Senate Democrats Introduce Resolution to Block US-Saudi Nuclear Deal Citing Proliferation Risks

BLUFDemocratic opposition to the US-Saudi 123 agreement is unlikely to reach a Senate floor vote by year-end, letting the deal take effect by default and pressuring the UAE to seek matching enrichment terms.

Sens. Jeff Merkley and Ed Markey introduced a joint resolution of disapproval on Thursday to block the Trump administration's civil nuclear cooperation ("123") agreement with Saudi Arabia, according to Merkley's office 1 and The Hill 2. The senators say the deal lacks the "gold standard" bar on enrichment and reprocessing and does not require the Additional Protocol for IAEA inspections 1. The agreement takes effect after a 90-day review unless Congress passes the resolution, and the Senate vote can come after November 29 1. Jewish Insider reported most Republicans support the deal, though some have voiced concerns, and House Democrats introduced a similar resolution 3. Common Dreams noted the measure would need veto-proof majorities in both chambers 4.

Analysis
The Senate is unlikely to hold a floor vote on the Merkley-Markey resolution by December 31, 2026. Confidence is high because the sponsor's release and The Hill agree on timing and Jewish Insider's account of Republican support fits them, though most claims trace to the sponsor's release. The 90-day review clock, not the resolution, decides the outcome, so the agreement takes effect by default unless Republican holdouts break ranks. Passage would need veto-proof majorities in two GOP-controlled chambers, and a November 29 earliest vote date leaves little floor time before recess. The introduction may instead be a messaging vehicle to put Republicans on record ahead of the midterms. If no vote occurs, Riyadh and Abu Dhabi can proceed on enrichment terms, and the UAE's right to renegotiate its own 123 terms becomes the next pressure point.
