President Donald Trump’s current enthusiasm for Saudi Arabia notwithstanding, the relationship between the United States and perhaps its most important ally in the Middle East is undergoing a significant transformation. U.S. political pressure on Saudi Arabia is rising, led by a growing congressional discomfort over the Saudi-led intervention in Yemen and the circumstances surrounding the murder of journalist Jamal Khashoggi, but that is just the tip of the iceberg.
Beneath the surface of the politics of the day, a pair of more significant geopolitical shifts is helping pull the longtime allies apart: the evolution of the global system away from U.S. dominance toward an intensifying, near-peer competition with China, as well as the fundamental reshaping of the global oil and gas markets upon which Saudi Arabia has built its wealth and power. As both countries adjust to these changing dynamics, their shared strategic relationship will evolve away from the foundation of oil, counterterrorism and the mutual desire to contain Iran. It’s likely that, as those changes play out, the countries’ future priorities will not align as they have in past decades.
A Relationship Built on Pragmatism
Despite their obvious differences, Saudi Arabia and the United States have maintained a nearly eight-decade friendship. From the beginning, the U.S.-Saudi relationship has rested on mutual needs, not necessarily shared values. A meeting in the waning weeks of World War II aboard the USS Quincy between U.S. President Franklin D. Roosevelt and King Abdulaziz (better known in the West as Ibn Saud) set the stage for their countries’ close ties. The stark contrast between the lands that they governed could not have been more apparent. Roosevelt, arguably the leader of the world’s most powerful and industrially advanced country, had just attended the Yalta Conference, where he helped decide the postwar future of the globe. King Abdulaziz, on the other hand, came from one of the least developed countries in the Middle East, its oil industry still in its infancy.

The fall of the shah of Iran in 1979 pushed their relationship in a different direction. This time, the United States and Sunni-dominated Saudi Arabia found themselves on the same side of the issue — with the Shiite-led Islamic Republic of Iran on the other. The Americans and the Saudis still were fighting communists, as their cooperation against the Soviet invasion of Afghanistan evidenced, although once the Soviet Union collapsed, so did the battle against communism as a unifying priority. Just a few years after the Cold War ended, however, another common foe emerged: Iraq’s Saddam Hussein. The Gulf War and subsequent U.S. dual containment policy targeting both Iraq and Iran in the 1990s brought the United States and Saudi Arabia closer together. But other events over the years have also pushed them apart. The Iran-Contra affair complicated the relationship in the 1980s, while the rise of the global jihadist movement emanating from the Wahhabism sect, which is closely identified with Saudi Arabia, added another wrinkle, particularly after 9/11.
