Axis of Resistance” appear to be more resilient, making Saudi Arabia worried that the war could end without Iran’s defeat.
There are other reasons for Riyadh to rethink its traditional reliance on Washington for its security. Saudi Arabia wants to ensure its regional leadership through an assertive foreign policy that sets out clear security objectives against foreign threats.
As the Israeli wars on Gaza, Lebanon, and Iran and the US conflict with Iran have demonstrated, the Middle East security order continues to reel, and regional powers are struggling to fill the gap.
If implemented, the Saudi Arabia-Turkey-Pakistan defence pact will hold significant geopolitical importance and will likely trigger a reconfiguration of the regional order in the Middle East.
The most worrying aspect of such a reshaped structure would be its creation of a vehicle for deeper religious division in the region between Sunnis and Shias, as the alliance will likely stir up further sectarian polarisation across the Middle East.
Another problem is that talk of a military alliance bringing non-Arab Pakistan and Turkey together with Saudi Arabia has been met with unease by many Arab governments and has been greeted with widespread public disapproval.
Overlapping developments resulting from the fragmentation of traditional regional alignments are expected to spark geopolitical contestation by other powers and hence the weakening of institutional platforms for conflict resolution such as the Arab League and the Gulf Cooperation Council.
Evidence of reactions or inaction by regional actors demonstrates how the various players are simultaneously recalibrating their autonomy and reproducing new dependencies.
Key Arab countries such as Egypt, Iraq, and Oman, as well as North African players like Morocco and Algeria, are unlikely to cede regional leadership to Saudi Arabia and non-Arab countries.
Commentators reflecting the leadership’s thinking in the UAE, which has been alienated by Saudi Arabia and considers itself to be the “Gulf’s centre of gravity,” have already lashed out at the tripartite accord, with one key UAE voice describing it as lacking in credibility.
In Israel, which has formed a strategic economic and security alignment with India and the UAE, the media has described the emerging partnership as “mostly negative”, stressing that it is another sign of waning US influence in the region.
However, this is not the first time that Saudi policymakers have tried to reboot the region’s security to improve the country’s position and deter Iran, only to find that their attempts have been plagued by weak assumptions, exaggerated claims, and pointed ironies.
