Monroe Doctrine

The Monroe Doctrine is a United States foreign policy position that opposes European colonialism in the Western Hemisphere, stating that any intervention in the political affairs of the Americas by foreign powers is a potentially hostile act against the US. First articulated by President James Monroe in 1823, the doctrine was central to American grand strategy in the 20th century and was successfully enforced by the US in the early 20th century. The doctrine was later reinterpreted in the early 20th century to promote multilateralism and non-intervention, and continues to be variably denounced, reinstated, or reinterpreted in the 21st century.learn more on wikipedia
