A new joint defence agreement between Pakistan, Saudi Arabia, and Türkiye signals a significant shift in the Gulf’s security landscape. While not intended to replace the United States’ role, the pact reflects growing concerns among Gulf states about the limitations of relying solely on American security guarantees. Recent events, including attacks on energy facilities and disruptions to shipping, alongside perceived wavering US commitment, have fueled the need for supplemental security measures. The Makkah Joint Defence Agreement aims to foster cooperation through mutual defence planning, intelligence sharing, and joint military training. This defensive pact prioritizes institutionalized collaboration between nations with existing strong relationships, avoiding the creation of a formal military bloc or integrated command structure. Each nation will maintain sovereign control over its own decisions. Therefore, the agreement represents an attempt to bolster regional stability independently while complementing existing security arrangements.
