Pakistan, Turkey, Saudi Arabia Strengthen Defense Alliance Amid Regional Shifts

Pakistan and Saudi Arabia signed a Strategic Mutual Defense Agreement in Riyadh on September 17, 2025, with Pakistani Prime Minister Shehbaz Sharif and Saudi Crown Prince Mohammed bin Salman declaring that any external aggression against one country would be treated as aggression against both. The pact formalizes decades of informal security cooperation between the two states, under which Pakistani forces have long provided training and, at times, garrison support inside the kingdom, and it gives explicit weight to Pakistan's status as the only nuclear-armed member of the Organisation of Islamic Cooperation.

The agreement came just over a week after Israel's September 9 airstrike on Doha, which targeted Hamas negotiators meeting to discuss a US-brokered ceasefire proposal and struck inside a Gulf state hosting the region's largest American military base. The strike jolted Gulf capitals into re-examining their reliance on US security guarantees, prompting Qatar's own push for firmer assurances and an emergency Arab-Islamic summit hosted in Doha on September 15 that both Pakistan and Turkey attended.

Turkey's defense relationship with Pakistan and Saudi Arabia has deepened along a separate but converging track. Ankara has supplied Bayraktar Akinci and TB2 armed drones to Riyadh since a 2022 deal, while Turkish shipyards have built MILGEM-class corvettes for the Pakistan Navy under a joint production program, alongside long-running army-to-army exercises between the two countries. Turkey also maintains a military base in Qatar, established in 2014 and expanded after the 2017 Gulf blockade, underscoring Ankara's role as a security partner across the Gulf-South Asia corridor now taking shape.

For Qatar, the tightening links between Islamabad, Ankara and Riyadh reinforce a broader regional trend: Gulf and Muslim-majority states pooling defense commitments in response to a security environment in which Israeli military action has, for the first time, reached Doha itself.
