who was the president that authored the idea of containment
Containment The basis of the doctrine was articulated in a 1946 cable by U.S. diplomat George F. Kennan during the post-World War II administration of U.S. President Harry S. Truman. As a description of U.S. foreign policy, the word originated in a report Kennan submitted to U.S. Defense Secretary James Forrestal in 1947, which was later used in a magazine article. It is a translation of the French term cordon sanitaire, which was used to describe Western policy toward the Soviet Union in the 1920s.
Foreign policy of the United States After the war, the U.S. rose to become the dominant non-colonial economic power with broad influence in much of the world, with the key policies of the Marshall Plan and the Truman Doctrine. Almost immediately, however, the world witnessed division into broad two camps during the Cold War; one side was led by the U.S. and the other by the Soviet Union, but this situation also led to the establishment of the Non-Aligned Movement. This period lasted until almost the end of the 20th century and is thought to be both an ideological and power struggle between the two superpowers. A policy of containment was adopted to limit Soviet expansion, and a series of proxy wars were fought with mixed results. In 1991, the Soviet Union dissolved into separate nations, and the Cold War formally ended as the United States gave separate diplomatic recognition to the Russian Federation and other former Soviet states.
