 As the highest-ranking official responsible for military planning, Dayan may bear part of the responsibility for the Israeli leadership having missed the signs for the upcoming war.In the hours preceding the war, Dayan chose not to order a full mobilization or a preemptive strike against the Egyptians and Syrians.He assumed that Israel would be able to win easily even if the Arabs attacked and, more importantly, did not want Israel to appear as the aggressor, as it would have undoubtedly cost it the invaluable support of the United States (who would later mount a massive airlift to rearm Israel).
