To commit the United States to involvement in European affairs.
The United States, along with Canada, joined with ten European countries in signing the North Atlantic Treaty in 1949. This created the North Atlantic Treaty Organization (NATO), which was a defensive military alliance of democratic states over against the threat of communism felt in the Cold War environment.
Foreign policy positions of American administrations, such as the Truman Doctrine and the Eisenhower Doctrine, also aimed in the direction of commitment to involvement in European affairs.
