Progressive Israelis strive for a society that is "Jewish" as a reflection of its majority cultural influences rather than by law. Even now, Israel has some bi-national and bi-cultural characteristics. Israel runs to the rhythms of both the Jewish and Muslim calendars. For example, its weekends are Fridays and Saturdays, the Muslim and Jewish Sabbaths. And although Hebrew is the preeminent tongue, Arabic is the second of Israel's two official languages, and there is some Arabic programming on public television and radio.In the fall of 2007, the NIF brought Israeli speakers to a series of forums around the United States to examine Israel's ethnic, cultural and economic diversity. This was discussed in the context of a "Jewish state" and how this concept resonates, if at all, with American Jews. Eliezer Yaari, the NIF's executive director in Israel, stated a preference for describing Israel as a "state of Jews" rather than the more ideological construct of the "Jewish state."
