61. What is the Monroe doctrine?

The Monroe Doctrine is a policy of the United States introduced on December 2, 1823. It stated that further efforts by European nations to colonize land or interfere with states in North or South America would be viewed as acts of aggression requiring U.S. intervention.^[1] The Doctrine noted that the United States would neither interfere with existing European colonies nor meddle in the internal concerns of European countries.

The intent and impact of the Monroe Doctrine persisted with only minor variations for almost two centuries. Its primary objective was to free the newly independent colonies of Latin America from European intervention and control that would make the New World a battleground for the Old. The doctrine put forward that the New World and the Old World were to remain distinctly separate spheres of influence, for they were composed of entirely separate and independent nations.

62. What is the Marshall plan?

The Marshall Plan (officially the European Recovery Program, ERP) was the large-scale American program to aid Europe where theUnited States gave monetary support to help rebuild European economies after the end of World War II in order to prevent the spread of Soviet communism.^[1] The plan was in operation for four years beginning in April 1948. The goals of the United States were to rebuild a war-devastated region, remove trade barriers, modernize industry, and make Europe prosperous again. The initiative was named after Secretary of State George Marshall

The reconstruction plan, developed at a meeting of the participating European states, was established on June 5, 1947. It offered the same aid to the Soviet Union and its allies but they did not accept it^[3][4], as to do so would be to allow a degree of US control over the Communist economies ^[5]. During the four years that the plan was operational, US $13 billion in economic and technical assistance was given to help the recovery of the European countries that had joined in the Organization for European Economic Co-operation. This $13 billion was in the context of a U.S. GDP of $258 billion in 1948, and was on top of $13 billion in American aid to Europe between the end of the war and the start of the Plan that is counted separately from the Marshall Plan.^[6] The Marshall Plan was replaced by the Mutual Security Plan at the end of 1951.
