What if an attack on Islamabad or Riyadh tomorrow meant both armies—and even nuclear shadows—stood ready to respond?
What Exactly Is the Pakistan-Saudi Defense Pact and Why It Matters
The Pakistan-Saudi Arabia Mutual Defense Agreement, formally known as the Strategic Mutual Defense Agreement (SMDA), was inked on September 17, 2025, in Riyadh. It states that “any aggression against either country shall be treated as aggression against both.” Practically speaking, this means Pakistan and Saudi Arabia now have a NATO-like agreement to defend each other during war.
Pakistan has a military of 650,000 active personnel, 550,000 reservists, and 200,000 paramilitary troops, as well as an estimated 170–175 nuclear warheads. Saudi Arabia contributes 10.2 million barrels per day of oil—about 18% of global supply—and economic muscle already injected over $12 billion into Pakistan’s economy since 2018.
The signing came just after Israel’s September 9, 2025 strike on Doha, which killed Hamas leaders and rattled the Gulf, and months after the May 2025 India-Pakistan clash that killed 74 people in four days. Against this backdrop, Crown Prince Mohammed bin Salman declared at the signing: “Saudi Arabia will never stand alone again.” Pakistani Prime Minister Shehbaz Sharif called it “an alliance of faith, blood, and strength.”
How Pakistan and Saudi Arabia Built a Brotherhood Through Religion, Oil, and Military Cooperation
The pact rests on decades of brotherhood. Since 1947, Saudi Arabia has acted as Pakistan’s spiritual partner and financial lifeline, while Pakistan has defended the kingdom militarily. More than 2.7 million Pakistanis live and work in Saudi Arabia, sending home $6.6 billion in annual remittances—vital for Islamabad’s fragile economy.
Military cooperation began in the 1960s, when Pakistani troops were deployed to protect Mecca and Medina during regional instability. By the 1980s, this was institutionalized under the 1982 Bilateral Security Cooperation Agreement, which ensured permanent Pakistani deployments of 1,500–2,000 soldiers. In the 1990s, Pakistani pilots trained Saudi cadets, and since 2004, the “Al-Samsam” exercises have showcased joint readiness.
Economics has always reinforced the bond. After Pakistan’s 1998 nuclear tests, Riyadh provided billions in deferred oil, saving Islamabad from collapse. In 2018, Saudi Arabia pledged $6 billion in aid, while in 2022 it rolled over $3 billion in deposits during IMF talks. Beyond bailouts, Riyadh also invests in Pakistan’s mining sector, including interest in the $7 billion Reko Diq copper-gold project, and regularly buys Pakistani arms ranging from drones to small weapons.
Timeline of Saudi-Pakistani Brotherhood
| Year | Event | Impact |
| 1947 | Saudi Arabia recognizes Pakistan | Symbol of Islamic solidarity |
| 1960s | Pakistani troops protect holy sites | Start of military trust |
| 1982 | Bilateral Security Agreement | Institutionalized cooperation |
| 1998 | Aid after nuclear tests | Prevented economic collapse |
| 2018–22 | $9B bailouts | Stabilized Pakistan’s reserves |
What the Riyadh Pact Includes and How It Compares With Other Defense Treaties
The pact’s core is its mutual defense clause: an attack on one is an attack on both. It spans land, air, sea, and cyber defense. Though nuclear weapons are not named, Saudi Defense Minister Khalid bin Salman said it covers “all military means,” fueling speculation that Pakistan’s nuclear umbrella could extend to Riyadh.
Economically, it ties defense with development. Saudi Arabia pledged $5 billion for a Gwadar refinery, $1.2 billion annually in oil credits, and $1 billion for Pakistani arms procurement, including upgrades for 85 F-16 jets.
How It Compares Globally
- NATO’s Article 5: Automatic; invoked only once (after 9/11).
- U.S.-Japan Treaty: Asymmetric; U.S. protects Japan, but not vice versa.
- India-U.S. LEMOA/COMCASA: Focused on logistics and technology, not mutual defense.
- SMDA: Mutual, but requires consultation before activation.
In short, the pact is broader than India’s defense deals but weaker than NATO’s automatic clause.
Why the Defense Agreement Became Urgent After Wars, Oil Attacks, and Shifting Superpowers
The pact is a reaction to crises. Israel’s September 9, 2025 airstrike in Qatar killed 12 Hamas leaders and injured 40 civilians, highlighting Gulf vulnerability. Despite 45,000 U.S. troops in the region, Washington stayed passive—deepening Riyadh’s doubts.
