ABSTRACT
The paper aims to present some aspects of the debate about the end of the hegemony of the United States, in light of the theories of systemic cycles of accumulation and hegemonic stability. Among the conclusions, the paper shows that the North-American hegemony is diminishing not only because of the emergence of new powerful countries, such as China, but because the international system, composed by new powerful actors such as multinational corporations, global cities, religious organizations and transnational terrorist groups, is diminishing the means by which the US has exercised its global power since the mid twentieth century.
KEY-WORDS: United States; Marxism; Hegemonic Stability Theory; Systemic Cycles of Accumulation
