Step-by-step explanation:
The 1904 "Roosevelt Corollary" stated that the U.S. had a right to intervene in the affairs of neighboring countries. It was an addition to the Monroe Doctrine, which was issued in 1823 and aimed to prevent European colonization in the Americas. The Roosevelt Corollary, however, extended this doctrine to justify U.S. intervention in Latin American countries to maintain stability and protect U.S. economic interests. This policy was created as a response to a military crisis in Cuba and allowed the U.S. to become a dominant power in the Western Hemisphere.
