Continuous relationship since 1945 — The Quincy meeting
On February 14, 1945, Roosevelt met King Abdulaziz Ibn Saud aboard USS Quincy in the Great Bitter Lake. No agreement was signed. Every king and every president since has reaffirmed what was understood there, which is the point: the foundation of the relationship is an understanding, and its terms have been argued about ever since.
The relationship is usually described as oil for security. That is roughly right and it was never a treaty. What is documented: the 1945 meeting; the 1973 embargo, which Saudi Arabia led against the United States; the 1974 Treasury arrangement under which the kingdom bought US debt outside the normal auction and its holdings were kept secret for forty-one years; the 1990 request that brought half a million American troops into the kingdom; fifteen of the nineteen September 11 hijackers; Congress overriding a presidential veto in 2016 so the kingdom could be sued; the 2018 murder of a US-resident journalist in a Saudi consulate; and, in November 2025, designation as a Major Non-NATO Ally. What is contested is the reading that turns the 1974 arrangement into a petrodollar system that props up the dollar. The card carries the documents and the dispute. The ruptures ran both ways and the relationship absorbed all of them.
This page covers structure, not sentiment. The 1974 arrangement is the most-cited fact about this relationship and the most-overstated; the card separates what the cables show from what has been built on them. Both sides of that dispute are sourced.
