The Mecca Agreement unites Pakistan, Saudi Arabia, and Türkiye in a joint defense pact. Reflecting shared strategic anxieties and West Asia’s evolving security, it pledges collective security and deterrence, treating an attack on one as an attack on all. This alliance, featuring nuclear Pakistan, influential Saudi Arabia, and drone-producing Türkiye, emerges as regional powers seek new partnerships beyond the U.S. security umbrella amidst ongoing regional wars. Its signing during active conflicts is a liability, potentially rendering collective defense symbolic. Credibility hinges on establishing a truly credible deterrent, currently absent.
