Why did three massive Muslim powers just sign a secret defence pact?

Saudi Arabia, Turkey, and Pakistan have formalised a joint defence agreement signed in Mecca, establishing a powerful new security bloc. The pact brings together Turkey's advanced domestic military industry, Saudi Arabia's immense financial clout, and Pakistan's nuclear capabilities. This alliance emerges during severe regional instability, as conflicts involving Iran, Israel, and the United States threaten global trade routes and oil supplies. While Riyadh seeks reliable regional security guarantees after perceived Western failures, Turkey aims to expand its defense exports, and cash-strapped Pakistan gains critical financial backing. For India, this development demands close diplomatic navigation. The strategic convergence of Pakistan with key West Asian powers could alter regional security dynamics, even as New Delhi maintains strong bilateral and trade ties with both Riyadh and Ankara.
