What is the international system dominated by a sole superpower called?
Answer & explanation
Correct answer: option 4
The collapse of the Soviet Union left the world with only a single power, the United States of America. Sometimes, the international system dominated by a sole superpower, or hyper-power, is called a ‘unipolar’ system. This appears to be a misapplication of the idea of the ‘pole’ derived from physics. It may be more appropriate to describe an international system with only one centre of power by the term ‘hegemony’.
