O.k., it wasn’t this day, but it was August 19, 1953. Laurence Lewis has a good summary up discussing the American-engineered coup in Iran back then.
The short version is that Iran’s fledgling democracy had produced Mohammed Mossadegh, making him prime minister. He was making rumblings about nationalizing the Anglo-Iranian Oil Company (what would become BP). The Brits didn’t like that, and the Americans went along with them. So, the CIA tasked Kermit Roosevelt (grandson of Teddy) with deposing Mossadegh. He did so successfully and the second Shah returned to power and brutally put down his secular opposition for the next couple of decades. When he was engaged in his brutality, the Iranians remembered that they had American meddling to thank for it. When the revolution against the Shah came, it took the form of a hyper religious movement led by the Ayatollah Khomeini and, the early years, featured American hostages.
Our whole relationship with the Middle East is seemingly colored by that 1953 coup. I don’t know enough about the history to know whether we would likely have had friendly relations with that part of the world in the absence of the coup. But it certainly didn’t seem to help anything.
Our relationship with the Middle East begins with the Versailles Treaty negotiations in 1919. The late President Wilson made more promises than he was able to keep (a US political tradition from WAY back) and most of the colonial world, plus Asia, remembered. Most Presidents have done little better since then. We have been paying a price, more often than not, ever since then.
