Saudi Arabia, Turkey, and Pakistan have signed a mutual-defense pact that reshapes power in the Middle East — bad news for Israel, the UAE, and India, and a sign that US influence in the region is fading.

• Signed in Mecca on August 7, the deal treats an attack on one country as an attack on all, like NATO's core promise.
• It links the Muslim world's only nuclear power, its only NATO member, and its largest economy into one bloc — though Pakistan's nuclear umbrella is left deliberately vague.
• Despite headlines, the pact is not really about Iran, which is now an isolated outsider; it's aimed at a wider rivalry against Israel, the UAE, India, and their partners.
• Pakistan has already put 8,000 troops, jets, and air defenses on Saudi soil, while staying out of direct strikes so it can broker Iran-US talks.
• Egypt, Qatar, Kuwait, and others are seen as likely future members, turning this into the backbone of a lasting regional coalition.

Outlook: Expect the three nations to secure the Persian Gulf and Red Sea against Iran and the Houthis near-term, while a longer cold war with the Israel-UAE-India camp plays out over decades.
