Why did president Roosevelt believed the US should assert its military power in Latin America?

President Roosevelt believed the U.S. should assert its military power in Latin America to ensure stability and protect American interests in the region. He feared that European intervention could disrupt the growing influence of the United States and threaten its economic and strategic interests. His Roosevelt Corollary to the Monroe Doctrine emphasized the U.S. responsibility to intervene in Latin American nations to maintain order and prevent foreign exploitation. This approach aimed to establish the U.S. as a dominant power in the Western Hemisphere.
