You might want to revisit your understanding of the events in Iran in 1953. Furthermore, if you study the actual history of Iran you’d find that reactionary elements within Iran began the unrest in 1906 as the feudal structure of the Qajar Dynasty was coming to an end.

Regardless of what happened in 1906, Iran had a democratically elected government in 1953. Great Britain was concerned they would lose influence if the new government nationalized the oil fields, and got the US to help instigate a coup to remove the government.
Trump inherited this mess. Kudos to him for wanting to fix it, but either he is receiving some bad, even dishonest, advise, or he has an ace up his sleave. I hope it's the latter, for our sake as well as Iran's.
