The maneuvering in Congress unfolded as Secretary of State John Kerry met with Saudi Foreign Minister Adel Al-Jubeir, coming away without an immediate endorsement for the deal.

Saudi Arabia is committed to “resolutely” confronting Iran should it try to cause mischief in the region after signing the nuclear deal with world powers earlier this week, said Al-Jubeir.

The Saudi royal then contrasts this with the present situation with Iran, “where the strategic foreign policy analysis, the national intelligence information, and America’s allies in the region’s intelligence all predict not only the same outcome of the North Korean nuclear deal but worse – with the billions of dollars that Iran will have access to”.

She said the deal would cut Iran’s pathways to material for nuclear weapons and ensure the “vigorous” transparency and inspections needed to verify that Iran could not pursue a nuclear bomb. He will then travel to Saudi Arabia.

“Iran is a major player in the destabilization of the region”, Bandar wrote. “Saudi Arabia will not allow Iran to take advantage of this deal”.

At times, the King got involved, ordering an Iranian television station off the air or granting $1 million to an Islamic association in India.

Obama and al-Jubeir discussed “a range of regional and bilateral issues”, including the Iran agreement, Earnest said.

Concerns that Saudi Arabia has communicated privately to the United States have been enough to prompt US Defense Secretary Ashton Carter to announce a trip to Riyadh designed to allay the House of Saud’s fears and avert any military escalation.

Saudi suspicions of Iranian influence are nothing new, as diplomatic cables obtained by WikiLeaks show. The Saudi foreign minister added that his country was still in the process of reviewing the recently negotiated deal.
