We live in an era when the American government portrays Iran as a threat to the world, as a member of the Axis of evil, as theocracy in which every Friday evening millions chant, "Death to America" in houses of worship, a country with which it is impossible to have normal relations. Is this all true? and if it is partially true, then what lies behind it?
The author argues that we need to understand what has happened in Iran over the last 2,500 years to understand what is happening today, for this history lives in the collective subconsciousness of Iranian society. He starts with the pre-Islamic era when Persian power extended all the way to the Mediterranean and when the Persians believed in Zoroastrianism. He then describes how the Persian empire decayed and was run over by Arabs under the banner of Islam, Persia adapted. Its people converted to Islam voluntarily (this is an interesting insight, that the Arabs were not proselytizing), but they created their own version of Islam - Shia - and how Shia Islam builds on Zoroastrianism. He then describes how Shia Islam has been a central tenet of Iran for over thousand years, and what sets Iran apart from rest of the Islamic world.
Interestingly, Polk makes a case that throughout history, Iran's rulers have required the consent of its people to stay in power. It society has different power centers - Shia religious leaders, the military class represented by tribes and militias in the past, and merchants - and these power centers have competed for power. Over centuries, the ruling regime obtained the people's consent in different ways - by winning wars, by establishing royal lineage, or based on religion, sometimes all of these. According to Polk, even in the Islamic Republic, elections are relatively fair, and the political leadership is accountable to the people.
