I think you underestimate how much Iranians hate their current regime..
Do you have some solid sources on the ground to the contrary?
My professor from my graduate program and his family are all Iranian. It's no surprise that they anti-regime: his wife's uncles were generals in the Shah's army, and were "disappeared" during the Revolution. They've been living in Japan for ~40 years. Hardly indicative of the opinion of the "man on the street" in Tehran, Isfahan, or Mashhad.
Some circles might have only pro-Trump Americans. Others might only have anti-Trump Americans. And yet your experience is all-knowing? With 15 families? Outside of Iran (presumably).
