The Vietnam War was an example of imperial aggression.… Imperialism ultimately enriches the home country's dominant class. The process involves "unspeakable repression and state terror," and must rely repeatedly "upon armed coercion and repression." The ultimate aim of modern U.S. imperialism is "to make the world safe" for multinational corporations.… U.S. imperial actions in Vietnam and elsewhere are often described as reflecting "national interests," "national security," or "national defense." Endless U.S. wars and regime changes, however, actually represent the class interests of the powerful who own and govern the country. Noam Chomsky argues that if one wishes to understand imperial wars, therefore, "it is a good idea to begin by investigating the domestic social structure. Who sets foreign policy? What interest do these people represent? What is the domestic source of their power?"
