Egyptian President Anwar Sadat – whose policies included opening Egypt to Western investment (infitah); transferring Egypt's allegiance from the Soviet Union to the United States; and making peace with Israel – released Islamists from prison and welcomed home exiles in tacit exchange for political support in his struggle against leftists. His "encouraging of the emergence of the Islamist movement" was said to have been "imitated by many other Muslim leaders in the years that followed."  This "gentlemen's agreement" between Sadat and Islamists broke down in 1975 but not before Islamists came to completely dominate university student unions. Sadat was later assassinated and a formidable insurgency was formed in Egypt in the 1990s. The French government has also been reported to have promoted Islamist preachers "in the hope of channeling Muslim energies into zones of piety and charity."
