This chapter examines how nationalism, religious claims, and settler colonialism enmesh within Zionism and demonstrates how their interaction played a major role for Israeli academia and politics in sidelining or obfuscating settler colonialism as an appropriate frame of analysis for Zionism’s encounter with the Palestinians. The chapter makes three main arguments: first, that while settler colonialism is an obvious framework for analyzing and understanding the unfolding of the Zionist project in Palestine, the framework has been obscured by highlighting the connection between Jewish nationalism and religious claims; second, that the steady rise in religious encroachment into institutions and the public sphere in Israel is rooted in the need for legitimation (grounded in religious claims) in face of rising Palestinian resistance to the expansion of the settler-colonial project from Israel to the West Bank; and third, that while secularization was possible in other settler-colonial contexts such as South Africa, Northern Ireland, and North America, it is impossible to achieve secularization within a Zionist regime. Rather, for secularization and democratization to take place, Israel has to recognize the settler-colonial reality of the Zionist project, a recognition that will make it possible to free Israeli Jewish nationalism from religionism and work toward decolonization.
