Although neglected in the historiography of the Arab–Israeli conflict, the Rotem Crisis was the most serious challenge to Israel's doctrine of deterrence in the years between the Suez Crisis and the Six-Day War. Haim Laskov described it as the most dramatic event of his tenure.[1] It revealed deficiencies in the Israeli intelligence community, which failed to provide warning of an imminent threat, and in the IDF's ability to translate such warnings into immediate action. Although intelligence had suggested Egyptian forces were on the move, a week went by before the full extent of the Egyptian deployment came to light and countermeasures were taken.
