The modern power of the USA is based on traditional sources: the size of the territory and demographics, economy, army and soft power factors (culture, foreign policy, values, public diplomacy). The United States creates a power that has sustainable resources backed by an efficient mechanism of action and the will of the public to implement these plans. Currently, the US has enough resources, and most importantly, in the current international environment, it is able to use them to maintain an advantage over its competitors. The article presents the elements of US power that determine its advantage over other countries and the weaknesses that may limit its influence. This largely determines the research methods used (statistical and comparative). The latter method allows to determine the scale of US hegemony and what are the chances of its maintenance in the 21st century.
