In my analysis for the Center for Strategic and International Studies (CSIS), Next Generation Nuclear Network (NGNN), titled A Critical Juncture for Saudi Arabia’s Nuclear Ambitions and U.S. Policy Under Trump, I explore how Riyadh’s pursuit of indigenous nuclear capability intersects with the evolving contours of non‑proliferation and U.S. foreign policy.

Saudi Arabia asserts its sovereign entitlement under the Treaty on the Non‑Proliferation of Nuclear Weapons, seeking parity with other enrichment‑capable states. Yet this aspiration collides with Washington’s insistence on the renunciation of enrichment and reprocessing technologies, a condition long embedded in U.S. nuclear‑cooperation agreements. The prospective return of President Donald J. Trump—whose foreign‑policy posture has historically favoured transactional diplomacy and recalibrated alliances—may reshape the negotiating landscape. Early commentary suggests that a second Trump administration could revisit prior constraints, though official policy positions would need to be confirmed through authoritative sources.

The analysis contends that Riyadh’s nuclear trajectory is inseparable from the broader regional security environment. Iran’s advancing nuclear capabilities, coupled with persistent anxieties over Middle Eastern instability, imbue Saudi ambitions with an existential hue. Should Washington maintain stringent restrictions, the Kingdom may seek alternative patrons—South Korea or, more disquietingly, China—whose cooperation could inaugurate a more precarious era of proliferation and strategic fragmentation.

Ultimately, the Saudi nuclear question emerges as a fulcrum of regional equilibrium. Whether tethered to American security guarantees or liberated through more flexible partnerships, the Kingdom’s choices will bear profound consequences for the credibility of the global non‑proliferation regime, the balance of power in the Middle East, and the future architecture of nuclear governance.
