Defence Minister Khawaja Asif, sitting before a camera of a Pakistani Television Channel, said on Monday night one thing which was unimaginable even five years ago. He raised the prospect of Turkey and Qatar formally joining the Strategic Mutual Defence Agreement (SMDA) – the key pact signed by Pakistan with Saudi Arabia in September 2025 – and said it was a "welcome development". He didn't call it a military build-up, he called it a regional peace architecture, a structure that lessens external reliance and creates stability from within the neighbourhood.

It's a deliberate framing. In many ways, it's also deceivingly modest.

What's being formed, quietly, at diplomatic conferences in Doha, Riyadh, Ankara and Islamabad, is the body of a new security bloc, made up of four of the most significant Muslim countries: Pakistan, Saudi Arabia, Turkey and Qatar. These four countries have a total population of more than 500 million. The Turkish Armed Forces are the sixth largest in the world. Saudi Arabia's economy is now a trillion dollar economy. The estimated number of warheads in the possession of Pakistan is 160–170. For Qatar has one of the most strategically located territories in the world: Al Udeid Air Base is the single largest American airbase in the Middle East as well as a Turkish military installation. These aren't small players hedging quietly. These are big ones with purposeful movement.

How We Got Here

Saudi Crown Prince Mohammed Bin Salman and Pakistani Prime Minister Shehbaz Sharif signed the SMDA in Al-Yamamah Palace on September 17, 2025. It was no accident. Israeli air attacks on Doha on September 9, 2025, “flandered the Gulf states' sense of security”, and “strengthened their doubts over America's commitment to protecting their partners”, the Financial Times reported.

It was an anxiety that had been building up for years. Saudi Arabia and Pakistan signed a defense deal in part because of U.S. failure to act on two occasions: the Iranian drone strikes on Saudi oil facilities in 2019 drew only mild U.S. condemnation; and Israeli strikes on Qatar in 2025 were met with a lukewarm U.S. rebuke.

The pact's core clause pledges both countries to consider any aggression against one an aggression against both, a clause for collective security that is clearly inspired by Article 5 of NATO treaties. As Dawn newspaper in Karachi put it, “the most significant upgrade to Pakistan–Saudi defence relations in decades.”

The nuclear issue was always a cloud over the announcement. The Defence Minister of Pakistan has earlier indicated in that regard a nuclear sharing aspect but later reiterated that there is no such scope. The deal "encompasses all military means," a Saudi official told Reuters without explicitly confirming coverage of nuclear. This vagueness was most likely intentional. Riyadh and Islamabad are seeking a level of certainty of risk they don't want to cement in irreversible measures such as forward-basing warheads in Saudi Arabia.

What every country has to offer

The principle of a possible bloc is complementarity. Every state has their own unique niche that the other ones can't do on their own.

Pakistan adds a capability to operate nuclear weapons. Turkey contributes a large conventional army and a large industrial base. Saudi Arabia has tremendous financial power, diplomatic influence and religious credibility as guardian of the holiest places of Islam. Qatar also enjoys a unique and irreplaceable geographic and diplomatic location: it is home to the United States' most important regional airbase, a Turkish military presence, and maintains close and cordial ties with nearly all regional players, even Hamas, Iran, and the Taliban.

According to Turkish security sources quoted by Al-Jazeera, Ankara's main reasons for considering joining such an alliance would be Pakistan's nuclear capability and Saudi Arabia's economic and political clout, with Turkey's participation expected to be through its high-tech military industries and the world's sixth-largest military.

Saudi Arabia has announced its intentions to localize more of its defense expenditures under Vision 2030 which will demand technology-sharing partners. Pakistan also has a history of co-production with China in defense technologies and can, as was the case during the India-Pakistan crisis in May 2025, be used as an operational testbed for advanced Chinese weapons.

A lot of economics is at stake here. Saudi Arabia's bilateral deals with Pakistan already valued at $2.8 billion, inked in October 2024. As cooperation in defence advanced between the two nations, Saudi Arabia was able to purchase JF-17 Thunder fighters from Pakistan, defense analysts commented at the time. Over the decades, the Pakistan army has trained thousands of Saudi military personnel—some estimates suggest the number of Saudi personnel trained is around 8,000-10,000 and Pakistani military personnel have been deployed in the kingdom at various times since the 1960s.

The defense deal is also a reflection of Saudi Arabia's Vision 2030 planning program, which focuses on self-reliance in the Saudi defense sector, including growing Saudi military capacity and a domestic arms industry, as Riyadh has come to realize that it is not enough to build a strong economy to maintain influence.

The economic aspect is equally important as the strategic aspect for Pakistan. In 2023, Pakistan's military chief had pledged to bring in $75–100 billion worth of investments from Saudi Arabia, the UAE, Qatar and Kuwait. In April 2026, Saudi Arabia and Qatar provided Pakistan with a $5 billion loan, while Pakistan started sending fighter jets to Saudi Arabia, the first concrete step under the defense pact.

From the ruins of an ancient city, a tide of energy that changed history.

But knowing why this bloc is coming together now means knowing what changes have occurred in Washington's stance. Gulf states are trying to work out their security in ways they have not had to before in the Trump era.

