This material seems to be the "European economic recovery plan" implemented by the United States to western European countries after World War II 1946, which is also commonly known as the "Marshall Plan". Specifically, the United States contributed1200 million dollars to provide funds, technology and raw materials for European economic recovery, stabilize the economies of western European countries, and help countries carry out post-war reconstruction and recovery. Its purpose is: 1, to curb the spread of socialist thoughts in western European countries; 2. Strengthen American economic and political control over western European countries; 3. Prevent the political infiltration of socialist countries in Eastern Europe headed by the Soviet Union into western European countries.

This principle of the United States is the concrete embodiment of the "cold war mentality". Since then, the world has been divided into two camps, the East and the West, led by the United States and the Soviet Union, and a worldwide "cold war" has begun.
