Former Egyptian President Hosni Mubarak dismissed el-Nabawy Ismail as Minister of Interior and appointed Hassan Abu Basha instead, where Mubarak's policy then was to change and build the base of security. Mubarak took over power without struggle, just as former President Gamal Abdel Nasser and Anwar Sadat did. Mubarak announced he will not change any leaders, officials and ministers, only the Minister of Interior. Mubarak found it important to dismiss Ismail and appoint Abu Basha, after Mubarak appointed a Prime Minister because the position was empty. A few hours after Sadat's assassination, all regime officials agreed to nominate Mubarak the President of Egypt. Mubarak spent six years as vice president for Sadat. The presidency in Egypt was like a pyramid, the president at the top. Gamal Abdel Nasser and Anwar Sadat were at the top but Hosni Mubarak was different. Abdel Nasser spent two years in struggle for power. There were many struggles and tension from July 1952 to March 1954. Mohamed Naguib was president of Egypt until Abdel Nasser took authority from him in 1954. At the time, Abdel Nasser confronted everyone, including his opponents, old regime officials and officers. Everything settled after the nationalization of the Suez Canal and the Suez War, which made him the greatest Egyptian and Arab leader until the setback in 1967. As for Anwar Sadat, he started his era with a struggle with forces who tried to impose their influence, rigid corners in Abdel Nasser's regime. But the imposers resigned and Sadat started his reign after he got rid of his opponents, following the Machiavelli way. Sadat announced the revolution of correction and he got rid of opponents who believe him weak. When Abdel Nasser chose Sadat as vice president, Sadat's opponents considered Abdel Nasser's choice a mistake or coincidence. But Sadat proved himself to be an intelligent president, able to manipulate his opponents. From May 1971 to October 1973, Sadat faced many doubts in his skills and ability to win the war. But he won in the October War in 1973 and was able to promise people with democracy and development. Hosni Mubarak took over presidency without any struggle when Sadat was assassinated during a military parade celebrating the opening of the Seuz Canal. The assassination facilitated the transfer of power with ease to Mubarak. Mubarak became president 8 days after Sadat's assassination. Sadat didn't live to see his dream of retrieving Sinai back come true, even after his visit to Al-Qods and signing the Camp David treaty. After this treaty, most Arab countries cut their relations with Egypt. There weren't any clear details about the group that assassinated Sadat, according to the then Minister of Interior, Hassan Abu Basha. Abu Basha was able to bring stability and security by arresting members of el-Jihad group, who were later trialed. Mubarak didn't find it necessary to struggle for authority since Sadat's men supported Mubarak as president. Mubarak didn't show any desire to change them since they supported him.
