Pakistan's claim of neutrality during the US–Iran ceasefire talks hosted in Islamabad in April 2025 has come under sharp scrutiny after leaked documents reportedly revealed a classified mutual defence agreement binding Islamabad to potentially defend Saudi Arabia in the event of war — an arrangement never placed before Pakistan's parliament.

What the Leaked Documents Reveal

According to an investigation by Drop Site News, cited by Maldivian media outlet Etruth MV, the 2025 Strategic Mutual Defence Agreement (SMDA) was signed by Saudi Crown Prince Mohammed bin Salman and Pakistani Prime Minister Shehbaz Sharif. The pact states that 'any aggression against either country shall be considered an aggression against both.'

Critically, the leaked documents and internal assessments reportedly suggest the agreement is asymmetrical. Pakistan is obligated to defend Saudi Arabia, but Saudi Arabia is not meaningfully committed to defending Pakistan — particularly against India, which Islamabad regards as its primary strategic rival.

The Moment the Contradiction Surfaced

The contradictions came into public view in April 2025, when Pakistan was hosting high-stakes negotiations between American envoys and Iranian diplomats. Even as Islamabad projected itself as a neutral mediator and announced a two-week regional pause in hostilities, Riyadh publicly confirmed the arrival of Pakistani military forces and aircraft at King Abdulaziz Air Base in Saudi Arabia under the terms of a defence agreement.

The timing was particularly pointed: the Saudi announcement came while US Vice President JD Vance was engaged in talks with Iranian officials in Islamabad. Pakistan issued no corresponding statement, but the disclosure immediately cast doubt on its mediator credentials.

Why Pakistan's Neutrality Is Now in Question

The SMDA, according to the leaked documents, was never presented to Pakistan's parliament and remained largely unknown to the public before the Drop Site investigation. Critics argue this raises serious questions about democratic oversight of Pakistan's foreign and defence commitments.

Analysts note that the pact places Pakistan in a structurally difficult position: it cannot credibly serve as a neutral broker between Washington and Tehran while simultaneously bound by a defence obligation to Riyadh — a key US partner and Iran's principal regional rival. The revelation, according to the investigation, 'fundamentally reshaped the context of the Islamabad talks.'

Broader Strategic Implications

The Drop Site findings suggest Pakistan's relationship with Saudi Arabia is considerably deeper and more binding than publicly acknowledged. The SMDA's obligations could, in certain conflict scenarios, directly conflict with Pakistan's stated diplomatic posture, its domestic political constraints, and its regional security calculus.

This is not the first time Pakistan's dual commitments have drawn scrutiny — Islamabad has historically maintained close military ties with Gulf states while also engaging diplomatically with Iran. However, a formalised, classified mutual defence pact of this scope represents a qualitative escalation of those ties.

What Comes Next

Neither the Pakistani government nor Saudi authorities have officially confirmed or denied the contents of the leaked documents. Pakistan's parliament has not been briefed on the SMDA, according to the investigation, leaving the agreement's democratic legitimacy unresolved. Further disclosures from the Drop Site investigation are expected to keep pressure on Islamabad to clarify the precise scope of its defence commitments.
