The Evolution and Legacy of the Monroe Doctrine

TLDR The Monroe Doctrine was a unilateral statement by the United States outlining its policy for the Western Hemisphere, which initially had little enforcement power but later led to military interventions in several Latin American countries. The Doctrine evolved over time to include actions against communism and drug cartels, but by the 21st century, it was officially declared dead.
