The North Atlantic Treaty Organization (NATO) was created by the United States after World War II. Post World War II brought on a competition between the US and Soviet Union for global influence and power. In this competition, the US wanted to stop the spread of communism (aka containment). This was a goal of the federal government because the US feared that if communism spread to one country, that it would continue to spread to neighboring countries. This is what the government called the domino effect.
To prevent this domino effect, the US created NATO as a means to organize their European allies against the spread of communism.
