The three major Middle Eastern religions are significantly different in their relations with the state and their attitudes to political power. Judais… - Bernard Lewis

In talking of the Christian world, in English and, I suppose, in all the other languages of the Christian world we use two terms: Christianity and Christendom. Christianity means a religion, in the strict sense of that word, a system of belief and worship and some clerical or ecclesiastical organization to go with it. If we say Christendom, we mean the entire civilization that grew up under the aegis of that religion, but also contains many elements that are not part of that religion, many elements that are even hostile to that religion. Let me give one simple example. No one could seriously assert that Hitler and the Nazis came out of Christianity. No one could seriously dispute that they came out of Christendom. In talking of Islam, we use the same word in both senses, and this gives rise to considerable confusion and misunderstanding. There are many things that are described as part of Islam, which are indeed part of Islam, if we take the word as the equivalent of Christendom, but are very much not part of Islam are even alien or hostile to Islam if we take the word Islam as the equivalent of Christianity. I think this is a very important point, which one should bear in mind.

Ultimately, the struggle of the fundamentalists is against two enemies, secularism and modernism. The war against secularism is conscious and explicit, and there is by now a whole literature denouncing secularism as an evil neo-pagan force in the modern world and attributing it variously to the Jews, the West, and the United States. The war against modernity is for the most part neither conscious nor explicit, and is directed against the whole process of change that has taken place in the Islamic world in the past century or more and has transformed the political, economic, social, and even cultural structures of Muslim countries. Islamic fundamentalism has given an aim and a form to the otherwise aimless and formless resentment and anger of the Muslim masses at the forces that have devalued their traditional values and loyalties and, in the final analysis, robbed them of their beliefs, their aspirations, their dignity, and to an increasing extent even their livelihood.

The Iranian revolution was a real revolution, not just a coup d'etat or a putsch or whatever. It was a genuine revolution in the sense that the French and the Russian revolutions were revolutions. It brought a massive change, social, economic, ideological not just a change of regime. Like for the French and Russian revolutions in their day, Khomeini had had a tremendous impact everywhere they had a shared universe of discourse, that is to say, the Muslim world. Just as the French and Russian revolutions in their day, and for some time after, had such an impact, so did the Iranian revolution, and it was not limited to the Shi'a world.
