Why in News :On September 17, 2025, Saudi Crown Prince Mohammed bin Salman and Pakistani PM Shahbaz Sharif signed the Strategic Mutual Defence Agreement (SMDA) in Riyadh.

Background of Saudi–Pakistan Defence Ties
- Origins (1951): Defence links formalised soon after Pakistan’s creation.
- Golden Period (1979–89): ~20,000 Pakistani troops stationed in Saudi Arabia to protect holy sites and counter Iran/Yemen.
- Post-1990 Decline: Pakistan withdrew troops; later refused deployments during 1990 Kuwait crisis and 2015 Yemen war.
- Perceptions: Saudis treated Pakistanis as “paid guards,” while Pakistani officers resented subordination. Sectarian (Shia exclusion) issues further strained ties.
- U.S. Factor: Pentagon traditionally shaped this alliance. Recent Trump–Munir meeting suggests U.S. nudging behind SMDA.
Saudi Calculations
1. Declining U.S. security umbrella: Israeli strike on Qatar (2025) exposed U.S. reluctance to defend GCC allies.
2. Avoidance of Arab/Turkish troops: To prevent domestic political contagion.
3. Nuclear hedge: Pakistan’s nuclear status could deter Iran if it goes nuclear.
4. Weapons buildup: Riyadh already ordered ~$100 bn U.S. arms; SMDA supplements deterrence.
Pakistan’s Calculations
- Economic Lifeline: Oil supplies and Saudi funds to rescue its fragile economy.
- Military Hardware & Training: Access to advanced Saudi equipment.
- Strategic Leverage vs India: Use Saudi insecurity to extract geopolitical concessions.
- Limited Commitment: No intention to fight Iran, Yemen, or Israel directly; mainly transactional gains.
Key Challenges
- Historical mistrust between Saudi monarchy and Pakistani military.
- Divergent threat perceptions: Riyadh vs Tehran, Islamabad vs New Delhi/Kabul.
- Pakistan’s China & Iran ties complicate alignment with Saudi–U.S. bloc.
- Nuclear sensitivities: Technology transfer unlikely due to Israeli red lines, though A.Q. Khan precedent fuels suspicion.
- Domestic & sectarian politics: Shia exclusion, clerical opposition to foreign troops.
- Credibility gap: Pakistan’s past refusals (1990, 2015) show it avoids costly interventions.
- Optics vs reality: More symbolic “insurance policy” than substantive defence guarantee.
Implications for India
1. Energy Security: As world’s 3rd largest oil importer, India must safeguard supplies amidst shifting Saudi alignments.
2. Diaspora Factor: Over 2 million Indians in Saudi Arabia depend on stable bilateral ties.
3. Strategic Balance: Riyadh explicitly stated its intent to balance Pakistan with India, “also a nuclear power.”
4. Economic Partnership: Saudi plans $100 bn investment in India; strong trade (India = 2nd largest Saudi partner).
5. Defence Cooperation: India–Saudi defence/intelligence ties since 2014 offer a counterweight to SMDA.
6. Diplomatic Leverage: Riyadh reportedly kept New Delhi informed during SMDA talks — shows India’s weight in Saudi calculus.
7. Cautionary Note: SMDA could give Rawalpindi indirect confidence, though India’s economic heft tempers Saudi tilt.
Conclusion
The SMDA reflects Saudi Arabia’s insecurity and Pakistan’s opportunism rather than a genuine long-term alliance. For Riyadh, it is a hedge amid declining U.S. reliability and Iran’s rise. For Islamabad, it is a financial and strategic rent-seeking opportunity.
