Gamal Abdel Nasser, President of Egypt, believed that during the Suez Crisis, the Egyptian Armed forces had defeated the combined forces of Israel, the United Kingdom and France, when in reality it was the pressure from the United States which was the decisive factor. This gave Nasser an inflated view of the strength of his forces, so when the Six Day War started, he believed that Egypt would be able to defend itself against Israel's advance. However, this overconfidence, as well as false "victory" reports which brought Jordan and Syria into the war, proved to be its downfall as Israel managed to defeat the Arab forces and conquered their territory as well.
