The United States and Saudi Arabia announced a landmark civilian nuclear cooperation agreement on Wednesday, an accord the Trump administration has described as historic, even as it draws sharp criticism from lawmakers and nonproliferation advocates given its timing amid the ongoing U.S.-Israeli war against Iran, a conflict rooted substantially in concerns over Tehran’s own nuclear ambitions.
What Was Signed
The agreement was formalised through two separate documents: a “peaceful nuclear cooperation” agreement, commonly referred to as a 123 agreement under Section 123 of the U.S. Atomic Energy Act of 1954, and an accompanying bilateral safeguards agreement. Both documents were signed by U.S. Energy Secretary Chris Wright and Saudi Minister of Energy Prince Abdulaziz bin Salman.
According to the U.S. Department of Energy, the two agreements together lay the legal foundation for what is expected to be a decades-long, multi-billion-dollar partnership between the two countries, one intended to advance a combination of economic, strategic, and nonproliferation-related objectives. Energy Secretary Wright described the agreements as reflecting the shared commitment of both nations to strengthening bilateral commercial relations, while insisting that the deal upholds the highest standards of nuclear safety and nonproliferation, relying specifically on American-developed nuclear technology and expertise.
What the Deal Will Involve
Under the agreement, American companies will provide nuclear technology to Saudi Arabia to help establish a civilian nuclear power programme within the kingdom, intended to support energy generation for purposes such as AI data centres rather than military applications. Westinghouse Electric Company, a major American nuclear reactor manufacturer, is among the U.S. firms expected to play a role in developing Saudi Arabia’s nuclear sector under the new arrangement.
According to U.S. officials, the deal is structured to last 30 years and could ultimately open the door to uranium enrichment taking place on Saudi soil, though any such enrichment activity would reportedly be controlled by a contracted corporation and would only proceed following the completion of a lengthy study process. The full text of the agreement had not been publicly released at the time of the announcement.
Why This Deal Is Controversial
The prospect of uranium enrichment capability being extended to Saudi Arabia has long been a point of significant concern among nonproliferation experts and U.S. lawmakers from both parties, given that uranium enrichment and plutonium reprocessing represent the two primary technical pathways through which countries can produce the core materials necessary to build nuclear weapons. Most countries operating civilian nuclear reactors that require enriched uranium do not produce this material domestically, instead purchasing it from established vendors such as the United States or Russia under strict international supervision, an arrangement the new U.S.-Saudi deal appears to depart from in its potential allowance for domestic enrichment capability.
Adding to these concerns, Saudi Crown Prince Mohammed bin Salman has previously pledged that the kingdom would pursue its own nuclear weapon should regional rival Iran ever succeed in producing one, a statement that has fuelled longstanding unease among those wary of a deal that could provide Saudi Arabia with enrichment infrastructure. U.S. Senator Bernie Sanders was among the deal’s most vocal critics, arguing that the Trump administration’s stated rationale for its war against Iran, namely preventing an authoritarian government from enriching nuclear fuel, appeared inconsistent with extending similar enrichment-adjacent capability to Saudi Arabia, a government he characterised in starkly critical terms.
The Government’s Response to Proliferation Concerns
Addressing these concerns directly ahead of the announcement, U.S. Secretary of State Marco Rubio stated that the United States would not enter into any agreement with any country that carried a risk of nuclear proliferation. Energy Secretary Wright similarly emphasised that the agreements were designed specifically to uphold rigorous nonproliferation standards while relying on American-developed nuclear technology and scientific expertise throughout the programme’s implementation.
Congressional Review Ahead
Under the terms of the 1954 Atomic Energy Act, all nuclear cooperation agreements between the United States and foreign governments must undergo formal review by Congress before taking full effect. The newly signed U.S.-Saudi deal will now be submitted for this congressional review process, though observers have noted that the currently Republican-controlled legislature is considered unlikely to block the agreement’s implementation despite the concerns raised by critics from both parties.
A Deal Years in the Making
Wednesday’s formal signing builds on groundwork laid considerably earlier. The two countries had signed a preliminary Joint Declaration on the Completion of Negotiations on Civil Nuclear Cooperation back in November 2025, during a visit by Saudi Crown Prince Mohammed bin Salman to the United States that also produced a range of other bilateral agreements, including a significant expansion of Saudi investment commitments in the U.S., reportedly reaching close to $1 trillion. That same visit also saw the two countries sign a Strategic Framework for Cooperation on Securing Uranium, Metals, Permanent Magnets, and Critical Minerals Supply Chains, reflecting a broader pattern of deepening economic and strategic engagement between Washington and Riyadh well beyond the nuclear sphere alone.
The pursuit of a civilian nuclear agreement with Saudi Arabia itself stretches back even further, with American officials having explored the possibility of such a deal as far back as the Obama administration, reflecting the kingdom’s longstanding interest in developing domestic nuclear capacity alongside persistent American caution regarding the proliferation risks such cooperation could entail.
Regional Context: The Ongoing Iran Conflict
The timing of the deal’s announcement carries particular significance given the ongoing U.S.-Israeli war against Iran, which began in late February and has centred substantially on concerns over Tehran’s nuclear programme, one Iran has consistently maintained is intended solely for civilian purposes. Saudi Arabia has itself long asserted its own right to pursue a civilian nuclear programme, mirroring similar arguments made by Iran regarding sovereign energy development, even as the geopolitical rivalry between the two regional powers continues to shape the broader security dynamics of the Middle East. Notably, Saudi Arabia signed a mutual defence pact with nuclear-armed Pakistan the previous year, a development that has further shaped perceptions of the kingdom’s broader strategic posture regarding nuclear-related security matters.
Why This Matters
Beyond its immediate commercial and energy implications, the U.S.-Saudi nuclear deal is likely to be viewed as a significant marker of the deepening strategic partnership between Washington and Riyadh, one that intersects directly with some of the most sensitive and closely watched nonproliferation debates currently shaping Middle East geopolitics. Given Israel’s status as the only country in the region believed to possess a nuclear arsenal, and the ongoing conflict with Iran over its own nuclear ambitions, any expansion of nuclear-related capability elsewhere in the region is likely to draw sustained international attention and scrutiny in the months ahead.
What Happens Next
With the agreement now signed and set to proceed through congressional review, attention will turn to how Congress engages with the deal’s specific provisions, particularly those relating to potential uranium enrichment capability, during the review process. Given the significant scale of the partnership envisioned, spanning decades and multiple billions of dollars in investment, further details regarding the programme’s implementation, safeguards, and oversight mechanisms are expected to emerge as both governments move toward the deal’s practical execution.
