About 23. The USA Since 1945

After 1945, the United States emerged as the world’s dominant economic and military power, shaping the Cold War order through containment, alliances like NATO, and promotion of liberal capitalism abroad. Domestically, it experienced postwar prosperity, civil rights advances, and cultural transformations alongside persistent issues of inequality, political polarization, and debates over America’s global role.

The post-Cold War era brought unipolar dominance but also new challenges from globalization, terrorism, and rising powers like China. Recent decades have seen declining trust in institutions, partisan gridlock, and questions about sustainability of American leadership, reflecting both enduring strengths and deepening internal contradictions.
