Yes, you really did get that backwards.
Here's a picture of the Shah having a chat with Kennedy in the White House.
And Nixon was so incensed by that "non-dollar oil sales" that Nixon went to visit the Shah after he was deposed.
During his second exile, Mohammad Reza Pahlavi traveled from country to country seeking what he hoped would be temporary residence. First he flew to Assuan, Egypt, where he received a warm and gracious welcome from President Anwar El-Sadat. He later lived in Morocco as a guest of King Hassan II, as well as in the Bahamas, and in Cuernavaca, Mexico, near Mexico City, as a guest of José López Portillo. Richard Nixon, the former president, visited the Shah in summer 1979 in Mexico.
And then when the Shah got sick, the USAF flew him to the US for medical treatment.
The Shah suffered from gallstones that would require prompt surgery. He was offered treatment in Switzerland, but insisted on treatment in the United States.
On 22 October 1979, President Jimmy Carter reluctantly allowed the Shah into the United States to undergo surgical treatment at the New York–Weill Cornell Medical Hospital. While in Cornell Medical Center, Mohammad Reza Shah Pahlavi used the name "David D. Newsom" as his temporary code name, without Newsom's knowledge.
The Shah was taken later by U.S. Air Force jet to Kelly Air Force Base in Texas and from there to Wilford Hall Medical Center at Lackland Air Force Base. It was anticipated that his stay in the United States would be short; however, surgical complications ensued, which required six weeks of confinement in the hospital before he recovered. His prolonged stay in the United States was extremely unpopular with the revolutionary movement in Iran, which still resented the United States' overthrow of Prime Minister Mosaddegh and the years of support for the Shah's rule. The Iranian government demanded his return to Iran, but he stayed in the hospital
So...we disappointed our good friends who deposed the hated Shah by treating him and then protecting him in the US, or you got it backwards.
Btw, written on the US/english Wikipedia page about "that Shah" is
The Shah's diplomatic foundation was the United States' guarantee that they would protect him, which was what enabled him to stand up to larger enemies.
There are three instances of the word "dollar" on that page, and none of them have to do with oil sales.
Also, Nixon wasn't president in 1963. Kennedy was until November, then LBJ was. So how, exactly, did the Shah "bluntly refuse toward Nixon" in 1963 when Nixon was not at all part of the government? All Nixon was in 1963 was ex-Vice President who lost to Kennedy.
