The paper, written for a joint project of the Gulf Research Center in Dubai and the Bertelsmann Foundation, explores whether the lessons from the transformation of Europe from a conflict formation into a security community could be transferred to the Persian Gulf region. It records and analyses the European experience with “security models” actually applied such as balance-ofpower, nuclear deterrence, arms control and confidence-building, democratic peace, regional integration etc. as well as various alternative models such as common security and defensive restructuring of the armed forces. It further analyses the structure and dynamics of the Persian Gulf region, finding few of the European models to be really applicable. It concludes with outlining two different scenarios for the development of the region after the invasion and occupation of Iraq.
