自“阿拉伯之春”爆发后中东陷入大动荡以来，中东地缘政治发生剧烈变化，其中美国领导作用的缺失成为最突出的特点，这也意味着中东进入后美国时代。美国领导作用的缺失带来了巨大的权力真空，一时间群雄纷起逐鹿中东，中东多极化发展加速。西方在不断退缩；俄罗斯、印度、日本正积极“南下”“西进”；区域内大国土耳其、伊朗和沙特各显神通，竞争激烈。
There have been drastic changes of the geopolitics in Middle East since the outbreak of “Arab Spring” which swept through the region with unset and upheaval. The lack of United States’ leadership has become the most prominent feature in the mess，which means that the Middle East has entered the “post-American era”. The absence of the US brings out a huge power vacuum for a time in which great powers increase influence and rival in the Middle East，accelerating its pace of multi-polarization. Russia，India，Japan are actively carving out their niche “southward” or “westward”. Meanwhile，Regional powers like Turkey，Iran and Saudi Arabia are playing their edge in the fierce competition.
