Iran still flies F-14s.
In fact, they made the news a couple weeks ago:

It's admittedly bizarre to have our old aircraft operated by a foreign adversary that's supposedly intercepting our newer, unmanned aircraft.
The "spy drone" is likely MQ-9, which is large, slow and somewhat clunky, and routinely shot down by the Yemeni Air Force.
This is nonsense. You should read a history of Iran or at least the wikipedia page. https://en.wikipedia.org/wiki/Mohammad_Reza_Pahlavi
Reza played the powers against one another. At times the US dictated what happened. At times Reza had more leverage and dictated terms to the US. It certainly was not a US vassal and did plenty of things that annoyed the US. Heck, the US didn't even control the oil industry in Iran, Britain did.
MI6 and Mossad were as involved in the 1953 assassination of Mossadegh as the CIA.
Did you read it?
