a. Long Cycle Theory

Explanation:

In international relations theory, the Long Cycle Theory was first presented by  George Modelski in his book Long Cycles in World Politics (1987). Modelski claims that the US replacing Britain as the leader of the International System after World War II is part of a cycle in international relations where one hegemon is gradually replaced by another over a period of roughly a century.

The transition from one hegemonic power to another leads to the new world power carrying on the costs associated with such a position. And unlike defenders of the realist school of international relations, Modelski doesn't see this cycle as produced by the anarchy of the internationals system, but rather as a natural consequence of economic and political developments, including wars. According to him, Portugal was the world hegemon in the 16th century, Netherlands in the 17th century, Britain stretched his period of international dominance over the 18th and 19th century, and since the 20th century, the United States is the world's dominant hegemon.
