Donald Trump’s election to the U.S. presidency in 2016, which placed control of the government in the hands of the most racially homogenous, far-right political party in the Western world, produced shock and disbelief for liberals, progressives, and leftists around the world. Yet most of the immediate analysis neglects longer term accounting of how the United States arrived here. Race and America’s Long War examines the relationship between war, politics, police power, and the changing contours of race and racism in the contemporary United States. Spanning the course of U.S. history, these essays show how the return of racism and war as seemingly permanent features of American public and political life is at the heart of the present crisis and collective disorientation. Nikhil Pal Singh argues that the U.S. pursuit of endless war since the September 11 terrorist attacks has reanimated a longer history of imperial-statecraft that segregated and eliminated enemies both within and overseas, frequently blurring the boundaries between the two. America’s territorial expansion and Indian removals, settler in-migration and nativist restriction, African slavery and its afterlives were formative social and political processes that drove the rise of the United States as a capitalist world power long before the onset of globalization. At a time when American commitments to globalism appear to have entered a terminal crisis, Race and America’s Long War shows how these interconnected histories of racial division and war-making again occupy the nexus of public concern and governmental power.
