This statement is correct. The official number of Arabs that fled or that were expelled during the Israel-Palestine War (1948) reach 711,000 people. On the other hand, the Jews that were living in Arab countries, that had not assaulted their country people, abandoned their homes reaching nearly 900,000 displaced people. In 1948, there were 265,000 Jews in Morocco and in 1976 there were 17,000 left. In Algiers, during the same period there were 140,000 and then 400, in Tunisia there were 105,000 and then 200 left. In Libya from 38,000 to 20, in Egypt from 200,000 to 200. Iraq 135,000 to 400, Syria 30,000 to 4,350, Lebanon 55,000 to 1,000 and in Yemen 8,000 to no one left. So, in total, in 1948 there were 880,000 Jews living in Arab countries, then in 1976 there were only 25,620 people left, and at present, in the same countries, there are only 7,650 people.
In Iran, since the Islamic revolution, the situation of the Persian Jewish community has been undermined. In 1990, 55,000 Jews left the country: 30,000 went to the US, 20,000 to Israel and 5,000 to Europe. However, the community has relative cultural autonomy, so in general, they are not victims of harassment or insults by the Muslims. The community has a representative in the Iranian parliament, Morris Mutmad. In July 2012 there were approximately 8,756 Iranian Jews left. With the establishment of the State of Israel, and even before, most of the Jews of Turkey immigrated to Israel, a total of 55,500. Today there are only 17,400 Jews in Turkey. Until November 2003, for example, 101 of the 681 resolutions of the UN on the Middle East conflict concerned the Palestinian refugees directly. Not one of the resolutions addresses the Jewish refugees from the Arab countries, which were more, according to the numbers.
