(CNN) -- The world's most powerful democracy and the world's most absolute monarchy have long been close, if unlikely, allies.
They are bound together by common interests -- the free flow of oil and, more recently, fighting al Qaeda.
FDR and his advisors knew that oil, of which Saudi Arabia was well endowed, was a key component of America's economy. Indeed, Standard Oil of California had signed afarsighted deal a decade earlier giving it exclusive production rights in Saudi Arabia.
Thomas Lippman, who has written authoritatively on U.S.-Saudi relations, writes that as result of the meeting on the Quincy, the American president gave the Saudi king a DC-3 airplane that was specially outfitted with a rotating throne that allowed the king always to face the holy site of Mecca while he was in the air.
For his part, King Abdul Aziz so enjoyed his meals as the president's guest on board the Quincy that he surprised his host with an unusual demand: he wanted to take the Quincy's cook for himself. FDR was able to diplomatically ward off this request. (The concept that human beings are not personal property came to the Saudi kingdom relatively late; slavery was only abolished there in 1962.)
Elliott House on Saudi Arabia's outrage
When the Saudis really needed the States following Saddam Hussein's 1990 invasion of their neighbor Kuwait, the United States sent a half a million troops to the Gulf to expel Saddam's forces.
