Following the signing of the Mecca Joint Deterrence Agreement between Turkiye, Saudi Arabia, and Pakistan, Turkish Foreign Minister Hakan Fidan has expressed a desire to broaden the defense pact, potentially including other countries. The agreement, reminiscent of NATO, stipulates that an attack on any one of the three states would be treated as an attack on all. Egypt has been floated as a potential candidate for membership but may be cautious due to potential military obligations and implications for existing peace treaties. Analysts suggest that Egypt's inclusion could significantly increase the pact's political weight, regional influence, and operational effectiveness, provided it protects Egypt's aid relationship with the U.S., maintains its own freedom to decide when and where to fight, and does not undermine existing alliances or peace treaties. Other countries may also be considered for membership, which could further shape a new security architecture in the region and influence regional dynamics. The decision of each country regarding membership will depend on the strategic value it perceives in joining and its ability to manage relations with countries whose interests may contrast with or oppose those of the alliance.
