Levene's work and research focuses on genocide, Jewish history and anthropogenic climate change.
He stated that the book makes a valuable contribution, although the study's foundational assumptions are questioned.
[2] In this 1992 essay, Levene followed the people behind the Balfour declaration which during the First World War gave birth to the British Mandate of Palestine and to what later became the state of Israel.
He wrote: "Barbara Tuchman in all seriousness proposed that 'the English Bible was the most important single factor'.
"Levene discovered that an anti-Zionist Jew, Lucien Wolf, had actually proposed the idea to the "then clearly anti-semitic" British Foreign ministry and that it was accepted precisely because of that, with the British believing that supporting the Zionists would bring "World Jewry" and especially the Jews in the United States to side with Britain and actively enter the war against Germany (and the Ottoman Empire who ruled Palestine at the time).
