The Saudi-American Nuclear Deal Could Reshape Nonproliferation For Decades

For nearly two decades, the United States and Saudi Arabia negotiated on and off over a civilian nuclear cooperation agreement. That effort reached a milestone in late July 2026, when the U.S. Department of Energy announced it had formally signed a nuclear deal with the Kingdom of Saudi Arabia. This, for the first time, opens a pathway for Saudi Arabia to enrich its nuclear fuel. The Trump administration has framed the agreement as a historic energy and strategic win. But strip away the rhetoric and what's left is a set of choices with consequences that could outlast this administration by decades: a possible arms race in the Middle East, a weakened global nonproliferation regime and a template other nuclear-aspiring nations will now point to when they come asking for the same terms as Iran.

From Declaration to Signed Agreement

The roots of the deal stretch back through both the first Trump administration and the Biden administration, each of which held talks with the Saudi government over nuclear cooperation, often tied to broader discussions about Saudi normalization with Israel. The framework accelerated in November 2025, when President Trump hosted Crown Prince Mohammed bin Salman at the white house. During that visit, the two countries signed a joint declaration on civil nuclear energy, alongside a major defense package that included the sale of F-35 fighters, which was the first sale to Saudi Arabia. That declaration described the arrangement as building “the legal foundation for a decades-long multi-billion-dollar nuclear energy partnership” and pledged that cooperation would proceed under strong nonproliferation standards. Energy Secretary Chris Wright called it a historic moment. Nine months after that declaration became a signed agreement. Wright and the Saudi energy minister put pen to paper on a deal that commits Saudi Arabia to using American companies for reactors and fuel supply. The agreement is reportedly set to be in effect for 30 years and to transfer American nuclear technology to the Kingdom of Saudi Arabia. 

What sets the deal apart and what triggered the most criticism is the ability for Saudi officials to enrich uranium on their own soil. Under most US nuclear cooperation agreements, known as “123 agreements” of the Atomic Energy Act, partner countries agree to forgo enrichment and reprocessing entirely, relying on imported fuel. That standard has been a type of security check of US nonproliferation policy for decades. This was specifically because if one is enriching it for civilian energy use, it can be used the same to make weapons-grade uranium. Saudi officials have long resisted signing onto the no enrichment standard, arguing that a genuine energy program requires domestic enrichment on home soil. Saudi Arabia has also been notably reluctant to accept a lot of international safeguards, such as allowing inspectors to fully verify that their nuclear programs are only for civilian use. The resistance to that raises a lot of questions when they are now being given access to nuclear energy as if they truly intend to use it only for civilian use fully. The immediate fear, of course, is the Iranian nuclear threat. Saudi Prince Mohammed bin Salman has said publicly that if Iran acquires a nuclear weapon, Saudi Arabia will attempt to as well. With Iran's own program being under immense pressure from the US and Israel, handing the Saudis enrichment abilities under a civilian label risks being read across the world as the US only supporting non-proliferation when it comes against their own interests. The more important part of this to think about is the precedent it will set. Once Washington grants one partner an enrichment agreement, the logic now for others will be “why not us as well” becomes very hard to argue against. Every future 123 negotiation with South Korea, Turkey, or others who have shown interest in enrichment in the past will now have the precedent of why the Saudis but not us. This could set the end of non-proliferation and all the work that has been done in the last 50 years to lower the nuclear threat to the world. 

The 90-day Window 

Under US law, Congress now has 90 days to review the agreement and either block it or pass it. The lawmakers are expected to push for tighter enrichment limits and debate the bill in general. Unwinding an agreement like this would require a joint resolution of disapproval, which just makes Congress a pressure valve, not a veto.  The imbalance in the deal is what is worrying critics, as this is a huge precedent to set, and if it is passed, there is not much going back, with the consequences multiplying very quickly. Specifically, the Iran-Saudi rivalry and the nuclear proliferation that could follow. It complicates the US diplomatic standing as well when the next country is asked to follow enrichment restrictions when the Saudis were not held to that. The Israel normalization condition Trump has added after signing makes it possible the deal falls apart entirely as well. Either way, a precedent already has been set with Washington showing it's willing to offer enrichment rights to a partner that has openly said they will pursue one. That signal is very hard to take back regardless of how this agreement shapes out.
