This paper encompasses the first chapter of my dissertation, which examines the history of the political activism of Jewish-American immigrants within the Israeli ultra-nationalist movement since 1967. My presentation will focus on the first decade of 1967-1977, when many Jewish-American immigrated to Israel and made their first contacts with the "new frontier" of the newly occupied territories. In addition to discussing the statistical and demographic make-up of these immigrants, this chapter focuses on the untold history of their first exposure and activism within the early years of the Israeli settler movement. The paper highlights the role of immigrant organizations (AACI/AACA), Zionist youth movements in the United States, the Jewish Agency/WZO, and the international outreach arm of Gush Emunim in encouraging Jewish-American immigrants to visit and settle in the West Bank, Gaza Strip, and Sinai. This chapter also chronicles the early activism of Jewish-American immigrants as founders of garinim (seed colonies) of new settlements, including Yamit, Hebron/Kiryat Arba, and Tekoa between 1967 and 1977. Lastly, I examine the way in which Jewish-American immigrants began to take a more active role in the ultra-nationalist camp as a whole by introducing American-style discourses and tactics into the movement. As a part of my dissertation, I hope it will present an original contribution to our knowledge of the Israeli ultra-nationalist movement and our understanding of U.S-Israel relations from a cultural perspective.
