The contents of the Truman Doctrine
He committed to giving military, political and financial aid to countries to stop the spread of communism.
The Marshall Plan (or Marshall Aid) formalised the economic assistance that Truman described in the Truman Doctrine of 1947.
Politicians argued that the Soviets were trying to isolate Eastern Europe from the West by installing communist governments and banning them from accepting aid.
The USA thought that giving rebuilding, poor nations money would stop people from supporting communism. Demanding equality and redistribution of all wealth was likely to be more attractive to starving & unemployed people than employed and wealthy individuals in a prosperous nation.
US perspective on the Marshall Plan
The Soviet Union saw both the 1947 Truman Doctrine and the 1947 Marshall Plan as a threat to Eastern Europe.
--> The Soviet Politburo viewed the Marshall Plan as an example of America's "economic imperialism"
