Final answer:
The Roosevelt Corollary to the Monroe Doctrine allowed the United States to act as an 'international police power' in Latin America, justifying intervention to maintain regional stability and economic interests, which proved to be imperialistic from Latin America's view.
Step-by-step explanation:
The Roosevelt Corollary to the Monroe Doctrine was articulated by President Theodore Roosevelt as a significant addition to American foreign policy. In 1904, he declared that the United States had the right to intervene as an international police power in the affairs of nations throughout the Western Hemisphere, especially when their instability might invite European intervention, which the U.S. sought to prevent.
Roosevelt's justification for this policy was to maintain order and ensure that debts were repaid to European and American creditors, thereby maintaining U.S. dominance in the hemisphere and preventing potential European involvement. This interventionist policy was cloaked as an extension of the Monroe Doctrine but was seen by Latin American countries as a pretext for American imperialism. It was later replaced by the Good Neighbor Policy under Franklin Roosevelt in the 1930s.
