Changes in the World Power: The United States within the New Balance of Power
This article aims to analyse the behaviour of the United States as a world power. The working hypothesis is that the only superpower has become, nowadays, impotent, affected by a relative decline. However, this should be understood as something natural, since it has never happened that any society would permanently remain ahead of the others. We assume here that the use of the qualitative method, through the hermeneutic analysis is, certainly, the basic methodology used for this investigation. We will try to conclude that notwithstanding their relative decline, the USA will tend to remain, in the short and medium term, the only world superpower. It is recommended that further investigation must assign a special attention to China’s emergence and its consequences on the balance of world power, in particular with regard to the durability of American hegemony.
