This is even more laughable when you consider that there are native Jewish speakers of the local idioms, accents and dialects from many Arabic-speaking countries: North Africa, Yemen, Syria, etc (and don't forget Persian Jews who are native speakers of Farsi spoken in Iran).
I wonder if the FBI would also exclude David Pryce-Jones? I don't think he's a Jew, but he certainly speaks Arabic idioms like a native, and is very antiIslamist terrorism.
And its ludicrous to say that there are other factors in turning away Arabic-speaking Jews because such factors would never rationally apply to EVERY Jew applying.