The May 2025 Indo-Pak clash killed 74 soldiers and civilians and destroyed 18 military installations. Saudi mediation was vital, convincing Riyadh that formal defense ties would give it more leverage in South Asian crises.
Iran looms large. The IAEA confirmed in August 2025 that Tehran had enriched uranium to 60% purity, close to weapons grade. Meanwhile, Houthi rebels launched 27 missile and drone strikes on Saudi oil facilities this year, halting 3% of global shipping through the Red Sea.
For Riyadh, the pact hedges against U.S. unreliability. For Islamabad, it is economic survival: reserves had dropped below $4 billion in July 2025, inflation was at 22%, and debt repayments loomed. The pact means oil subsidies, cash deposits, and prestige as the “nuclear shield of the Muslim world.”
How the Pact Reshapes India’s Security Calculations, Gulf Politics, and Global Balance
India is directly affected. Saudi Arabia is India’s 4th-largest trading partner, with bilateral trade at $52.5 billion in FY24–25. Riyadh supplies 18% of India’s crude oil, and 2.6 million Indians live in the kingdom. Delhi now faces a strategic dilemma: Riyadh is both its biggest energy supplier and Pakistan’s new defense guarantor.
In Kashmir, Pakistan may feel emboldened. India’s surgical strikes in 2016 and 2019 may be riskier to repeat if Riyadh backs Islamabad. Nuclear ambiguity further complicates Delhi’s military planning. On September 18, 2025, India’s MEA spokesperson Randhir Jaiswal said: “We have taken note of the pact and will study its implications for India’s security and interests.”
The Gulf balance is shifting. The UAE, which signed a Comprehensive Strategic Partnership with India in 2022, may double down on Delhi to balance Riyadh’s tilt toward Islamabad. Iran dispatched envoys to Riyadh immediately after the signing, anxious about a Sunni bloc.
Globally, U.S. credibility suffers. Despite its regional footprint, Washington looks hesitant. China benefits: both Riyadh and Islamabad are Belt and Road partners, with $62 billion invested in CPEC. Energy markets are nervous. Analysts warn prices could spike to $120 per barrel, recalling the 2019 Abqaiq drone attack, which briefly removed 5.7 million barrels/day (5% of world supply).
Risks, Criticisms, and How the Pact Could Play Out in Real-World Scenarios
The pact faces limits. It is not automatic like NATO; activation requires consultation. The two countries are separated by 2,000 km, making rapid troop deployment difficult. Pakistan’s military is largely India-focused, so major commitments to Saudi Arabia could weaken its eastern defense.
Critics fear nuclear ambiguity undermines the Non-Proliferation Treaty. Saudi Arabia denies seeking nukes, but Crown Prince MBS’s 2024 remark about “buying a bomb from Pakistan” still echoes.
Possible Scenarios
- A renewed Kashmir crisis where Pakistan invokes Saudi backing.
- A Houthi missile strike on Aramco that sees Pakistani troops defending oilfields.
- The pact remains symbolic, deterring aggression without activation.
Public and Media Reaction
- In Pakistan, hashtags like #IslamicNATO trended on X within hours.
- Saudi state media hailed the pact as part of Vision 2030’s security pillar.
- In India, editorials called it “symbolic posturing,” but warned of terror safe havens.
- Israeli think tanks called it “a setback for normalization with Riyadh.”
- Western experts from the Stimson Center and Belfer Center called it “a watershed moment,” but stressed its logistical limits.
A Brotherhood Written in Law but Still to Be Tested by Reality
The Pakistan-Saudi Arabia Mutual Defense Pact is the culmination of 75 years of brotherhood built on faith, money, and military trust. For Pakistan, it brings prestige, modernization, and much-needed cash. For Saudi Arabia, it delivers manpower, credibility, and potential nuclear cover. For India, it creates strategic uncertainty. For the world, it underlines America’s waning dominance and China’s rising influence in the Gulf.
But the pact’s true meaning lies ahead. Will it remain a symbolic shield, deterring aggression without ever being used? Or will it one day become a sword, drawn in crises from Kashmir to the Red Sea? Either way, from September 17, 2025 onward, no one can discuss Gulf or South Asian security without mentioning the Pakistan-Saudi defense pact.
