US lawmakers are awaiting the text of the Trump administration's nuclear cooperation agreement (NCA) with Riyadh, which was announced last week shortly before US President Donald Trump upended the deal's future by conditioning it on Saudi normalization with Israel. Commercial interests in Washington remain optimistic that the White House will submit the deal to Congress, starting the clock on a 90-day Congressional review. But blocking the deal and overriding a presidential veto would require a two-thirds majority. Ratification could help shore up the languishing US nuclear sector, which today has more prospective technologies than contracts.
