The United States would act to prevent Latin American countries from interfering in Europe

One of the main characteristics of the Roosevelt Corollary was that the United States would act as a police officer in the Western Hemisphere.

Explanation:

The Roosevelt Corollary was announced on December 6, 1904 by President Theodore Roosevelt in his annual message to the Congress as a supplement to the Monroe Doctrine.

With the Corollary, Roosevelt decisively changed the previous interpretation of the Monroe Doctrine. If the latter had only rejected the European powers' right to intervene on the American continent, Roosevelt additionally postulated an explicit arbitration function by the United States, combined with an intervention right in the case of intra-American conflicts. Even if the United States had intervened repeatedly in conflicts in other American states before 1904, this was not clearly compatible with the original content of the Monroe Doctrine, according to which the American states were supposed to clarify their affairs on their own. Earlier interventions by the United States had therefore always met with vehement resistance in their own country. President Roosevelt broke with a long tradition of isolationism in American foreign policy, and was accused of acting against the requirements of the Constitution, breaking international law and pursuing a militaristic and imperialist foreign policy.

The correct answer is that The United States would intervene in Latin American affairs in order to keep European countries out.

This was directed primarily at Spain.
