The Marshall Plan, also known as the European Recovery Program, was a U.S. program providing aid to Western Europe following the devastation of World War II. It was enacted in 1948 and provided more than $15 billion to help finance rebuilding efforts on the continent.
Explanation: From Google, "On December 19, 1947, President Harry Truman sent Congress a message that followed Marshall's ideas to provide economic aid to Europe. Congress overwhelmingly passed the Economic Cooperation Act of 1948, and on April 3, 1948, President Truman signed the act that became known as the Marshall Plan."
While initially, America thought it best to stay out of foreign affairs, in the Cold War, they changed their opinion drastically, practicing containment in an effort to stop the spread of communism.
