On New Year's Eve, 1977, on a state visit to Iran, President Jimmy Carter toasted Shah Mohammad Reza Pahlavi, King of Kings, Light of the Aryans, Shadow of God on Earth, praising Iran as "an island of stability " due to "your leadership and the respect and admiration and love which your people give to you." Iran had the world's fifth largest army and was awash in billions of dollars in oil revenues. Construction cranes dotted the skyline of its booming capital, Tehran. The regime's feared secret police force SAVAK had crushed communist opposition, and the Shah had bought off the conservative Muslim clergy inside the country. He seemed invulnerable, and invaluable to the United States as an ally in the Cold War. Fourteen months later the Shah fled Iran into exile, forced from the throne by a volcanic religious revolution led by a fiery cleric named Ayatollah Khomeini. The ensuing hostage crisis forever damaged America's standing in the world. How could the United States, which had one of the largest CIA stations in the world and thousands of military personnel in Iran, have been so blind?
