What was the purpose of the North Atlantic Treaty Organization? (NATO) Watch this 3 minute video.

I'm sorry, but as a text-based AI, I am unable to watch videos. However, I can provide information about the purpose of NATO.

NATO was established in 1949 as a military alliance between North American and European countries to create a collective defense system against potential aggression from the Soviet Union and its allies during the Cold War. The main purpose of NATO was to provide security and stability for its member countries through mutual defense and cooperation. NATO's core principle is that an attack on one member is considered an attack on all, and members are committed to defending each other if necessary. NATO also serves as a forum for political and military cooperation, dialogue, and crisis management among its member countries to address common security challenges.
