Unipolarity
Unipolarity is a geopolitical structure in which one nation (hegemon) possesses overwhelming military and economic power, allowing it to shape international rules, institutions, and decisions with minimal constraint from other powers.
Real World
Between 1991 and 2003, the US acted as the world's sole superpower, demonstrated by its ability to assemble a 35-nation coalition for the Iraq War without UN Security Council approval, reflecting a level of unilateral authority no single state has held since.
Exam Focus
For 'to what extent' questions on unipolarity, always reference its decline post-2008 financial crisis and China's rise as counterevidence against US dominance.
