This paper examines the processes by which Jewish Americans become involved in Palestinian solidarity activism. In Jewish community centers, schools, and synagogues throughout the United States, American Jews are being socialized to identify as members of a Jewish diaspora that centers the state of Israel as the Jewish homeland. This political socialization is upheld by economic and political forces that incentivize American Jews to support the state of Israel, which in turn, leads Jewish Americans to side with Israel in its conflict with the Palestinians. Despite this context, a growing contingent of American Jews are mobilizing against the state of Israel through organizations like Jewish Voice for Peace (JVP). This paper analyzes data from a survey of JVP’s national members in order to understand the factors that lead American Jews to become anti-Zionists. My results show that Jewish members of JVP experienced turning points in their views on Israel at roughly the same rate as non-Jewish members. The data further suggest that most JVP members, both Jewish and non-Jewish, overwhelmingly attributed the cause of their turning points to historical events and the media’s portrayal of those events. These findings suggest that contrary to past research, the process of ideological transformation on Israel/Palestine appears to be quite similar for both Jewish and non-Jewish activists in these organizations, which suggests the relative marginality of Jewish identity in these activists’ anti-Zionism.
