Many of Morris's critics cling to the tenets of "Old History", the idea of an Israel born untarnished, a David fighting the Arab Goliath, Shlaim writes. He argues that these ideas are simply false, created not by historians but by the participants in the 1948 war, who wrote about the events they had taken part in without the benefit of access to Israeli government archives, which were first opened up in the early 1980s. Another group of Morris's critics such as Avraham Sela, as well as historians on the left such as Ilan Pappé, argue that he has relied too heavily on Israeli sources and hardly at all on the Arabs. Norman Finkelstein, Nur Masalha and others argue that Morris has been too soft on the Israelis, often ignoring the force of his own evidence. Efraim Karsh alleges that Morris has distorted source material, an allegation not accepted by other historians.
