This advice to President Harry Truman helped influence Truman's decision to develop the Marshall Plan.

Explanation:

On April 3th, 1948, Truman signed the Cooperation Act which was based on George C. Marshall's ideas: If America wanted to set a world order in which democracy and market economy were not threatened, it was necessary to help European Nations which were still free from Soviet influence to recover from the disaster caused by WWII.

European nations enthusiastically attached to the plan and collaborated from the start. This act gave origin to the European Recovery Program, also known as the Marshall Plan.
