Why did Roosevelt justify increased involvement in Latin America?

Roosevelt justified increased involvement in Latin America primarily through the Monroe Doctrine, which he reinterpreted to assert that the United States had the right to intervene in the region to maintain stability and prevent European interference. He believed that a strong U.S. presence could promote economic development and political stability, thereby safeguarding American interests. This approach was epitomized by the Roosevelt Corollary, which stated that the U.S. would act as a "policeman" in the Western Hemisphere to curb unrest and protect both itself and its neighbors.
