From 1932 until his death in 1990, Hal Draper was a prolific Marxist writer and socialist organizer who successfully combined rigorous research and passionate outrage to assess his political era. In this still-indispensable collection of essays written in the 1950s and 60s, Draper grapples with the role of the United States in the world, situating post-war American imperialism in a global picture of capitalist competition and expansion. The essays in this volume include Draper's discussions of the United States' involvement in Guatemala, Guam, Samoa, Cuba, Vietnam, and elsewhere, as well as his, more general, socialist guide to national liberation movements.
