Signature, review, entry into force
The Department of Energy says the 123 agreement has been signed and will be transmitted to Congress. The sequence matters: signature shows that the two governments agreed a text, but it does not mean every political and legal threshold has been cleared before congressional review is complete. The Congressional Research Service framework for 123 agreements likewise distinguishes review from entry into force.[2], [3]
The following day Trump declared approval 'totally subject to' Riyadh normalising relations with Israel. White House press secretary Karoline Leavitt said the Saudi government had not been consulted before the post, and there was no public Saudi acceptance when the report was published. The condition is therefore a political position announced by the US president, not a jointly accepted clause of the agreement.[1]
The limit of the “no enrichment” line
The legal distinction in NPR's accessible syndicated report is narrower: the agreement and accompanying protocol do not expressly prohibit enrichment with US technology of fuel produced in a third country. That is not the same as an affirmative authorisation. The absence of a prohibition leaves open what future licences, implementing arrangements and safeguards would permit.[1]
The report also says the agreement lacks the UAE arrangement's 'gold-standard' enrichment ban and a requirement for the IAEA Additional Protocol. Those omissions are not evidence of misuse by themselves, but they make it necessary to ask which binding instrument and verification mechanism would implement Trump's public assurance that there will be no enrichment.[1], [2]
Four observable thresholds
The next institutional stage will take shape through four observable developments: which annexes accompany transmission to Congress, which conditions enter binding text during review, how Saudi Arabia responds to the normalisation demand, and what implementing documents say about enrichment and safeguards. Until those four developments become clear, it is not possible to say that normalisation will definitively make or break the agreement. For now, an institutional gap remains between the signed text and the political condition announced later.[2], [1], [3]
