Spring 2005- (Published in Vol. 4, No. 1 issue of Turkish Policy Quarterly.) Historically, US-Turkish relations have been deeply affected by events in Cyprus ever since the 1963 crisis, and especially the 1974 coup and invasion. Since the Greek Cypriot rejection of the Annan Plan in April 2004,decades of vigorous diplomatic efforts by the US State Department to resolve the Cyprus problem have ground to a near halt. Turkish and Turkish Cypriot support for the Annan Plan, which was strongly endorsed by the European Union, have also diminished the impact of Cyprus developments on US-Turkish relations. Separately, however, the relationship is in a state of severe disrepair in the wake of Turkish misconceptions about US aims and actions in Iraq and the broader Middle East, as well as the profound mutual mistrust that has only hardened since the March 1, 2003 Turkish parliamentary vote rejecting a Turkish role in the Iraq invasion. At this point, even a historic and welcome solution to the Cyprus problem will have little positive influence on US-Turkey relations, which may have entered a transformational phase with uncertain outcomes.
