I was actually trying to say that there are Muslim countries who are welcoming to Jews in my title. I didn't want to suggest that all Muslim countries discriminate against Jews.
Its true that Iran is unique in its really awful government, but many other Muslim countries are not particularly welcome to Jews.
Turkey is actually one of the countries which does have a large-ish Jewish population who live there fairly happily.
Morrocco has a smallish community, other countries have almost none.
Here is a really interesting article about the Jewish community in Iran from a few years ago. @mouthpipette it might answer some of your questions. https://forward.com/news/31926.....ched/
