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. Rabin, a future Chief-of-Staff, later wrote that Israeli intelligence had never been in worse shape. Laskov had lost all faith in the head of military intelligence, Chaim Herzog, but was prevented from dismissing him by Ben-Gurion. The crisis influenced Israeli national security policy, defining any Egyptian military build-up along its border as unacceptable, while the Israeli intelligence community took extensive measures to improve its collection capabilities. The crisis has come to be regarded as a "trial run" for the events that led to the 1967 Six-Day War. Israel and Egypt had drawn very different conclusions from the crisis. While the former came to believe new and restrictive rules had been set in place, the latter believed that it had gained more room to maneuver, able to deter Israel by the deployment of forces without the actual necessity of going to war. When, in 1967, Nasser once again moved the Egyptian army into the Sinai following renewed reports of tension along the Israeli-Syrian border, many in the IDF General Staff were reminded of events in 1960. Both Rabin and Weizman, in their respective memoirs, noted that events in 1967 at first seemed like a repeat of the Rotem crisis, and that lessons drawn from the first were applied in the second. There was initially little thought of war. In 1992, retired Major-General Jamal Mat'lum, Director of the Egyptian Army's Center for Strategic Studies, also noted the role played by the Rotem Crisis in Egyptian decision making in 1967:  Yet while the Egyptian deployment in 1960 had been discreet, in 1967 it was carried out in full view of the public. The new deployment evoked widespread enthusiasm in the Arab world, leaving the various players with less room to maneuver. Nasser demanded the withdrawal of UNEF and the crisis soon gathered a momentum of its own, eventually leading to war.
