NATO (North Atlantic Treaty Organisation)

What is the North Atlantic Treaty Organization (NATO)?

The North Atlantic Treaty Organization, or NATO, is also known as the North Atlantic Alliance. The North Atlantic Treaty Organization (NATO) is an international military alliance founded in 1949. In response to an attack by a non-member external party, the organization establishes a system of collective defense in which its member nations agree to mutual defense.


Why was NATO formed?

The organization was founded to protect Western Europe’s common security.

Even though World War II had ended, the United States and the Soviet Union’s deteriorating relations would eventually lead to the Cold War.

The Soviet Union intended to expand its influence in Europe by spreading communism, but the United States considered the Soviet Union’s ideology a threat to its way of life. As a result, it saw the need to establish NATO.

Objectives of NATO

  • NATO’s primary and long-term goal is to protect all of its members’ freedom and security through political and military methods.
  • NATO’s political goals are to promote democratic values and enable members to consult and collaborate on defense and security issues to solve problems, establish trust, and, in the long run, avoid conflict.
  • NATO’s military objectives include the peaceful resolution of disputes. If diplomatic efforts fail, the military can execute crisis management operations.
  • These are carried out, either alone or in concert with other countries and international organizations, under the collective defense provision of NATO’s founding treaty, Article 5 of the Washington Treaty, or under a United Nations mandate.
  • NATO has only used Article 5 once, on September 12, 2001, in response to the terrorist attacks on the World Trade Center in New York.
