Supporters of U.S. expansion during the period of American imperialism held several key beliefs that justified their stance:
-
Economic Interests: Advocates argued that expansion would enhance American economic power by providing access to new markets and resources. This included the potential for increased trade and the exploitation of valuable resources from newly acquired territories.
-
Spreading Civilization: Proponents like Senator Albert Beveridge believed in a mission to spread American values, government policies, and culture. They viewed U.S. expansion as a way to bring "civilization" and "order" to regions they perceived as lacking effective governance.
-
Military Protection: Supporters contended that American presence would offer military protection to these territories. They believed that U.S. governance would ensure stability and prevent anarchy or tyranny, thereby creating a safer environment for both American settlers and local populations.
-
Manifest Destiny: The belief in Manifest Destiny—the idea that the United States was destined to expand across the continent and beyond—also fueled imperialist sentiments. Many saw the expansion as a natural extension of American progress and a fulfillment of their national destiny.
-
National Prestige: Expansion was often viewed as a way to enhance the United States’ standing on the global stage. By acquiring new territories, supporters believed the U.S. could assert itself as a powerful and influential nation among world powers.
-
Cultural Superiority: Many supporters held ethnocentric views, believing that American culture and democracy were superior and should be spread to other parts of the world. They often framed imperialism as a benevolent effort to uplift and modernize other societies.
Overall, those in favor of U.S. expansion framed it within contexts of opportunity, duty, and national pride, viewing it as beneficial not only for the United States but also for the territories involved.
