We examine the United States after the collapse of the Soviet Union, when the nation emerged as the world's lone superpower facing new opportunities and new challenges. This episode explores shifts in foreign policy, economic globalization, technological change, and cultural debates in the late twentieth and early twenty-first centuries. We'll look at how issues like terrorism, trade, immigration, and political polarization reshaped American life in the absence of a single defining global rival. As the course nears its end, this lesson highlights how Americans navigated uncertainty in a post–Cold War world while redefining national priorities at home and abroad.
