However, due to the unwillingness of Farouk to change, the project moved to support his overthrow. Roosevelt secretly met with the Free Officers Movement, a group of nationalist revolutionaries in the army of Egypt and Sudan that was opposed to the monarchy, and the United Kingdom's continuing miliary presence in the country. The Free Officers, led by Mohamed Naguib and Gamal Abdel Nasser, had already been planning to overthrow Farouk, and launched their revolution with a coup d'etat against the King on 23 July 1952. Miles Copeland states that the US provided support for the revolutionary government to be "coup proof", helping in establishing the new General Intelligence Agency (Al-Mukhabarat el Aam), modelled after the American Central Intelligence Agency, as well as German advisors who had served in German military intelligence, including the Abwehr, to create the new security apparatus.
