This chapter challenges Fukuyama’s “End of History” thesis by tracing the evolution of global power since the collapse of the Soviet Union in 1991—a watershed moment that redefined international relations. It contrasts Russia’s post-Soviet economic collapse with the explosive economic rise of China and the dramatic accumulation of wealth in the West, highlighting unprecedented global inequalities. The chapter details China’s meteoric economic and technological ascent—from eradicating extreme poverty and transforming its manufacturing sector to surpassing Western rivals in scientific output and patent production. It also explores how the dynamics of globalization have reconfigured global trade and economic power, exemplified by the dramatic shift in trade volumes between the U.S. and China. Drawing on the concept of Thucydides’ Trap and Mearsheimer’s Realist theory, the analysis underscores the inevitable tensions of a multipolar world where rising powers challenge established hegemony. Ultimately, the chapter calls for urgent, nuanced diplomatic efforts to avert conflict in an era marked by shifting power balances, deep structural inequalities, and the persistent threat of global instability.
