The imposition of the British Mandate over Palestine in 1922 put the Zionist leadership between a rock and a hard place, between its declared allegiance to the idea of Jewish sovereignty and the necessity of cooperation with a foreign ruler. Eventually, both Labour and Revisionist Zionism accommodated themselves to the new situation and chose a strategic partnership with the British Empire. However, dissident opinions within the Revisionist movement were voiced by a group known as the Maximalist Revisionists from the early 1930s. This article analyzes the intellectual and political development of two Maximalist Revisionists – Yonatan Ratosh and Israel Eldad – tracing their gradual shift to anti-Zionist positions. Some questions raised include: when does opposition to Zionist politics transform into opposition to Zionist ideology, and what are the implications of such a transition for the Israeli political scene after 1948?
