Efraim Karsh, professor of Mediterranean Studies at King's College London, writes that Morris engages in what Karsh calls "five types of distortion". According to Karsh, Morris "misrepresents documents, resorts to partial quotes, withholds evidence, makes false assertions, and rewrites original documents... tells of statements never made, decisions never taken, events that never happened ... at times [he does not even take the trouble to provide evidence... He expects his readers to take on trust his assertions that fundamental contradictions exist between published accounts and the underlying documents...he systematically falsifies evidence. Indeed, there is scarcely a document that he does not twist. This casts serious doubt on the validity of his entire work." In addition he claimed to expose a serious gap between Morris' text and the original diary of Ben-Gurion, the first prime minister of Israel.
