The Role of the NATO in Collective Security and how it has transformed and evolved over the years

This paper is about how and for what purpose NATO as an organization for collective security was established. To begin with, this paper says that NATO was established to counter and contain the communist threat in the shape of Russia. This was an era of the cold war. However, once the cold war was over and Russian disintegration happened in 1989, NATO didn't disappear but defined for itself a changing role in the changing world. It was because of this newly defined role that NATO survived and outlived its primary purpose. However,since the terrorists' attack on the twin towers on 9/11, NATO has further transformed to undertake military operations in areas that fall beyond its scope of operations. It has been seen as involved not only in military operations but also in humanitarian assistance in countries hit by natural calamities. Data for the paper was collected through secondary sources, including research papers and other collectable materials.
