Saudi Arabia, Turkey and Pakistan sign mutual defense pact

Saudi Arabia, Turkey and Pakistan sign mutual defense pact

Rule Changes

Three states agree an attack on one is an attack on all, as Iran's war reaches the Gulf

Today: Turkey joins: the Mecca Joint Defence Agreement is signed

Overview

In Mecca, the leaders of Saudi Arabia, Turkey and Pakistan signed a pact stating that an armed attack on any one of them is an attack on all three. It binds oil-rich Saudi Arabia, Turkey's large army, and Pakistan's nuclear arsenal into one defense promise.

The signing lands mid-war. Since late February, Iran has fired missiles and drones at Gulf states, hitting Saudi oil refineries. For decades the Gulf leaned on the United States for protection. This pact builds a backup.

Why it matters

A mutual-defense promise now links Saudi oil, Turkey's army, and Pakistan's nuclear arsenal, changing who defends the Gulf if Iran strikes again.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

February 1955

Baghdad Pact / CENTO (1955)

Britain backed a defense pact linking Iraq, Turkey, Iran, Pakistan and later others against Soviet expansion. It aimed to build a Muslim-majority security bloc across the region.

Then

Iraq's 1958 coup pulled it out, gutting the pact's core.

Now

Renamed CENTO, it faded and formally dissolved in 1979 after Iran's revolution, never fighting as a bloc.

Why this matters now

It shows how regional defense pacts can look strong on paper yet unravel when members' politics shift. The Mecca pact faces the same test.

September 2001

NATO invokes Article 5 (2001)

After the September 11 attacks, NATO for the first time treated an assault on one member, the United States, as an attack on all 19 members.

Then

Allies contributed forces and surveillance to operations that followed.

Now

It proved a collective-defense clause can be activated, but also that invoking it is rare and heavy with consequence.

Why this matters now

The Mecca pact copies NATO's core promise. NATO's single invocation in decades hints at how high the bar to trigger one really is.

September 2025

Saudi-Pakistan bilateral pact (2025)

Saudi Arabia and Pakistan signed a mutual-defense agreement in Riyadh, days after an Israeli strike hit Hamas figures in Doha, Qatar. Its text did not mention nuclear weapons.

Then

It raised questions about a de facto Pakistani nuclear umbrella for Saudi Arabia.

Now

It set the template this year's trilateral pact expanded by adding Turkey.

Why this matters now

This is the direct precursor. The 2026 Mecca deal is its enlargement, so the same nuclear ambiguity carries straight over.
