Saudi Arabia has sought a formal U.S. security commitment as part of a larger diplomatic package that could include relations with Israel. Publicly discussed U.S.-Saudi terms have included a defense agreement, arms cooperation, and civil nuclear cooperation, but proposals and press reporting are not a signed treaty. The Congressional Research Service (CRS) summarizes the possible arrangements and the questions Congress may face in its report on possible U.S.-Saudi agreements.
Treaty or executive agreement?
If the administration submits a treaty, the Constitution requires the advice and consent of two-thirds of Senators present. That threshold does not automatically apply to every security arrangement: the final legal instrument could instead be an executive agreement or legislation. The instrument selected determines the route through Congress and the scope of any U.S. commitment.
A defense promise also has to be read in its actual text. A commitment to consult or respond under constitutional processes is not identical to an automatic obligation to enter a war. CRS outlined possible models and noted that the exact terms would shape congressional scrutiny. No public final U.S.-Saudi defense treaty text establishes the obligations in a normalization package.
Arms sales and Israel’s military edge
Major arms transfers follow separate statutory review and notification rules. U.S. law requires the executive branch to assess whether proposed arms sales to Middle Eastern countries would adversely affect Israel’s qualitative military edge, or QME. QME is a legal and policy assessment of Israel’s ability to counter credible military threats; it is not a blanket ban on sales to Arab states. Congress can review sales, seek changes, or attempt to block them through legislation.
For each transfer, the type of weapon, recipient, quantity, and proposed safeguards matter. A general promise to preserve QME does not settle which systems would be sold or how their effect would be evaluated. The CRS report describes both the possible defense commitments and the arms-sale questions linked to normalization.
Nuclear cooperation has its own review
Significant U.S. civil nuclear cooperation requires a Section 123 agreement under the Atomic Energy Act. The President submits the agreement and required documents to Congress for a review period generally totaling 90 days of continuous session, subject to statutory counting rules and exceptions. Congress can enact a joint resolution disapproving the agreement; if it does not, the agreement can take effect under the statute.
Section 123 agreements must meet nonproliferation criteria and provide U.S. consent rights over specified uses and transfers of U.S.-origin nuclear material and technology. The law does not require every partner to renounce domestic enrichment. Whether a Saudi agreement contains a UAE-style renunciation is a negotiated question. Read the nuclear page for those safeguards.
The U.S. bargain therefore has several congressional choke points rather than one universal vote. The governing provisions appear in Section 123 of the Atomic Energy Act: treaty consent if treaty form is used, arms-sale review, statutory nuclear review, and any legislation needed to implement commitments. The package overview explains how these American components were linked to the Saudi-Israeli track.
