Congress Already Wrote the Rule This Deal Breaks

A Feasibility Study, Not a Constraint

On 22 July 2026 the United States and Saudi Arabia signed what Time called "a watershed civilian nuclear cooperation agreement," one that "could pave the way for uranium enrichment in the kingdom."⁴ The administration's own announcement of the signing is brief and says little about how. The mechanics come from reporting on the deal's terms, not from that statement. According to the New Republic, the agreement sets up a two-year joint US-Saudi study of "the economic feasibility of domestic enrichment in Saudi Arabia."⁵ If that study finds enrichment is not economically justified, the same reporting says, Saudi Arabia would be barred from pursuing it for ten years. If it finds enrichment feasible instead, the United States would build the facility itself, restricting "Saudi Arabian citizens access to the sensitive technology."⁵ Either branch keeps an independently Saudi-built enrichment program off the table for now. Neither branch keeps enrichment off the table.

Nor does the agreement carry the Additional Protocol. Al Jazeera reported before the signing that it was "not expected to include" the IAEA's expanded inspection regime.⁶ CNN's account of the signed text drops the hedge: the kingdom "is notably not required to sign" the Additional Protocol with the IAEA, unlike the UAE, which did in 2009.⁷ What replaces it is a bilateral US-Saudi safeguards arrangement that, the Arms Control Association reports, reaches only "locations at which sensitive United States-Saudi civil nuclear cooperation would occur."⁸ Any enrichment activity built, financed, or supplied outside that footprint sits outside the arrangement by design, not by oversight.

The Standard the UAE Met and Saudi Arabia Didn't

Washington has answered this question before, with a different answer. The UAE's 2009 123 agreement renounced enrichment and reprocessing outright and committed the country to ratify the Additional Protocol, terms nonproliferation officials still call the "gold standard."⁹ Section 123 of the Atomic Energy Act already gives the United States a tool to hold a partner to that line on its own: one of its nine statutory criteria reserves Washington's prior consent over any enrichment or reprocessing activity a partner undertakes.¹⁰ Congress tightened that tool in July 2019, when the House adopted the Sherman amendment setting the no-enrichment, Additional Protocol standard as a condition of any Saudi deal reaching a vote.¹

A second lock followed a year later. The 2020 National Defense Authorization Act ordinarily bars the executive branch from even submitting the nuclear proliferation assessment a 123 agreement needs for congressional review, when the partner has not accepted enhanced safeguards. The Trump administration waived that bar to submit this agreement anyway.¹¹ Outside analysts read the incentive the waiver creates the same way. Foundation for Defense of Democracies analyst Andrea Stricker warns the exception could open "a Pandora's box of Russia and China providing these technologies to others simply because the United States did it first."¹² Congress built the standard and then waived its own gate to get around it.

Capability Turns Intent Into a Timeline

Crown Prince Mohammed bin Salman has already said what an enrichment capability would be for. CBS News' Norah O'Donnell asked him directly, in a "60 Minutes" interview broadcast 18 March 2018, whether Saudi Arabia would seek a nuclear weapon. His answer: "Saudi Arabia does not want to acquire any nuclear bomb, but without a doubt if Iran developed a nuclear bomb, we will follow suit as soon as possible."¹³

That condition sits closer to met than it has in years. The IAEA assessed in March 2026 that Iran holds just over 200 kilograms of uranium enriched to 60%, enough for roughly five weapons once enriched further to weapons grade, and its inspectors went nearly a year without being able to verify Iran's declared stockpiles at all.¹⁴

An enrichment plant does not hand a state a bomb. It hands the state the part of the timeline that used to take years to build: the equipment, the trained staff, and the technical base to move from low-enriched fuel toward weapons grade without starting from zero. What stands between that capability and a weapon is verification, and verification is exactly what this deal declines. The IAEA's Model Additional Protocol gives inspectors "complementary access" to any location on as little as 24 hours' notice, "at least two hours" where the visit accompanies a design review or an inspection already under way at that site, and less than two hours "in exceptional circumstances."¹⁵ The bilateral arrangement in the Saudi deal reaches only the facility the two governments jointly fund.⁸ A government watching its rival build enrichment capacity does not measure the difference by how reassuring the paperwork sounds. It measures how many days would pass before anyone outside the building could tell something had changed.

The Case for Signing Anyway

The strongest case for this deal does not deny the risk above. It says the risk is smaller than the alternative. Jennifer Gordon, writing for the Atlantic Council, makes the industry argument and the nonproliferation argument at once: a 123 agreement with Saudi Arabia "is not only a win for the US nuclear energy industry," she writes. "It is also a victory for the US-led global nonproliferation regime," because "US involvement prevents Saudi Arabia from turning to Russia or China for nuclear technology."¹⁶ Time reports the administration making the market half of that case in its own words too: the deal gives "great access for American companies in the Saudi nuclear energy program, benefiting American industry, workers, and supply chains."⁴ On this reading, a Saudi civil-nuclear program is coming whatever Washington decides. The live question is only which supplier builds it, and every rival supplier with the technology to offer answers to fewer inspectors than the one asking for restraint. The same expert reaction Gordon's piece gathers suggests something further: the UAE's no-enrichment standard already looks less like a fixed rule and more like a first offer other Gulf states may not accept twice. A constrained Saudi enrichment option could also give Washington something to trade against Iran's own stockpile in whatever negotiation comes next. No official record examined here states that trade outright, but it sits inside the same strategic logic.

Grant all of it. American supervision beats none. Moscow and Beijing would impose fewer conditions. A standard already under strain from other suitors cannot be defended forever by holding still, and a Saudi enrichment option gives Washington something to spend in a future Iran negotiation. None of that answers the question that decides whether this deal is safe. That question is how many days pass between a decision to build a weapon and a bomb. Nothing in Gordon's case, or the department's, shortens that number. It only changes who is in the room while the clock runs.

Gordon's own premise even undercuts itself. The reason American involvement is supposed to beat the alternative is supervision: a US partner watches what Riyadh builds. But the bilateral safeguards arrangement this deal actually writes covers only the facility the two governments jointly fund and operate.⁸ Anything enriched, stored, or built outside that footprint sits outside the inspection regime she credits with keeping the country safe, including work done with the workforce and technical base this very deal trains up. The supervision she describes does not reach the capability the deal creates.

The reversal this argument would need is not hypothetical. The UAE accepted the Additional Protocol and a no-enrichment pledge in 2009.⁹ Saudi Arabia has accepted neither. Three things would have to hold. Riyadh signs and implements that protocol. The enrichment facility the joint feasibility study may yet produce operates under the Model Additional Protocol's complementary-access inspections rather than the narrower bilateral arrangement now on the table. The ten-year bar reported for the case against enrichment becomes a permanent one, not a contingency the same study could clear. Meet all three and this paper's judgment reverses. Absent that, the deal buys an ally's goodwill and an industry's market against a clock nobody has agreed to stop.
