Three military heavyweights formalize a trilateral security pact that could reshape the Middle East's strategic landscapeSaudi Arabia, Pakistan, and Turkey signed a trilateral joint defense agreement on August 7 in Mecca, bringing together three of the Muslim world’s most formidable military powers under a single security framework. The agreement builds on the Strategic Mutual Defence Agreement that Saudi Arabia and Pakistan signed on September 17, 2025, effectively upgrading a bilateral arrangement into something considerably more ambitious by folding in NATO’s second-largest military. Saudi Arabia commands the largest defense budget in the Gulf and serves as a dominant economic force across the region. Saudi Arabia continues to be one of America’s largest arms customers. The trilateral pact reinforces existing partnerships rather than replacing them, creating an additional layer of security coordination among nations that already cooperate bilaterally.
