For instance, the differences of opinion between Rubinstein and Wyman on the issue rest principally on Rubinstein's argument that the Zionist Jews in Palestine (such as David Ben-Gurion) are primarily to blame for not giving refuge to European Jews in Palestine, rather than putting the responsibility on the British authorities or the Palestinian Arabs who violently opposed such rescue efforts. Some historians have taken Rubinstein and other Wyman critics to task for such assertions, and have directly attacked these criticisms of Wyman's positions as unscholarly "polemic."
