This article analyzes the evolution of U.S. foreign policy in the South Caucasus through three concepts, “soft power”, “hard power” and “smart power” which have been developed under the administrations of Bill Clinton, George W. Bush and Barack Obama respectively. The authors also aim to identify how the US strategy towards this region has been perceived in Azerbaijan, which, due to its geographical position, energy resources and geopolitical environment, is one of the “geopolitical pivots of Eurasia”.
