Answer:
The right of the United States to involve itself in Latin American affairs whenever necessary
Step-by-step explanation:
The Roosevelt Corollary (1904) was a United State policy in which the American government declared itself with the right to act as international police in the conflicts between European countries and the Western Hemisphere (Latin American countries). This meant that if a European country pressed their claims directly to the countries of the Western Hemisphere (such as large debts and civil unrest) the U.S. would intervene.
The Corollary put a limit to European abuses toward Latin America, it displayed how the United States would take a more aggressive role in the world and it established the U.S.'s right to involve itself in Latin American affairs whenever necessary.
