NATO – North Atlantic Treaty Organization

NATO is an acronym that stands for the North Atlantic Treaty Organization; it is also known as the North Atlantic Alliance. NATO is an intergovernmental military association that is based on the North Atlantic Treaty that was signed on April 4th, 1949. NATO consists of some countries which have constituted a system of collective defense in order to respond to and counter an attack by a non-NATO member.

NATO is headquartered at Boulevard Leopold III in Brussels, Belgium.

North Atlantic Treaty Organization was formed to provide collective security to Western Europe. This is because relations between the United States and the USSR continuously deteriorated even after World War 2. The USSR was looking to expand itself in Europe by spreading communalism. The United States saw this move by the USSR as a threat to the defense system of their country and hence decided to form NATO.

History of NATO

Before we start to learn about the working style of NATO, let’s take a brief look at its history.

  • World War 2 happened in 1945. Soon after that, western Europe underwent a financial and military crisis.
  • In 1948, the United States granted the fund to some countries in Europe on the condition that they would cooperate with each other and accelerate their mutual recovery.
  • By the end of the Second World War, the United States and the USSR had developed certain clashes that eventually led to the cold war between them. Because the USSR wanted to expand its arms in Europe by spreading communalism, whereas the United States saw this as a threat to its military.
  • In 1955, the cold war was geared up between the USSR and the United States. As a result of this, the Soviet Union signed a pact. This pact was called the Warsaw Pact, which was purely a military-political alliance. This pact was seen as a direct counterbalance to NATO.
