I've changed this to "emigrated or were expelled", which closely follows the wording in the article linked to - Jewish exodus from Arab lands. That article would seem a more logical place to seek wording than a treatment of Nakba: to suggest that the same sort of wording should be used for two different events without any rationale is a bit peculiar. However, it's clearly true that many of these Jews did "flee". Perhaps there is some better way of phrasing it, without sacrificing accuracy. I agree with the commenting out of the speculative sentences about illegal immigrants.  | Talk
