I think it's a similar quandary with Arabs, minus the shared religion of course.
I'm Tunisian and I consider myself Arab, but many other Tunisians consider themselves (ethnically) Maghrebi and/or Amazigh. Tunisia and the remaining Maghrebi countries are part of the Arab League, though.
I'm sure it's even more complicated for Tunisian Jews :P
Even, in Tunisia, to quote Wikipedia: "In 1948 the Jewish population was an estimated 105,000, but by 2013 only about 900 remained"...
That said, the 2014 Tunisian constitution and its protections for freedom of religion was a huge step forward, and gives me a good bit of hope for the future.
