Albert Beveridge's 'Defense of Imperialism' articulates the belief that Americans are divinely destined to govern and expand territories like the Philippines, Cuba, and Puerto Rico, which he argues are not ready for self-governance. He frames imperialism as a necessary endeavor for national greatness and a moral duty to uplift those deemed incapable of ruling themselves. Beveridge's justification for American expansionism encompasses both the perceived obligation to civilize and the commercial advantages it brings to the United States.
