Israel actively sought a return of Jewish peoples from Arab lands in the 50's and 60's. This is no secret, and even Israeli historians don't pretend that this wasn't a serious campaign. Iraq is a classic case, where mossad actively fostered the 'return' of Iraqi jews through a campaign of bombing synagogues, embarrassingly exposed. There was a memo.

I accept that the environment has become more and more difficult for Jewish people in Arab countries, but this owes a lot to the history that took place during that period where the palestinian demographic crisis polarised the region.
Nevertheless, it's not uncommon for arabs to state that the sephardic Jews fitted in well with the arabs, but the ashkenazim , due to their european trappings and outlooks were a much more difficult prospect. Iranian jews are often held up by arabs as being exceptionly easy to have dealings with for example. Iran allows unimpeded travel for Iranian jews to visit relatives in Israel.

Consider this; in the space of only 30-49 years the region of Palestine was turned on its head demographically by a european influx. That causes trepidation anywhere. as much as I believe in Israel as an entity, I don't see anything unusual about there being such a strong reaction to such a drastic cultural change in the area.
