Donald Trump just signed off on a 30-year civil nuclear cooperation agreement with Saudi Arabia. That single signature handed Riyadh a green light to pursue domestic uranium enrichment.
For decades, Washington held a firm line across the Middle East. If a country wanted U.S. atomic energy tech, it had to promise never to enrich uranium or reprocess spent fuel on its own soil. The United Arab Emirates accepted those terms back in 2009, creating what diplomats called the "gold standard" for non-proliferation.
This deal throws that playbook in the trash.
Riyadh gets U.S. nuclear technology, billions in commercial energy contracts go to American firms, and Saudi Arabia keeps its right to spin centrifuges at home. Critics on Capitol Hill are sounding alarms. Proliferation experts are warning about a new regional arms race. Yet the White House views this as a cold, pragmatic calculus to block China and Russia from taking over the Gulf's energy grid.
Here is what is actually inside this landmark deal, why it skipped standard security protocols, and what happens next as it hits Congress.
Inside the 123 Agreement
The legal foundation of this deal rests on Section 123 of the U.S. Atomic Energy Act. American law requires a formal 123 Agreement before U.S. companies can export significant nuclear material, reactor technology, or specialized equipment to another nation.
Without this agreement, firms like Westinghouse cannot bid on Saudi Arabia's ambitious commercial nuclear builds.
Under the terms negotiated between Washington and Riyadh, American vendors get primary access to build out Saudi Arabia's commercial reactors. In exchange, the U.S. gains commercial influence inside the kingdom's expanding energy infrastructure.
It sounds straightforward on paper. But the real spark comes from a joint U.S.-Saudi study built into the deal. That study lays out a direct path toward building a uranium enrichment plant inside Saudi Arabia.
Enriching uranium isn't inherently illegal. Power reactors need fuel enriched to roughly 3% to 5% Uranium-235. The problem is simple physics. The exact same centrifuge machinery that produces low-enriched civilian reactor fuel can keep spinning until it reaches 90% purity. That's weapons-grade material.
Once a country masters domestic enrichment, the line between peaceful power and nuclear capacity gets thin.
Bypassing the IAEA Additional Protocol
The most contentious part of this deal isn't just the enrichment clause. It's the inspection framework—or lack thereof.
Usually, Washington insists that foreign partners sign the International Atomic Energy Agency's (IAEA) Additional Protocol. The standard IAEA safeguards allow basic inspections of declared nuclear sites. The Additional Protocol goes much further. It gives international inspectors short-notice access to undeclared locations, broad authority to sample air and soil, and deep access to supply chain data.
This agreement does not require Saudi Arabia to adopt the Additional Protocol.
Instead, Washington and Riyadh agreed to a bilateral U.S.-Saudi verification framework. Administration officials argue this custom setup gives American auditors sufficient visibility over sensitive facilities. Arms control experts strongly disagree.
"Skipping the Additional Protocol creates a dangerous precedent. Without voluntary, unannounced IAEA access across undeclared sites, verifying that nuclear material hasn't been diverted becomes significantly harder."
When the UAE built its Barakah nuclear plant, it renounced domestic enrichment entirely and signed the Additional Protocol. That set a high bar for regional non-proliferation. By letting Riyadh bypass both safeguards, Washington made a permanent policy shift.
The Regional Security Powder Keg
To understand why Crown Prince Mohammed bin Salman fought for domestic enrichment, you have to look at the regional map.
Saudi Arabia sits directly across the Gulf from Iran. Tehran has spent years expanding its own enrichment network, running advanced centrifuges far past civilian purity levels. Crown Prince Mohammed bin Salman made his stance clear years ago: if Iran obtains a nuclear weapon, Saudi Arabia will follow suit as quickly as possible.
Riyadh wants nuclear parity. It doesn't want to rely solely on external security guarantees.
Recent military pacts underline that reality. Earlier this year, Saudi Arabia signed a mutual defense agreement with Pakistan, the only nuclear-armed nation in the Muslim world. Saudi officials openly stated the defense pact covers all military options.
By securing U.S. technology for fuel production, Riyadh secures the technical foundation of the full nuclear fuel cycle.
There is also a massive economic drive behind the move. Saudi Arabia holds native uranium ore reserves. Saudi Energy Minister Prince Abdulaziz bin Salman has repeatedly stated that Riyadh intends to mine its local ore, refine it into yellowcake, enrich it, and export commercial fuel. The kingdom wants to diversify away from crude oil while powering its own industrial expansion and massive water desalination plants.
Geopolitics and the China Threat
Why did the White House sign off on terms previous administrations rejected?
The answer comes down to global competition. Saudi Arabia made it clear to Washington that if American firms wouldn't build their reactors, state-owned companies from China or Russia would.
China National Nuclear Corporation (CNNC) has been bidding aggressively across the Middle East. Beijing doesn't attach human rights or non-proliferation demands to its commercial deals. Rosatom, Russia's state nuclear energy giant, already dominates reactor construction across the Global South.
Had Washington walked away, Riyadh likely would have signed a deal with Beijing.
That outcome would have anchored Chinese engineers, software, and military-adjacent technical staff inside Saudi critical infrastructure for 60 years. Administration strategists concluded that securing a U.S. footprint—even with softer non-proliferation terms—was better than yielding the entire Gulf region to Chinese influence.
The Congressional Battle Ahead
Now that President Trump has formally approved the deal, the clock starts ticking.
Under the Atomic Energy Act, the White House must submit the 123 Agreement to Congress. Lawmakers get a 90-day review period of continuous session to evaluate the text.
Stopping a 123 Agreement isn't easy. The deal automatically takes effect after the 90-day window unless Congress passes a joint resolution of disapproval. Even if both the House and Senate pass a resolution to block it, the President can veto it. Congress would then need a two-thirds supermajority in both chambers to override that veto.
Expect intense debate on Capitol Hill anyway.
Lawmakers from both parties have voiced alarm over regional proliferation. Opponents argue that giving Riyadh enrichment rights without the IAEA Additional Protocol undermines global pressure on Iran. Supporters argue that blocking the deal damages American manufacturing while handing Beijing a multi-billion-dollar win.
What Happens Next
This agreement marks a turning point in Middle Eastern geopolitics and global non-proliferation policy. Here are the immediate steps as this agreement moves forward:
- Formal Submission to Congress: The White House will transmit the final agreement text and classified national security evaluations to the House Foreign Affairs and Senate Foreign Relations committees.
- The 90-Day Congressional Review: Lawmakers will hold public hearings and classified briefings with State Department, Department of Energy, and intelligence officials. Expect intense questioning regarding the lack of the IAEA Additional Protocol.
- Joint Feasibility Study: Once the agreement takes legal effect, American and Saudi technical teams will launch the joint study assessing the site location, economic viability, and safety parameters for a domestic uranium enrichment plant in Saudi Arabia.
- Commercial Contract Bidding: Major U.S. nuclear energy vendors will begin finalizing contracts to supply technology, reactor designs, and operational expertise for Saudi Arabia's commercial nuclear power grid.
