People of many races, colors and ethnic backgrounds live in Israel. It is pointed out that Israeli Jews come from a wide variety of ethnic backgrounds. In the 1930s, ideas of a 'population exchange' of Arabs and Jews between Arab states and Israel were actually popular among Zionists. In practice, most Jews living in Arab Nations in 1948 have currently left Arab countries: 2/3 have moved to Israel. Zionism allows Arabs, Druze, Bedouin and other non-Jews to live in Israel as well, although by most interpretations it requires a Jewish majority to be established.
