February 1, 1979, an elderly man, a darkly austere imam, dressed in a black robe, stepped out of a chartered aircraft at Tehran airport to a rapturous reception from a crowd of nearly one million Iranians. The world had no idea that this man, Ayatollah Khomeini, would soon disrupt the lazy rhythm of the global order to which the western world had got so fond of since the end of the Second World War. The Ayatollah, who would soon elevate himself to the status of the Supreme Leader, was untutored in the norms and rules of the civilised world. He was deeply resentful of a global order that had allowed a despotic Shah to write his own rules of oppression and repression.
