Why should anyone be a Zionist, a supporter of a Jewish state in the land of Israel? Why should there be a Jewish state in the land of Israel? This book seeks to provide a philosophical answer to these questions. Although a Zionist need not be Jewish, nonetheless this book argues that Zionism is only a coherent political stance when it is intelligently rooted in Judaism, especially in the classical Jewish doctrine of God's election of the people of Israel and the commandment to them to settle the land of Israel. The religious Zionism advocated here is contrasted with secular versions of Zionism that take Zionism to be a replacement of Judaism. It is also contrasted with versions of religious Zionism that ascribe messianic significance to the State of Israel, or which see the main task of religious Zionism to be the establishment of an Israeli theocracy.
