Book excerpt: The Middle East has been the arena of three cataclysmic events since 1979 - the Iranian Revolution, the Iran-Iraq War and the Gulf War. All of these have brought about major changes in the inter-regional politics and relations between Middle East countries and the outside world. This book seeks to analyze the impact of these events on Iranian-Arab relations. The authors examine Iran's relations with the Arab states of the Gulf in detail and sheds light on the changing patterns of Iranian-Egyptian and Lebanese relations.