The Saudis are very sensitive to the whimsical shiftiness of US policy towards the Middle East. They can't count on that going forward, if they haven't already faced the type of coercion President Donald Trump is all too willing to apply to other close partners.

Islamabad's involvement in Trump's Board of Peace in Gaza had been an indication of its readiness to expand its involvement beyond its immediate vicinity. The US have themselves described Pakistan as an “incredible” mediator in the nuclear talks with Iran, which were held here.

But this is actually the "burden sharing" that Washington wants. Essentially, the US is asking Saudi Arabia to become the main player on the Palestinian issue, as a leading Arab power. This led Saudi Arabia to understand that it was not possible — and perhaps did not want — to do it alone, and that it required partners like Turkey. Riyadh was concerned about the increasing influence of Turkey and brought in Pakistan as a counterweight to Turkey and Iran.

The nuance of this inner balance, where Saudi Arabia would like to have Pakistan on its side as well as keeping Iran at bay, is what most discussion on this topic overlooks.

Discomfort in India, Counter-Move in Israel

No nation is more disturbed by these developments than India. The deal could change India's security calculations, said Ian Bremmer, a geopolitical analyst, if Saudi Arabia is keen on defending Pakistan in case of such a war. Speakers with The Hindu said that the timing seemed to be a warning after the May 2025 military confrontation between India and Pakistan.

Turkey even went so far as to block the transit of Indian military equipment in the midst of the short India-Pakistan confrontation, openly favouring Islamabad. Structural alliance, not just opportunistic, after a Turkey formally ensconced in a Pakistan-Saudi pact.

Israel doesn't look away and neither is it silent. Israeli Prime Minister Benjamin Netanyahu has proposed an alternate regional alliance bloc — the “Hexagon of Alliances” — that he sees as Israel's security and economic alliance with India, Greece, Cyprus and some Arab, African and Asian countries. Meanwhile, the US could be left with no option but to review its regional partnerships and form a more even military alliance between the UAE, Bahrain, Kuwait, Cyprus and Greece, with Israel signing a trilateral plan for military cooperation with Greece and Cyprus in 2026.

The development of two rival regional architectures are happening side by side. One is based in Riyadh, Islamabad, Ankara and Doha. The other in Tel Aviv, Abu Dhabi, Athens and possibly New Delhi. It is the "Middle Ground" that will determine the next 10 years in the Middle East.

The Skeptics Have a Point

There is a grain of caution here, though, as the difference between declaration and practise in the Middle East is often enormous.

The limitations faced by this quadrilateral are fundamental ones, such as different threat assessments, absence of institutionalisation, economic weakness, and internal political instability in some member countries. The same conditions – lack of institutionalization and divergent national interests – have caused previous regional initiatives, such as the Baghdad Pact of the '50s, to come to failure.

Indeed, the Saudi financial inflows would be welcomed in aiding Turkey's economy, which is struggling with inflation, as they have been in Pakistan. However, it is unrealistic to expect any offer by Pakistan to extend nuclear deterrence to Turkey. Pakistani missiles are not able to fully target Turkey's potential enemies.

What would Saudi Arabia do if Pakistan and India fought another war on the border, risk its developing economic ties with India, a key trading partner? For Vision 2030, the ambitious economic transformation goals, the Crown Prince has been working to put in effect a "no problems with neighbors" policy in the Saudi foreign policy.

Some Turkish commentators read the anonymous briefing on their country's involvement as more of an attitude rather than a genuine intention towards Islamabad – more of a message to Washington.

These are good questions. However, they talk about the boundaries of a bloc that is still in formation, not evidence that it will not form. Many analysts saw the September 2025 SMDA as symbolic. The treaty's operational implications were then tested for the first time in April 2026 when Pakistan sent fighter jets to Saudi Arabia. It was a faster turnaround of the symbolism to substance than was anticipated.

The Bigger Picture

The moves are not just a response to the growing regional uncertainty. They also form an integral part of a broader campaign to alter the regional order and maintain Saudi Arabia's dominant role — at the UAE's cost no less, which, along with Israel, is viewed in Riyadh not just as an economic rival but as a nation actively involved in undermining Saudi interests, most notably in the Red Sea region.

Pakistan Army Chief has an image of a ‘resilient fortress of the Muslim world' implying that Pakistan should be strong first for the good of the Muslim world. The geopolitical dimension of this vision going regional is the SMDA's potential expansion to Turkey and Qatar.

Gulf's time of relying on single-point security is now over. The era of layered, local deterrence has started.

The nature of the four-nation arrangement remains up for debate as to whether it will ever come to resemble a joint defense pact, with shared command structures, joint procurement processes and binding mutual obligations, or whether it will remain a "fluid consultation and coordination mechanism rather than a formal alliance," as one Moscow-based think-tank put it.

The previous attempt of a group of Muslim-majority countries to establish a NATO-like security organization was destroyed by the Cold War. Today's circumstances are quite different: The United States is not the committed superpower it was in 1955; the region's other key players have more stable institutions than they did in the past; and the provocation is both pressing and constant: Israeli military action, U.S. erraticism, Iranian pressure.

Pakistan's defence minister might have described the possibility of Turkey and Qatar's involvement as "welcome. But Washington, New Delhi, Tel Aviv and Abu Dhabi have different takes on it. They're likely right to, are they?
