The Shah began to search for a new prime minister, one who was a civilian and a member of the opposition. On 28 December, he secured an agreement with another major National Front figure, Shahpour Bakhtiar. Bakhtiar would be appointed prime minister (a return to civilian rule), while the Shah and his family would leave the country for a "vacation". His royal duties would be carried out by a Regency Council, and three months after his departure a referendum would be submitted to the people deciding on whether Iran would remain a monarchy or become a republic. A former opponent of the Shah, Bakhtiar became motivated to join the government because he was increasingly aware of Khomeini's intentions to implement hard-line religious rule rather than a democracy. Karim Sanjabi immediately expelled Bakhtiar from the National Front, and Bakhtiar was denounced by Khomeini (who declared that acceptance of his government was the equivalent of "obedience to false gods").

We say that the end of the United States is imminent, whether Bin Laden or his followers are alive or dead, for the awakening of the Muslim umma (nation) has occurred.
