Israelis are warning that the new U.S.-Saudi nuclear agreement could trigger a regional arms race, with critics saying the deal gives Riyadh access to sensitive nuclear technology without the strictest nonproliferation safeguards. Former officials and opposition leaders in Israel argue that allowing uranium enrichment on Saudi soil could push other powers, including Iran, Turkey, and Egypt, to seek similar capabilities.
Why Israel is alarmed
The immediate concern in Israel is not just the civilian nature of the agreement, but the possibility that civilian nuclear infrastructure could eventually be converted into weapons capability. Reuters reported that the deal would allow Saudi Arabia to build nuclear reactors with American technology and enrich uranium, a combination that critics say could undermine the region’s fragile balance of power.
Former Israeli Prime Minister Naftali Bennett called the agreement a “serious strategic failure,” warning that nuclear enrichment on Saudi territory could lead to “a regional nuclear race and a dangerous loss of control.” Former defense minister Avigdor Lieberman was even blunter, saying the Saudi program “will end in nuclear weapons” and spark a “crazy arms race throughout the entire Middle East.”
Those warnings reflect a long-standing Israeli fear that once one regional rival is allowed to master parts of the fuel cycle, others will insist on the same rights. In a region already defined by distrust and recurring conflict, that kind of precedent is viewed in Jerusalem as strategically dangerous even if the Saudi program remains officially civilian.
The regional domino effect
The fear in Israel is not limited to Saudi Arabia itself. Analysts and Israeli commentators say a deal granting Riyadh enrichment rights could encourage Iran, Turkey, and Egypt to push for equivalent capabilities, turning civilian nuclear programs into symbols of regional status and strategic insurance.
That domino effect is what makes the agreement so politically explosive in Israel. Israel is widely believed to possess the Middle East’s only nuclear arsenal, even though it does not publicly acknowledge it, and many Israeli officials see any new enrichment program in the region as a threat to that ambiguous deterrent balance.
Former Israeli nuclear and defense officials have argued for years that Riyadh’s demand for enrichment could “open Pandora’s box,” setting a precedent that other governments would use to justify more advanced fuel-cycle capabilities. Once that door opens, opponents say, it becomes much harder for Washington to tell other allies they cannot have the same thing.
Why the U.S. deal matters
The deal is especially sensitive because it is being negotiated over Israel’s head, according to Reuters and Israeli reports. That has given critics in Israel a second grievance: not only do they fear the technical risks, but they also feel shut out of a decision that could reshape the strategic environment around them.
Reuters noted that Prime Minister Benjamin Netanyahu and his defense and foreign ministers had not publicly commented on the agreement as of Thursday, even as opposition figures rushed to condemn it. Israeli security sources quoted by i24NEWS said officials privately fear the agreement could accelerate a broader regional race for nuclear capabilities.
The omission of the strictest nonproliferation safeguards is at the heart of the dispute. Critics say the deal could permit enrichment without the kind of airtight monitoring that would limit the risk of weaponization, while supporters argue the civilian energy benefits and U.S. oversight would make the arrangement manageable.
Israel’s political reaction
The deal has quickly become a domestic political issue in Israel, where opponents of Prime Minister Netanyahu are using it to argue that his government has lost strategic leverage with Washington. Bennett and other opposition figures have framed the agreement as evidence that the U.S. is willing to move ahead without securing Israeli preferences, particularly on a matter that touches on national security.
Some Israeli commentators see a wider diplomatic message in the timing. They argue that if the Trump administration is prepared to finalize a nuclear deal with Saudi Arabia despite Israeli objections, then Washington may also be signaling a new willingness to act independently on the Iran war and other regional security issues.
That possibility has unnerved Israeli officials already grappling with the widening fallout from the Iran conflict, which has made nuclear issues even more politically charged. In this climate, the Saudi deal is being read not just as an energy arrangement, but as a test of how far U.S.-Israel alignment can stretch.
Proliferation and precedent
Arms-control advocates have long argued that civilian nuclear programs in the Middle East can create a “latent” weapons capability if enrichment and reprocessing are permitted. That concern is now front and center again because the Saudi deal appears to relax the barriers that normally separate peaceful nuclear energy from weapons potential.
The U.S. has historically insisted on strict conditions in such agreements to keep partners from using imported technology as a springboard to a bomb. But Reuters reported earlier this year that the Trump administration was already removing some of those guardrails from the proposed Saudi pact, a move that alarmed nonproliferation experts before the current Israeli backlash emerged.
What makes the Saudi case different, critics say, is the regional context. Unlike in other parts of the world, the Middle East already has active nuclear tensions, unresolved conflicts and states that watch one another closely for signs of strategic imbalance. That makes any loosening of restrictions far more likely to be interpreted as a green light for others.
What happens next
The next major test will be the U.S. congressional review process. Israel’s critics of the deal are likely to intensify lobbying efforts on Capitol Hill in hopes of tightening safeguards or blocking the agreement entirely.
If Congress accepts the deal as drafted, Israeli officials will likely be left to manage the fallout rather than shape the outcome. That could deepen the sense in Jerusalem that Washington is increasingly prepared to make major regional decisions even when they clash with Israel’s core security concerns.
For now, the broader fear is simple: once Saudi Arabia is allowed to enrich uranium, the logic of nuclear restraint in the Middle East may become much harder to enforce. That is why critics in Israel are treating the deal not as a standalone agreement, but as the possible start of a much wider and more dangerous regional competition.
