The Shaw and his security apparatus did.
Everyone else still remembered Operation Ajax.
The
Shah.
The vast majority of them had zero idea of "Operation Ajax" since most of them were well under thirty, even twenty-five, in 1978/1979. And they were radicalized islamists, led by a fundamentalist mullah, oil was not even on their radar. They didn't even oppose the Shah because he was somewhat friendly to the U.S., they opposed the Shah because he was Persian, and relatively modern and progressive, instead of a fundamental islamist.
The Iranian "revolution" wasn't even comprised of a majority of Iranians, but rather a very vocal and violent minority of islamists.
