The 1953 Iranian coup strengthened the Iranian monarchy and overthrew Mossadegh the Prime Minister. And Britain would have got Mossadegh out anyway—they were fighting on the ownership of oil installations. If a British-backed coup ended up failing, Iran would probably have been pushed into the arms of Soviet Union. (Just like Nasser in Egypt after the Suez crisis)
We could have ended up with an Arab conquest of Israel—if Iran allowed Soviet forces to move into Soviet-leaning Iraq and Syria in 1967.
