That's just wishful thinking on your part. Every iranian i speak to curses their regime and praise trump and netanyahu. Their level of support for the people bombing their country is incredible.
We've seen this with the Cuban diaspora, who were heavily anti-Castro. I mean let's just consider for a second who would flee a regime? Batista loyalists, mostly. So is it any surprise? This myth-making has become almost comical. Ted Cruz, for example, hates communism because Batista tortured his father [1].
The Persian diaspora is really no different. It's incredibly reactionary [2][3]. They were implicated in the attack on pro-Palestinian protesters at UCLA, for example.
The US and Israel are deeply popular in Iran. These are the same people who killed almost 200 school girls by double tapping a school. Is that really a surprise?
