U.S. President Donald Trump said a new civil nuclear agreement with Saudi Arabia depends on the kingdom normalizing ties with Israel, a condition that could derail a landmark deal his administration finalized just a day earlier.

In a social media post Thursday, Trump also said there would be ¡°no enrichment¡± of nuclear material. The pact would allow American companies to expand nuclear energy development in a long-coveted market, but it also raised concerns about a lack of guardrails that would prevent Riyadh from enriching uranium to weapons-grade.

Trump said that the agreement ¡°will be approved, but is totally subject to Saudi Arabia joining the very respected and successful Abraham Accords,¡± referring to his initiative to get Arab countries to formally recognize Israel.
