The Monroe Doctrine is the best known U.S. policy toward the Western Hemisphere. Buried in a routine annual message delivered to Congress by President James Monroe in December 1823, the doctrine warns European nations that the United States would not tolerate further colonization or puppet monarchs.
Actually, Secretary of State Adams, who had convinced Monroe to issue the Doctrine, realized the US could not enforce the provisions of the Monroe Doctrine, but Great Britain had previously proposed that the two nations issue a proclamation that the Western Hemisphere was closed to further colonization.
