The agreement and the assurance arrived together, and they contradict each other. Secretary of State Marco Rubio, on the signed US-Saudi nuclear deal: the United States 'is not going to reach any agreement with any country in the world that leads to the risk of proliferation' [3]. The deal itself, signed Wednesday by Energy Secretary Chris Wright and Saudi Energy Minister Abdulaziz bin Salman, drops the two provisions built to catch proliferation [1][2].

The first omission is the IAEA Additional Protocol - the enhanced-inspections standard that lets the agency search for undeclared nuclear activity rather than merely audit the sites a country declares [1]. The signed deal proceeds without it [1].

The second is the gold standard. When the United Arab Emirates signed its own 123 agreement, it accepted a binding bar on domestic enrichment and reprocessing - the model nonproliferation advocates call the gold standard [2]. The Saudi deal abandons it, opening a pathway to an enrichment facility after a joint US-Saudi study [2]. American firms would build the program without transferring sensitive technology, and the agreement now goes to Congress [2].

The context is not incidental to the claim. The deal was signed in the fifth month of a US bombing campaign whose stated aims include stopping enrichment in Iran, and Crown Prince Mohammed bin Salman has said openly that Saudi Arabia would pursue a nuclear weapon if Iran got one [2]. An enrichment pathway, minus the region's enrichment firewall and the agency's strongest inspections, is precisely the configuration those safeguards exist to prevent [1][2].

Rubio's sentence is a description of intent; the document is a description of terms [1][3]. When an agreement leaves out the two mechanisms designed to detect the risk an official says it carries none of, the terms are the record - and the terms say the tools are gone [1][2].
