This article discusses the changing relations between the United States and Turkey in light of Turkey's contemporary foreign policy that often challenges American interests. More specifically, it adopts a comparative approach to examine the variables that determine the course of US reaction when unwanted policy shifts take place in the Middle East. To this end, apart from Turkey, the article examines two more cases: US relations with Egypt in the 1950s, and with Iran right before, during and after the 1979 revolution. The comparative analysis reveals that the case of contemporary Turkey has been more similar to the historical case of Egypt, which explains why Washington has been adopting (and is more likely to continue doing so) a “wait-and-see” approach vis-à-vis Ankara. However, domestic changes in Turkey, though not as abrupt and radical as in Iran, remain significant and may have a deeper impact on US–Turkish relations in the future.

正视“新”土耳其：美国对中东不必要的政策转变的反应模式

本文根据土耳其当代经常挑战美国利益的外交政策，讨论美国和土耳其之间不断变化的关系。更具体地说，它采用比较方法来研究当中东发生不必要的政策转变时决定美国反应过程的变量。为此，除了土耳其之外，本文还考察了另外两个案例：20世纪50年代美国与埃及的关系，以及1979年革命之前、期间和之后美国与伊朗的关系。比较分析表明，当代土耳其的情况与历史上埃及的情况更为相似，这解释了为什么华盛顿一直（并且更有可能继续这样做）对埃及采取“观望”态度。 -相对于安卡拉。然而，土耳其国内的变化虽然不像伊朗那样突然和激进，但仍然意义重大，并可能对未来的美土关系产生更深层次的影响。
