The essay looks at three spheres in which ideological bias and political activism work to delegitimize the State of Israel by maligning Israel and Zionism in mainstream British public discourse. Postcolonial theory is one weight against any objective treatment of the Jewish state. The demonization of Israel in the press draws on conspiracy theories and stereotypes familiar from anti-Semitic tropes. British Jews are fairly supportive of Israel, though divided on solutions to the Arab-Israel conflict, however a small group of anti-Zionist Jews assert their moral stance "as Jews" by defaming Israel's allegedly criminal activities. The analysis of public discourse in Britain in the first decade of the twenty-first century raises disturbing questions about the complex relationship between the anti-Israel campaign and latent anti-Semitism on the left and the right, and draws attention to the local context of race relations as well as the global Jihad against Israel and the West.
