| 20 |  🔆 U.S.–Saudi Civil Nuclear Deal: Strategic & Non-Proliferation Concerns
📍 Why in Focus?
✅ The proposed U.S.–Saudi Arabia civil nuclear deal has sparked concerns over nuclear proliferation, Middle East geopolitics, and the future of the Abraham Accords.
📍 Key Highlights
✅ Saudi Arabia seeks nuclear energy to support Vision 2030, diversify its economy, and free more oil and gas for exports.
✅ The deal reportedly permits a peaceful nuclear programme but leaves ambiguity regarding uranium enrichment on Saudi soil.
✅ The U.S. later linked the deal to Saudi Arabia joining the Abraham Accords, creating uncertainty over the agreement.
✅ Critics argue the deal may weaken the global nuclear non-proliferation regime and further complicate regional tensions with Iran.
📍 Concerns
✅ No mandatory adoption of the IAEA Additional Protocol, limiting international safeguards and inspections.
✅ Enrichment capability could increase the risk of future nuclear weaponisation.
✅ Changing U.S. conditions have reduced Saudi confidence and may harden Iran’s negotiating position.
📍 UPSC Value Addition
✅ NPT: Recognises the right to peaceful nuclear energy while preventing nuclear weapons proliferation.
✅ IAEA Additional Protocol: Expands inspection powers and strengthens verification of peaceful nuclear activities.
✅ Abraham Accords (2020): Agreements normalising relations between Israel and several Arab states.
📍 Mains Question
“Civil nuclear cooperation must balance energy security with global non-proliferation objectives.” Examine in the context of the proposed U.S.–Saudi Arabia civil nuclear deal. (15 Marks, 250 Words)
