Why did the United States introduce the Marshall Plan in the post-war era? to stabilize Europe and support democratic governments
to encourage Europe to share its post-war prosperity with the United States
to help the USSR in forming a democratic government
to boost economic recovery in the United States following World War II

The objectives of the United States were to rebuild those areas destroyed by the war, eliminate barriers to trade, modernize European industry and make the continent prosperous again; all these objectives were intended to prevent the spread of communism, which had a large and growing influence in post-war Europe
