Answer:
The Monroe Doctrine, in asserting unilateral U.S. protection over the entire Western Hemisphere, was a foreign policy that could not have been sustained militarily in 1823. Monroe and Adams were well aware of the need for the British fleet to deter potential aggressors in Latin America.
The Monroe Doctrine was a significant statement of American foreign policy. In President James Monroe's seventh State of the Union address, he made it clear that America would not allow European colonies to further colonize in the Americas or interfere with independent states.
The main purpose of the Monroe Doctrine was to remove all ties from England and Britain to the U.S land.
The doctrine was an outgrowth of concern in both Britain and the United States that the continental powers would attempt to restore Spain 's former colonies, in Latin America, many of which had become newly independent nations. The United States was also concerned about Russia 's territorial ambitions in the northwest coast of North America.
The motivation was to "prevent further European colonization in the Caribbean region". The Monroe Doctrine was created in light of the fact that the US and England were worried over the possibilities of European colonial extension in the Americas
