In his updated "The Birth of the Palestinian Refugee Problem Revisited" (2004), Morris answers critics of the first version and adds material from the opening of new Israeli government archives. He writes that the contents of the new documents substantially increase both Israeli and Palestinian responsibility for the refugee problem, revealing more expulsions and atrocities on the Israeli side, and more orders from Arab officials to the Palestinians to leave their villages, or at least to send their women and children away. Morris writes that his conclusions are unlikely to please either Israeli or Palestinian propagandists, or "black-or-white historians".
