Defining Christian Zionism as conservative Christian support for the state of Israel, and an influential political force, especially in the United States, this article outlines four antinomies of such a position. Firstly, although Christian Zionism argues that it is purely theological, that it follows God?s will irrespective of any politics, and although mainstream Zionism is resolutely political, we argue that such a separation is impossible. Indeed, mainstream Zionism cannot avoid being influenced by Christian Zionism?s political agenda. Secondly, despite the efforts by mainstream Zionism to use Christian Zionism in order to influence US foreign policy in the Middle East, mainstream Zionism is playing with fire, since Christian Zionists wish to convert or annihilate all Jews. Thirdly, Christian Zionism is the ultimate version of anti-Semitism, for it wishes to get rid of Arabs (as hindrances to the Zionist project) and then dispense with Jews. (Both Arabs and Jews are by definition Semites.) Finally, since Christian Zionists are fundamentalist Christians, they must take the Old and New Testaments at their word. However, this position is impossible to hold, and in order to resolve the tension they must resort to the violence of the final conflict, Armageddon.
