Containment

Containment

Containment was the U.S. strategy and policy of stopping the spread of communism beyond the regions where it already existed.

It was strongly associated with George Kennan, who argued that the Soviet Union would keep expanding if it was not checked.

Main Idea

• do not let communism spread farther

• resist Soviet influence abroad

• limit communist expansion rather than directly destroy it everywhere

Methods

Containment used:

• military pressure

• political alliances

• economic support

• diplomatic intervention

It became a guiding principle of U.S. foreign policy throughout the Cold War.

Historical Impact

Containment shaped later U.S. actions, including:

• the Truman Doctrine

• support for the Marshall Plan

• the Korean War

• the Vietnam War

• many other conflicts across Asia, Africa, and Latin America
