Magnes returned to the United States in April 1948 to participate in an anti-partition campaign . At the time he left , his position at Hebrew University was in jeopardy , as more staff moved against him due to his views . According to Israeli historian Benny Morris , the Hadassah medical convoy massacre of April 13 , 1948 , was " in effect the final nail in the coffin of Magnes ' binationalism . It was not that he publicly recanted . But he understood that it was a lost cause - and that his own standing in the Yishuv had been irreparably damaged . " At the funerals of the victims , eighteen staff members from Hebrew University signed a petition protesting Magnes ' view . The campaign was led by Professor Shimon Fritz Bodenheimer , who called Magnes a " traitor "
