‘Attack on one is attack on all’: Saudi Arabia, Turkiye and Pakistan sign landmark Mecca defence pact

Saudi Arabia, Turkiye and Pakistan have signed a landmark joint defence pact declaring that an armed attack on any one of the three countries will be regarded as an attack on all. The pact is seen as a major development that could reshape regional security amid Israel’s expansionist wars and growing uncertainty over the reliability of the US security umbrella.

The “Mecca Joint Defence Agreement”, signed today, is intended to strengthen collective deterrence and security cooperation between three of the Muslim world’s most militarily and strategically significant states.

“The agreement is intended to strengthen collective deterrence against any act of aggression” and stipulates that an armed attack against any of the three countries “would be regarded as an attack on all”, according to a joint statement cited by Reuters.

The pact brings together NATO member Turkiye, which has the alliance’s second-largest military, nuclear-armed Pakistan and Saudi Arabia, one of the Gulf’s most powerful states and the world’s leading oil exporters.

A Turkish official described the agreement as “purely defensive in nature”, saying it pledged mutual support for defence and was not aimed at any particular country. The official added that the arrangement was open to other regional states and would not replace existing bilateral or multilateral commitments.

However, despite the striking “attack on one, attack on all” language, important questions remain over how far the pact goes in practice.

Middle East analyst H A Hellyer, a senior associate fellow at the Royal United Services Institute (RUSI), urged caution over interpreting the announcement as the creation of a fully fledged NATO-style military alliance.

Responding to the agreement on X, Hellyer questioned how much could be inferred from the headline declaration before the precise commitments undertaken by the three governments become clear.

“One should be very wary about considering that this would actually take immediate effect, irrespective of the signing of it” said Hellyer. “If Saudi were attacked by Iran tomorrow (entirely plausible), I doubt Riyadh would truly expect Ankara and Islamabad to treat it as an attack on them”.

The joint statement does not specify what military assistance each country would actually be required to provide if another member came under attack. Early reports provided no details about the “commitments or obligations” accepted by the three governments.

No integrated command structure, automatic troop deployment mechanism or NATO-style military decision-making body has so far been announced publicly.

Nevertheless, the political symbolism is considered to be major step.

Abdulaziz Sager, chairman of the Gulf Research Center, described the gathering as a demonstration that three of the Muslim world’s most influential states are increasingly willing to coordinate their security policies.

“If institutionalised and translated into concrete cooperation,” Sager said, the framework could increase their combined diplomatic and military weight and contribute to a more regionally driven security architecture.

The agreement comes amid an extraordinary deterioration in regional security.

In response to the US and Israel’s war on Iran, the Islamic Republic launched attacks against Saudi Arabia and other Gulf states, while disruption in the Strait of Hormuz has threatened a route which carried around one-fifth of global energy supplies before the conflict.

Saudi Arabia has faced attacks from Iran as well as the Houthis in Yemen and armed groups in Iraq. A senior Saudi official warned on Thursday that Riyadh expected possible coordinated attacks from Iraqi militias to the north and the Houthis to the south.

But the new pact is not being shaped by concern about Iran alone.

Reuters reported that Saudi Arabia, Turkiye and Pakistan are also concerned about Israel’s increasingly aggressive regional military posture.

Since October 2023, Israel has carried out its devastating assault on Gaza, invaded southern Lebanon, seized further Syrian territory and launched major attacks against Iran.

The pact also reflects a broader debate among regional powers about reducing dependence on the US for their security.

Saudi Arabia in particular has faced increasingly difficult questions about the reliability of Washington’s security guarantees as repeated conflicts have threatened the kingdom’s territory, oil exports and ambitious economic transformation plans.

Former Qatari Prime Minister Sheikh Hamad bin Jassim Al Thani called earlier this year for Egypt, Saudi Arabia, Turkiye and Pakistan to establish a strategic defence alliance, describing such a grouping as an “urgent need” amid changing regional and international conditions.

Egypt has not joined the Mecca pact, although it has increasingly coordinated with the three signatories. Foreign ministers from Turkiye, Egypt, Pakistan and Saudi Arabia have held a series of consultations through the four-country R4 grouping, most recently meeting in Cairo in June.

Whether Cairo or other regional states eventually join the new defence framework remains unclear.
