America After The Cold War by Patrick N. Allitt

A concise survey of how the United States navigated the three decades after the Cold War, tracing shifts in foreign policy, politics, and society as the country moved from post‑Soviet optimism through the shocks of 9/11, wars in the Middle East, and the 2008 financial crisis; it explores debates over the use of American power, the effects of globalization and technological change, and the growing partisan and cultural polarization that reshaped national identity and America's role in the world.
