Should or can Turkey join the European Union (EU)? This paper argues that there are three alternative scenarios of the EU decision to grant membership to Turkey: 'privileged relationship offer,' 'wait and see attitude,' and 'start of full membership negotiations.' It then gauges each alternative path, and argues that the most likely scenario is a decision to start the negotiations, followed by the scenario of 'wait and see.' The EU decision will be conditioned by its future vision of global governance and the role foreseen for Turkey inside, outside or at the margin of it. The paper concludes that the EU decision will have significant implications for the future of relations between Europe and Turkey on the one hand, and Europe and the Islamic world on the other.
