Beyond my comprehension to reason why a wealthy Jewish family elects to remain in Iran.
It is hard to leave the life one knows. Especially if the family has resources.
Somebody has to handle all those cash transactions with the banks in England.
Lured by a schizophrenic madman: one minute wanting to wipe jews off the face of the map, the minute after having a conference with jews...
Because they don't want to give everything they own and have worked to build for generations to those savages. Same thing happened in Germany. I've known quite a few Iranians, most of them were perfectly decent people. Their country is in the hands of the worst and most viscous fanatics. Iran doesn't have medieval cathedrals decorated with Judensau. I suspect that the average Iranian is far less antisemitic than the average German or the average Arab. I spent 16 months in Shermany, and it was not at all unusual for people one meets on the train or in passing to go wander off into antisemitic babble. You barely need to scratch an Arab to be scalded by steaming antisemitism. I never got that from any Iranian I have known.
