What was a major criticism of U.S. imperialism during this period?

The major criticism of U.S. imperialism during this period centered on the disregard for the rights of native peoples. This criticism reflects a fundamental ethical concern regarding the impact of imperialist policies on indigenous populations. As the United States expanded its influence overseas, particularly in territories like the Philippines, Puerto Rico, and Guam, there were numerous instances where the rights and autonomy of local populations were overlooked or actively suppressed.

The actions taken by the U.S. government—such as military interventions, the imposition of American governance, and the economic exploitation of resources—often led to the loss of land, culture, and political freedom for native peoples. Critics argued that imperialism violated principles of self-determination and respect for other nations, which are essential components of international justice and human rights.

This perspective was part of broader anti-imperialist sentiments that emerged in the early 20th century, advocating for the rights and autonomy of colonized nations and highlighting the moral contradictions inherent in promoting democratic ideals while simultaneously denying such freedoms to other populations.
