Pakistan, Saudi Arabia, and Turkey have signed a collective defence agreement in Mecca that treats an attack on one member as an attack on all.

The pact represents a significant shift in regional security architecture as these nations seek a collective mechanism to navigate instability. The move comes as the U.S. deepens its conflict with Iran, prompting regional states to reconsider their reliance on traditional security guarantees.

Led by Prime Minister Shehbaz Sharif, Crown Prince Mohammed bin Salman, and President Recep Tayyip Erdogan, the three [1] nations formalized the alliance through the Mecca Joint Defence Agreement. The treaty establishes a mutual defence framework designed to mirror the structure of the North Atlantic Treaty Organization.

"Any armed attack against any one of the three states shall be regarded as an attack against them all," the joint statement of Pakistan, Saudi Arabia, and Turkey said.

The agreement aims to provide a stable security buffer for the signatories. By formalizing this bloc, the three countries create a consolidated military front that operates independently of Western-led security umbrellas.

Analysts suggest the agreement may create strategic openings for other global powers. Specifically, the shift toward a localized defence bloc could provide China with a greater foothold in the Middle East as regional priorities diverge from U.S. foreign policy goals.

The treaty was signed in Mecca, Saudi Arabia, marking a rare alignment of these three regional powers into a single binding military commitment.

An attack on any one of the three will be considered an attack on all.

The formation of the Mecca Joint Defence Agreement signals a move toward strategic autonomy for Saudi Arabia, Turkey, and Pakistan. By establishing a mutual defence pact, these nations are hedging against the volatility of U.S.-Iran relations and reducing their dependence on Washington. This vacuum in U.S. influence may allow China to expand its diplomatic and security footprint in the Middle East, potentially shifting the global balance of power in the region.
