美国在中亚地区的外交政策始终围绕安全利益、政治利益和能源利益三个目标而展开，不同时期、不同的地区安全环境、不同的战略考量，使得这三个目标的排序不同。在2014年底前从阿富汗撤出美军战斗部队，是奥巴马上台后美国政府对10年反恐战争进行战略纠错，进而完成战略重心向亚太地区转移的关键环节。
Three major objectives, i.e., security, political interest and energy, have been serving the US policy towards Central Asia with the corresponding activities in this region. The order of priority of the three objectives is determined by different regional security environment and different strategic consideration in different time. The withdrawal of the US troops from Afghanistan by the end of 2014 serves a strategic correction of the 10-year anti-terrorist war since the inauguration of Obama administration. As prearrangement, the US withdrawal is the key step for US strategy focus to transfer to the Asia-Pacific region.
