The Israeli educational system has historically affirmed the Zionist doctrine that Jews can only live a physically and spiritually secure life in the State of Israel, minimizing successful Diaspora Jewish communities like those in North America. Indeed, a 2005 report conducted by the American Jewish Committee found that only 14% of Israeli high school teachers said the topic of U.S. Jewry had been taught in their schools during the three years preceding the study. This thinking is still influential among many Israelis, but some are gradually favoring a greater understanding of American Jewry.
