本文以土耳其以外的三個行為者－美國、伊拉克、歐盟－作為解釋近年來土耳其政府與境內庫德族關係改變的主要因素。美國與伊拉克的衝突造成伊拉克境內庫德族處境艱難，卻造就伊拉克庫德族與美國政府站在同一陣線的機會，觸動到土耳其政府的敏感神經。相對於美國 傳統的權力觀，歐盟對於其他國家的重塑力在土耳其與庫德族的關係演變中獲得了彰顯。在此錯綜複雜的多邊關係中，美國與伊拉克庫德族的共同利益以及歐盟與土耳其庫德族的共同利益交織出土耳其政府愈來愈有限的庫德族政策選項。

This article looks into the changing relationship between the Turkish government and the Kurdish population within Turkey. In explaining changes in this relationship over the past twenty years, the roles of three external actors － the U.S., the Iraqi Kurds, and the EU － are brought into consideration. The Iraqi War prompted the U.S. government to have a cozy relationship with the Iraqi Kurds, a development that alarmed the Turkish government. In contrast with the conventional approach to power by the American government, the Europeans have successfully modified the behavior of the Turkish government, with the improvement of Turkish Kurds’ human rights situation being one example. The combined effects of all these external actors on Turkey are the increasingly limited options available to the government in terms of its policy towards the Kurds within its border.
