Containment was a foreign policy strategy followed by the United States during the Cold War. First laid out by George F. Kennan in 1947, the policy stated that communism needed to be contained and isolated, or else it would spread to neighboring countries. American foreign policy advisors believed that once one country fell to communism, each surrounding country would fall as well, like a row of dominoes. This view was known as the domino theory. Adherence to the policy of containment and domino theory ultimately led to U.S. intervention in Vietnam as well as in Central America and Grenada.

Containment Definition

Containment was a foreign policy of the United States of America, introduced at the start of the Cold War, aimed at stopping the spread of communism and keeping it "contained" and isolated within its current borders of the Union of Soviet Socialist Republics (U.S.S.R. or the Soviet Union). The U.S. feared a domino effect would cause communism to spread from one country to the next, allowing communist regimes to dominate the region. The solution: cutting communist influence off at its source by enticing struggling nations with more funding than communist countries could provide.

Although containment may have specifically been meant as a term to describe the U.S. strategy for the curtailment of communism from spreading outward from the Soviet Union, the idea of containment as a strategy for cutting off nations such as China and North Korea still persists to this day.

Containment Policy

The Cold War began after World War Two when nations formerly under Nazi rule ended up split between the conquests of the U.S.S.R. and the newly freed states of France, Poland, and the rest of Nazi-occupied Europe. Since the United States had been a key ally in liberating western Europe, it found itself deeply involved in this newly divided continent: Eastern Europe wasn't being turned back into free states, but rather being placed under the military and political control of the Soviet Union.

Further, western European countries appeared to be wobbling in their democracies because of socialist agitation and collapsing economies, and the United States began to suspect that the Soviet Union was deliberately destabilizing these countries in an effort to bring them into the folds of communism. Even countries themselves were dividing in half over the ideas of how to move forward and recover from the last world war. This resulted in a lot of political and indeed military turmoil for the years to come, with such extremes as the Berlin Wall being established to separate East and West Germany due to the opposition to communism.

The United States developed its policy of containment to prevent communism from spreading further into Europe and the rest of the world. The concept was first outlined in George Kennan's "Long Telegram," which he sent from the U.S. Embassy in Moscow. The message arrived in Washington, D.C., on February 22, 1946, and was circulated widely around the White House. Later, Kennan published the document as an article titled "The Sources of Soviet Conduct"—which became known as X Article because Kennan used the pseudonym "Mr. X."

The policy of containment was adopted by President Harry Truman as part of his Truman Doctrine in 1947, which redefined America's foreign policy as one that supports the "free people who are resisting attempted subjugation by armed minorities or outside pressures." This came at the height of the Greek Civil War of 1946-1949 when much of the world was waiting to see which direction Greece and Turkey would go, and the United States agreed to help both countries to avoid the possibility that the Soviet Union would lead them to communism.

The Creation of NATO

Acting deliberately, at times aggressively, to involve itself in the border states of the world and prevent them from turning communist, the United States spearheaded a movement that would eventually lead to the creation of the North Atlantic Treaty Organization (NATO). The group alliance represented a multi-national commitment to halting the spread of communism. In response, the Soviet Union signed an agreement called the Warsaw Pact with Poland, Hungary, Romania, East Germany, and several other nations.

Containment in the Cold War: Vietnam and Korea

Containment remained central to American foreign policy throughout the Cold War, which saw rising tensions between the United States and the Soviet Union. In 1955, the United States entered what some historians consider a proxy war with the Soviet Union, by sending troops into Vietnam to support the South Vietnamese in their battle against the communist North Vietnamese. The United States' involvement in the war lasted until 1975, the year the North Vietnamese captured the city of Saigon.

A similar conflict took place during the early 1950s in Korea, which was likewise divided into two states. In the fight between North Korea and South Korea, the United States backed the South, while the Soviet Union backed the North. The war ended with an armistice in 1953 and the establishment of the Korean Demilitarized Zone, a 160-mile barrier between the two states.
